What is the definition of stream cipher? A. Cryptography wherein two keys are used: one to encrypt the message and another to decrypt it B. A cryptographic method in which someone chooses a number by which to shift each letter of a text in the alphabet and substitute the new letter for the letter being encrypted C. A form of cryptography that encrypts the data as a stream, one bit at a time D. A method other than brute force to derive a cryptographic key

Answers

Answer 1

Answer:

C. A form of cryptography that encrypts the data as a stream, one bit at a time

Explanation:

Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.

In Cyber security, encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext.

Typically, an information or data that has been encrypted can only be accessed and deciphered by an authorized user.

Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.

A stream cipher is a form of cryptography that is typically designed to encrypt a stream of data, one bit at a time. Thus, each bit corresponds to series of information within a data stream and they are encrypted one after the other.

The router is physically located in a server room that requires an ID card for access. You backed up the router configuration to a remote location in an encrypted file. You access the router configuration interface from your notebook computer using a Telnet client with the username admin and the password admin. You used the MD5 hashing algorithm to protect the password. What should you do to increase the security of this device

Answers

Answer: Use an SSH client to access the router configuration.

Change the default administrative username and password

Explanation:

Based on the information given, in order to increase the security of the device, it's vital to use an SSH client to access the router configuration. The SSH client refers to the program that helps in establishing an authenticated and secure SSH connections to the SSH servers. It's vital for operating network services securely over a network that's unsecured.

Also, the default administrative username and password should be changed to a more secure username and password which can't be easily known by a third party.

Email encryption is the encryption and authentication of an email to protect the message therein from being read by any person other than the intended recipients. Thus, it protects the email from hacking or invasion by a third party.

Basically, when the message is signed with the sender's private key, the receiver can verify its authenticity using the sender's public key.

Also, encrypting the email message with the receiver's public key provides confidentiality.

In this scenario, the most likely explanation for this result is that the symmetric encryption key had been compromised.

A host is on the 192.168.146.0 network that has a subnet mask of 255.255.255.0. The binary value of the host portion is 11010101. What is the decimal value of the host portion of the address?

Answers

Answer:

213

Explanation:

The given parameters are;

The network on which the host is on = 192.168.146.0

The subnet mast = 255.255.255.0

The binary value of the host portion = 11010101

To convert the binary value to decimal value, we proceed by multiplying each of the digits of the binary value by the corresponding power of 2, from the left to right, starting from a power of 0, and sum the result, as follows;

(11010101)₂ = (1×2⁷ + 1×2⁶ + 0×2⁵ + 1×2⁴ + 0×2³ + 1×2² + 0×2¹ + 1×2⁰)₁₀

1×2⁷+1×2⁶+0×2⁵+1×2⁴+0×2³+1×2²+0×2¹+1×2⁰= 128+64+0+16+4+1 = 213

∴ (11010101)₂ = (213)₁₀

The decimal value of 11010101 is 213.

Data stored on physical storage devices must do what before the processor can access it? Be converted to binary Be written to the hard drive Go into short-term memory Go from volatile to nonvolatile memory

Answers

Answer:

Go into short-term memory

Explanation:

Data stored on physical storage devices must go into short-term memory before the processor can access it.

This is because, physical storage devices are secondary memory which store information for a long time. The CPU does not work directly with secondary memory but with primary or short term memory. Since the CPU works mainly with short term memory, information in physical storage or secondary memory has to go into short term memory for the CPU to be able to process it.

So, data stored on physical storage devices must go into short-term memory before the processor can access it.

pre convert single digits, or sometimes parts of a sum, then sum up. like this:

1.) 2³+2²+2^1+2^0 = 8+4+0+1 = 13

2.) 512 + 0 + 128 + 0 + 0 + 16 + 0 + 4 + 2 + 0 = 1010010110

you just need to know what the powers of two are, then you know how to convert numbers.

like 100 = 4 and 1 = 1 then 101 = 4 + 1 and in the other direction just take chunks of 5 until theres nothing left, but care not to overshoot the sum

5 = 2² + 0 + 2^1 = 101 in base2

the zeros are for the order, every time I would overshoot, it's a zero.

3.) 16 + 2 + 19 = 37

4.) 8² is 64, or (100)base8

8³ or 1000 would already overshoot, so let's see what we can do with the smaller value of a digit in base8, 8² = 64

we can 8 different digits (0 to 7) in base8

7x8^2 + 2*8^1 + 5*8^0

448 + 16 + 5

= (725)base8

The montage language and high programming languages such as FORTRAN, COBOL, have been used in this generation. The computers used batch processing and operating system multi-programming.

A memory is like the brain of human beings. It is used for storing information and instructions. Computer memory is the storage space on the computer that processes data and saves instructions for processing.

Computers work on the garbage-in, garbage-out concept. Comment

Answers

Stands for "Garbage In, Garbage Out." GIGO is a computer science acronym that implies bad input will result in bad output.

Because computers operate using strict logic, invalid input may produce unrecognizable output, or "garbage." For example, if a program asks for an integer and you enter a string, you may get an unexpected result. Similarly, if you try to open a binary file in a text editor, it may display unreadable content.

GIGO is a universal computer science concept, but it only applies to programs that process invalid data. Good programming practice dictates that functions should check for valid input before processing it. A well-written program will avoid producing garbage by not accepting it in the first place. Requiring valid input also helps programs avoid errors that can cause crashes and other erratic behavior.

NOTE: Because the related terms FIFO and LIFO are pronounced with a long "i," GIGO is typically pronounced "guy-go" (not gih-go). This also helps avoid confusion with the prefix "giga," which is pronounced with a soft "i."
