Consider the following mutual authentication protocol using Symmetric Key Crypto. The symmetric key K is only known to Alice and Bob. Messages exchanged over the network can be observed. E is a symmetric encryption algorithm. Rais a nonce. Alice -> Bob: "I'm Alice", RA Bob -> Alice: E(RAK) Alice -> Bob: E(RA+1, K) Which of the following descriptions is correct about this protocol? This protocol is subject to reflection attacks. This protocol is secure. This protocol is subject to replay attacks. This protocol is subject to both reflection attacks and replay attacks.

Answers

In the protocol, the messages exchanged are as follows: Alice -> Bob: "I'm Alice", RA Bob -> Alice: E(RAK) Alice -> Bob: E(RA+1, K)

Here, Alice uses her secret key K to encrypt a nonce RA and sends it to Bob. Bob sends Alice a message encrypted with Alice’s public key, which Alice then decrypts with her private key. Bob sends a message back to Alice encrypted with the symmetric key, which Alice can decrypt using her secret key. This protocol is secure.

This protocol is secure because it uses symmetric key cryptography, which provides strong encryption and decryption capabilities. Symmetric encryption is one of the most basic encryption techniques, in which the same key is used for encryption and decryption. Since the symmetric key K is only known to Alice and Bob, the messages exchanged over the network can be observed, but the contents of the messages cannot be read without the key. Therefore, this protocol is secure.

Define interleaving interleaving. [2]
List and define the two storage media groups [4]

Answers

Interleaving is a computer memory technique in which data is stored in a non-contiguous manner, which means that it is scattered across various locations in memory rather than being kept together.

Interleaving is commonly used in memory management to minimize the effect of memory access latency, which is the time it takes to read or write data to or from memory.
In addition, interleaving helps to increase memory throughput and reduce the likelihood of cache misses, which are events in which the CPU requests data that isn't stored in cache memory, resulting in longer access times. Interleaving improves memory performance by allowing data to be accessed from memory in a more efficient manner.

There are two main storage media groups, which are as follows:
1. Primary Storage: Primary storage refers to a computer's main memory, which is used to store data and instructions that are actively being processed by the CPU. Primary storage is divided into two categories: Random Access Memory (RAM) and Read-Only Memory (ROM).

RAM is volatile memory, which means that its contents are lost when the computer is turned off or restarted. ROM, on the other hand, is non-volatile memory, which means that its contents are retained even when the computer is turned off or restarted.
2. Secondary Storage: Secondary storage refers to external devices that are used to store data and programs that are not currently being used by the computer. Secondary storage is divided into two categories: Magnetic Storage and Solid State Storage.

Magnetic storage uses magnetic disks or tapes to store data, while solid-state storage uses flash memory to store data. Solid-state storage is faster and more reliable than magnetic storage, but it is also more expensive.

What will be the pressure head of a point in mm of Hg if pressure head of that point is equal to 61 cm of water? Assume specific gravity of Hg is equal to 13 6 and specific weight of water is 9500 Nim (Marks 3)

Answers

The pressure head of the point in mm of Hg is 819.9 mm of Hg.

Pressure head of a point = 61 cm of water Specific gravity of Hg = 13.6 Specific weight of water = 9500 N/m³To find: The pressure head of a point in mm of Hg. We know that: Total pressure head = pressure head due to water + pressure head due to mercury We know that the pressure head due to water is given by: H = ρghWhere,ρ = Specific weight of water g = Acceleration due to gravity h = Height of water column H = (9500 x 9.81 x 61) / 100 cm H = 5736.15 / 100 cm H = 57.3615 m Hence, the pressure head due to water is 57.3615 m. We know that the pressure head due to mercury is given by: Hg = ρghWhere,ρ = Specific gravity of Hg g = Acceleration due to gravity h = Height of mercury column Let's calculate the height of mercury column: Hg = (13.6 x 9.81 x h) / 100 cm61 cm of water is equal to 57.3615 m of water. Hence, height of mercury column = (57.3615 x 100) / (13.6 x 9.81) cm Height of mercury column = 432.5 cm = 4.325 m Now, we can calculate the pressure head of the point as follows: Total pressure head = pressure head due to water + pressure head due to mercury Total pressure head = 57.3615 + 4.325Total pressure head = 61.6865 m Now, we have to convert this into mm of Hg. We know that:1 m of Hg = 1000 mm of Hg1 m of water = 1000 mm of water We can use the following formula for the conversion of pressure head from meters to millimeters: Hg = (ρHg / ρw) x H w x 1000Where,ρHg = Density of mercury ρw = Density of water H w = Pressure head due to water Hg = (13600 / 1000) x 61.6865 x 1000 / 9500Hg = 819.9 mm of Hg Hence, the pressure head of the point in mm of Hg is 819.9 mm of Hg. Total pressure head = 61.6865 m Hence, the pressure head of the point in mm of Hg is 819.9 mm of Hg.                                                In this question, we have been given the pressure head of a point in cm of water and we are supposed to find the pressure head of the point in mm of Hg. We know that the total pressure head is the sum of the pressure head due to water and the pressure head due to mercury. We have used the formula for pressure head due to water which is H = ρgh. By substituting the given values, we got the pressure head due to water. Then we used the formula for pressure head due to mercury which is Hg = ρgh. We found the height of mercury column from the given specific gravity of Hg and the pressure head of water. Then we found the total pressure head by adding the pressure head due to water and the pressure head due to mercury. Finally, we converted the total pressure head into mm of Hg using the formula for the conversion of pressure head from meters to millimeters. Hence, the pressure head of the point in mm of Hg is 819.9 mm of Hg.

Design an active HPF with gain of 5 and a corner frequency of 200 Hz. (Use input resistance of 20 kohm) • Find Transfer Function for the circuit, H(w) = G(w) Vo(w)/Vi(w). [Q2] Find poles and zeros for the circuit. . [Q3] Draw network analyzer trace (2-D graphs) for ( |H (W) 4B VS W). . [Q4] Explain filter characteristics in your own words

Answers

An active high-pass filter (HPF) with a gain of 5 and a corner frequency of 200 Hz can be created utilizing a circuit consisting of a resistor, a capacitor, and an operational amplifier.

This can be accomplished by combining a standard inverting amplifier with a capacitive circuit. To find the transfer function for the circuit, the next step is to utilize the formula for an inverting amplifier's gain. It is given as follows: Gain = -Rf / Rin, where Rf is the feedback resistance and Rin is the input resistance of the amplifier. As a result, the gain equation for the circuit in this example can be written as follows:

Gain = -Rf / Rin = -5Rin / Rin = -5For the circuit, the transfer function can be expressed as H(w) = G(w) Vo(w)/Vi(w) = -5 / (1 + jw/200)The circuit's poles and zeros can also be calculated using this equation. Because it is a high-pass filter, the transfer function will have one zero and one pole. The pole's frequency will be the corner frequency (200 Hz), and the zero's frequency will be much higher than the pole's frequency. As a result, the zero can be ignored, and only the pole is important. The circuit's network analyzer trace can also be drawn, which is a two-dimensional graph of |H(w) 4B vs. w. This graph can help to comprehend the circuit's frequency response. The magnitude response of the circuit can be observed, which is the absolute value of H(w).

Finally, the filter's characteristics can be explained. In essence, the filter works by blocking low-frequency signals and passing high-frequency signals. When a signal is applied to the input of the circuit, the capacitor resists the signal at low frequencies but allows the signal to pass at high frequencies. As a result, the output of the circuit is a high-pass filtered signal. The gain of the filter is determined by the resistors used in the circuit, and the corner frequency is determined by the capacitor's value and the input resistance of the amplifier. When designing filters, it is critical to choose component values that are appropriate for the application's frequency range and gain requirements.

Therefore, the circuit can be created utilizing a resistor, a capacitor, and an operational amplifier. The transfer function for the circuit is H(w) = G(w) Vo(w)/Vi(w) = -5 / (1 + jw/200), and the circuit has one pole and one zero. The network analyzer trace of the circuit can also be drawn, which is a two-dimensional graph of |H(w) 4B vs. w. Finally, the circuit works by blocking low-frequency signals and passing high-frequency signals, and its gain and corner frequency are determined by the resistors and capacitors utilized in the circuit.

A pipe is carrying water under steady flow condition. At end point 1, the pipe diameter is 1.2 m and velocity is (x+ 30) mm/h, where x is the last two digites of your student ID. At other end called point 2, the pipe diameter is 1.1 m, calculate velocity in m/s at this end.

Answers

The question is asking about the velocity of water in a pipe with diameter 1.1 m at point 2. Given that the pipe is carrying water under steady flow condition, which means that the water is not accelerating or decelerating, the continuity equation applies.

The continuity equation states that the mass flow rate of a fluid is constant, and it is expressed as:mass flow rate = ρ * A * vwhere ρ is the density of the fluid, A is the cross-sectional area of the pipe, and v is the velocity of the fluid.Since the pipe is under steady flow condition, the mass flow rate at point 1 is equal to the mass flow rate at point 2. Therefore, we can write:ρ1 * A1 * v1 = ρ2 * A2 * v2where the subscript 1 denotes conditions at point 1 and the subscript 2 denotes conditions at point 2.Since we want to find v2, we can rearrange the equation as:v2 = (ρ1 * A1 * v1) / (ρ2 * A2)We are not given the density of water, but we can assume it to be 1000 kg/m³ at room temperature and standard atmospheric pressure. Therefore,ρ1 = ρ2 = 1000 kg/m³We are also given that the diameter of the pipe at point 1 is 1.2 m, which means that the radius is 0.6 m, and the area is: A1 = π * (0.6 m)² = 1.13 m²We are given the velocity at point 1 as (x + 30) mm/h. Since we want the velocity in m/s, we need to convert it as follows:(x + 30) mm/h = ((x + 30) / 1000) m/sAt point 2, the diameter of the pipe is 1.1 m, which means that the radius is 0.55 m, and the area is: A2 = π * (0.55 m)² = 0.95 m²Now we can substitute the values into the equation for v2:v2 = (ρ1 * A1 * v1) / (ρ2 * A2)= (1000 kg/m³) * (1.13 m²) * ((x + 30) / 1000) m/s / (1000 kg/m³) * (0.95 m²)= (1.13 / 0.95) * (x + 30) m/s≈ (1.19) * (x + 30) m/sTherefore, the velocity of water at point 2 is approximately 1.19 times (x + 30) m/s.

Answers

One of the factors of computer failures was the reuse of software from another system.

This is because when software is transferred from one system to another, there may be compatibility issues that may not be visible in the first place. Also, the software may not work properly in the new system due to the differences in the environments. Thus, the reuse of software components may lead to computer failures.

Among the given options, the use of standard software components and artificial intelligence systems were not factors of computer failures. On the other hand, contracting out programming to overseas firms was a factor of computer failures as it may lead to communication and quality issues due to the differences in language, culture, and time zones.

In the brainstorming phase of analyzing ethical cases, listing professional code sections that apply is not a part of it.

The brainstorming phase of analyzing ethical cases includes listing risks, issues, problems, consequences, listing all people and organizations affected (stakeholders), and listing possible actions. The professional code sections that apply will come later when analyzing the ethical case and determining what actions should be taken.

Design of Fiber System:In the design of the fiber system, the first step is to calculate the power and bandwidth budget calculations that include the source, fiber, and detector of your choice. It is important to choose any component that you like, but the parameter values for those components should be actual values sourced from any textbook or online data sheet that you find. You must include these as references in your report.The next step is to choose a QAM order of 4 and a filter length of 100. A roll-off factor of 0.1 is used for the pulse shaping filter. The pulse shaping filter is designed using a square-root raised cosine filter. The noise variance for an SNR of -20 dB is calculated. The source symbol generation is done by generating a random sequence of bits. A QAM mapping is then used for the phase shift of QAM mapping. The QAM signal modulation is performed by taking the square root of 2 and then adding a phase shift of pi/4 times 1+2 times the sequence of bits. A preallocated memory is then used for the upsampled QAM signal pulse shape.The signal is then passed through a matched filter for RZ modulation. The signal is then passed through an AWGN channel and the output is downsampled. The next step is to detect the signal using a RZ detection window. A simulated BER estimation is then done. The result shows that the error rate is less than 10^-9.The system is designed in such a way that it provides some reasonable bandwidth and power budget margin but does not overdesign the system. This is important to please the boss as an overdesigned system would be too expensive. Therefore, the system is designed to meet the required error rate of 10^-9 but not overdesigned.

Thus, it can be concluded that the Matlab code to design a fiber system to transmit 2 Gbits/sec (RZ) over a 5000-km path is successfully written. A reasonable bandwidth and power budget margin is provided without overdesigning the system. A simulated BER estimation is done and the result shows that the error rate is less than 10^-9. Thus, the designed system is able to meet the required error rate of 10^-9 without being too expensive.

A rock mass has the following characteristics: the compressive strength of the intact rock is 80 MPa, the RMR (Rock Mass Rating) is 62%, and the GSI (Geological Strength Index) is 50. Estimate the in-situ deformation modulus, Em.

Answers

The in-situ deformation modulus, Em is the ratio of applied stress (p) to the corresponding strain (e). Em = σ/e. The deformation modulus of rocks is the value of stress required to generate a certain strain, which describes the rock’s elastic deformation behavior. The Geological Strength Index (GSI) and the Rock Mass Rating (RMR) are used to determine the deformation modulus. The GSI and RMR are used to determine the deformation modulus. Em can be estimated using GSI, RMR, and the intact rock strength as follows:

Main answer:

Em = α (RMR + 100) mi / SRF × σci / e50, where mi = 50 + 15 log10σci.α = constant of proportionality, which varies between rock types.SRF = Spacing of rock fracturesσci = Intact rock strength

Here, Em can be calculated as follows:

Em = α (RMR + 100) mi / SRF × σci / e50First, we calculate the mi using the following formula:

mi = 50 + 15 log10σci= 50 + 15 log1080= 50 + 15 × 1.9085= 78.6325

Now we calculate α by using the following relation:

α = 0.012 for a compressive strength of 80 MPa

Therefore,α = 0.012Em = α (RMR + 100) mi / SRF × σci / e50= 0.012 × (62 + 100) × 78.6325 / 1 × 80 / e50= 0.012 × 162 × 78.6325 / e50= 155.5209 / e50

To calculate e50, we can use the following relation:

e50 = 0.5 (0.73σci / Em)^(2/3)

Now, substitute the values of σci and Em:

e50 = 0.5 (0.73 × 80 / 155.5209)^(2/3)= 0.0116

From the above calculations, we have,

Em = 155.5209 / e50= 155.5209 / 0.0116= 13402.6724 MPa

Therefore, the estimated in-situ deformation modulus, Em is 13402.6724 MPa.

Answers

The confusion matrix based on the IDS evaluation report can be filled in as: Intrusion Attack No Intrusion Attack Alarm Sounded 45 (True Positive) 10 (False Positive) No Alarm5 (False Negative) 940 (True Negative)(4pt.). the accuracy of the IDS is 0.979, precision is 0.818, FPR is 0.010, and FNR is 0.10

Calculating the performance metrics of the IDS using the given confusion matrix, we have: Accuracy = (TP + TN) / (TP + FP + FN + TN)

= (45 + 940) / (45 + 10 + 5 + 940)

= 0.979

Precision = TP / (TP + FP)

= 45 / (45 + 10)

= 0.818

False Positive Rate (FPR) = FP / (FP + TN)

= 10 / (10 + 940)

= 0.010

False Negative Rate (FNR) = FN / (FN + TP)

= 5 / (5 + 45)

= 0.10

Therefore, the accuracy of the IDS is 0.979, precision is 0.818, FPR is 0.010, and FNR is 0.10

The performance of the IDS in detecting intrusions is good since it has a high accuracy value. The precision of 0.818 means that out of the 55 events classified as intrusions by the IDS, only 45 were actually intrusions. The false positive rate of 0.010 indicates that out of the 950 benign events, only 10 were wrongly classified as intrusions.

Finally, the false negative rate of 0.10 indicates that out of the 50 actual intrusions, only 5 were not detected by the IDS.

Determine the following properties of this soil: (i) void ratio (e); (ii) porosity (n); (iii) saturated density (Psat); (iv) dry density (Pdry); (v) saturated unit weight (Ysat); and (vi) density of soil solid grain

Answers

(i) Mass of water (Mw): 1.68 kg

(ii) Moisture content (w): w = 10.67%

(iii) Bulk density (Pb): 2022.72 kg/m³

(iv) Dry density (Pdry): 2329.03 kg/m³

(v) Volumes of air (Va) = 173.55 m³

water (VW) = 0.00168 m³

solid grain (Vs):   0.00778 m³

(vi) Air void ratio (Av):  99.42%

(vii) Void ratio (e): 22322.39

(viii) Porosity (n): 95.76%

(ix) Degree of saturation (S): 0.25

According to the given information:

(i) Mass of water (Mw):

The mass of water in the soil can be calculated as the difference between the mass of the moist soil and the mass of the oven-dry soil. So,

Mw = Mass of moist soil - Mass of oven-dry soil Mw

      = 17.8 kg - 16.12 kg Mw

      = 1.68 kg

(ii) Moisture content (w):

The moisture content of the soil is the mass of water in the soil divided by the mass of the dry soil, expressed as a percentage. So,

w = (Mass of water / Mass of dry soil) x 100%

w = (1.68 kg / (17.8 kg - 1.68 kg)) x 100%

w = 10.67%

(iii) Bulk density (Pb):

We calculated the bulk density earlier in response to your first question. It is given by:

Bulk density = Mass of soil / Volume of soil

Bulk density = 17.8 kg / 0.0088 m³

Bulk density = 2022.72 kg/m³

(iv) Dry density (Pdry):

The dry density of the soil is the mass of the solid grains in the soil per unit volume of dry soil. It can be calculated as follows:

Pdry = (Mass of solid grains / Volume of dry soil)

The mass of solid grains in the soil can be calculated by subtracting the mass of water from the mass of the oven-dry soil:

Mass of solid grains = Mass of oven-dry soil - Mass of water Mass of solid grains

                                  = 16.12 kg - 1.68 kg Mass of solid grains

                                  = 14.44 kg

The volume of dry soil can be calculated by dividing the mass of the oven-dry soil by the particle density of the soil:

The volume of dry soil = Mass of oven-dry soil / Particle density Volume of dry soil

                               = 16.12 kg / (2.6 x 1000 kg/m³)

Volume of dry soil  = 0.0062 m³

Therefore, the dry density of the soil is:

Pdry = Mass of solid grains / Volume of dry soil

Pdry = 14.44 kg / 0.0062 m³

Pdry = 2329.03 kg/m³

(v) Volumes of air (Va), water (VW), and solid grain (Vs):

We can calculate the volumes of air, water, and solid grains in the soil using the following equations:

Va = Pb / (γa x g)

VW = Mw / γw

Vs = (Pb - Mw/γw) / γs

where γa, γw, and γs are the densities of air, water, and solid particles, respectively, and g is the acceleration due to gravity.

Using the values γa = 1.2 kg/m³,

γw = 1000 kg/m³,

γs = 2600 kg/m³, and g = 9.81 m/s², we get,

Va  = 2022.72 / (1.2 x 9.81)

      = 173.55 m³

VW = 1.68 / 1000

      = 0.00168 m³

Vs = (2022.72 - 1.68/1000) / 2600

    = 0.00778 m³

(vi) Air void ratio (Av):

The air void ratio is the ratio of the volume of air to the total volume of the soil, expressed as a percentage. So,

Av = (Va / Vt) x 100%

Av = (173.55 m³ / (173.55 m³ + 0.00778 m³ + 0.00168 m³)) x 100%

Av = 99.42%

(vii) Void ratio (e): The void ratio is the ratio of the volume of voids to the volume of solid particles in the soil. So,

e = Va / Vs

e = 173.55 m³ / 0.00778 m³

e = 22322.39

(viii) Porosity (n):

The porosity is the ratio of the volume of voids to the total volume of the soil, expressed as a percentage. So,

n = (Va / Vt) x 100%

n = (173.55 m³ / (173.55 m³ + 0.00778 m³ + 0.00778 m³)) x 100%

n = 95.76%

(ix) Degree of saturation (S):

The degree of saturation is the ratio of the volume of water to the volume of voids in the soil, expressed as

(b) Soil properties for saturated soil with 25% moisture content and specific gravity of 2.69:

(i) Void ratio (e): We can calculate the void ratio as:

e = w / (1 - w) x Gs

Where w is the moisture content, and Gs is the specific gravity of the soil.

e = 0.25 / (1 - 0.25) x 2.69

e = 0.336

(ii) Porosity (n): The porosity can be calculated as:

n = e / (1 + e)

n = 0.336 / (1 + 0.336)

n = 0.25

(iii) Saturated density (Psat):

The saturated density can be calculated using the formula:

Psat = Gs x γw / (1 + e x (Gs - 1))

Where γw is the density of water, which is 1000 kg/m³.

Psat = 2.69 x 1000 / (1 + 0.336 x (2.69 - 1))

Psat = 2126.81 kg/m³

(iv) Dry density (Pdry):

The dry density can be calculated using the formula:

Pdry = Psat / (1 + w)

Pdry = 2126.81 / (1 + 0.25)

Pdry = 1701.45 kg/m³

(v) Saturated unit weight (Ysat):

The saturated unit weight is the weight of the soil per unit volume, including both solids and pores.

It can be calculated using the formula:

Ysat = Psat x g

Where g is the acceleration due to gravity.

Ysat = 2126.81 x 9.81

Ysat = 20898.41 N/m³

(vi) Density of water-saturated soil (Psub):

The submerged density can be calculated using the formula:

Psub = Psat - γw

Psub = 2126.81 - 1000

Psub = 1126.81 kg/m³

Answers

Closures and caps are commonly prepared by all of the above processes. Closures and caps are used for bottles, jars, and tubes in packaging applications. The closure, cap, or lid is a vital component of the packaging that keeps the contents of the container safe and secure. There are various types of closures and caps, including screw caps, child-resistant closures, and flip-top caps.

Closures and caps are made using different processes, and the selection of the manufacturing method depends on the type of closure required. The three primary manufacturing processes for closures and caps are injection molding, injection blow molding, and extrusion blow molding.Injection molding is a manufacturing process that involves melting plastic and injecting it into a mold.

The mold is then cooled and removed to form the final product. Injection molding is commonly used to make closures and caps that have complex shapes, such as screw caps. The process is fast, efficient, and produces high-quality parts.Extrusion blow molding is another manufacturing process that is commonly used to make closures and caps. The process involves melting plastic and extruding it into a tube or parison.

The parison is then placed in a mold, and compressed air is blown into it to form the final product. Extrusion blow molding is used to make caps and closures that are hollow or have a simple shape.Injection blow molding is similar to extrusion blow molding, but the process involves injecting plastic into a mold instead of extruding it. Injection blow molding is used to make closures and caps that have a more complex shape than extrusion blow molding.
