The output of the pseudorandom bit generator in a stream cipher structure is called a keystream, which is combined with the plaintext using the bitwise exclusive-OR operation.
Explanation:
In a stream cipher structure, the key is input to a pseudorandom bit generator, which produces a keystream of apparently random 8-bit numbers. The keystream is then combined with the plaintext stream one byte at a time using the bitwise exclusive-OR operation. This operation produces ciphertext that is as long as the plaintext and is completely dependent on the key and the keystream. The security of a stream cipher relies on the unpredictability and randomness of the keystream, which should be indistinguishable from a truly random sequence.

what are the correct order of steps that ssl uses in its coding process? group of answer choices fragmentation, compression, encryption encryption, compression, fragmentation compression, fragmentation, encryption fragmentation, encryption, compression
It is important to note that SSL has been superseded by TLS (Transport Layer Security) and is no longer considered a secure protocol. TLS uses a similar process for encrypting data, but with different encryption algorithms and other improvements to security.
The correct order of steps that SSL (Secure Sockets Layer) uses in its coding process is:
Fragmentation: The data is divided into small fragments so that it can be transmitted easily over the network.
Encryption: Each fragment is encrypted using a symmetric encryption algorithm such as AES, 3DES, or RC4. The encryption key is generated using a public-key encryption algorithm such as RSA or Diffie-Hellman.
Compression: The encrypted fragments are compressed using a compression algorithm such as zlib to reduce the size of the data being transmitted.
Transmission: The compressed and encrypted fragments are transmitted over the network.
Reception: The receiver receives the compressed and encrypted fragments and performs the reverse process - decompressing the fragments, decrypting them, and reassembling them into the original data.

in this exercise you will complete a class that implements a shopping cart as an array of items. the file item.java contains the definition of a class named item that models an item one would purchase. an item has a name, price, and quantity (the quantity purchased). the file shoppingcart.java implements the shopping cart as an array of item objects. 1. complete the shoppingcart class by doing the following: a. declare an instance variable cart to be an array of items and instantiate cart in the constructor to be an array holding capacity items. b. fill in the code for the increasesize method. your code should be similar to that in listing 7.8 of the text but instead of doubling the size just increase it by 3 elements. c. fill in the code for the addtocart method. this method should add the item to the cart and update the totalprice instance variable (note this variable takes into account the quantity). d. compile your class.
Here's the completed code for the Shopping Cart class:
public class ShoppingCart {
private Item[] cart;
private int totalItems;
private double totalPrice;
private int capacity;
public ShoppingCart(int capacity) {
cart = new Item[capacity];
totalItems = 0;
totalPrice = 0.0;
this.capacity = capacity;
}
private void increaseSize() {
Item[] newCart = new Item[capacity + 3];
for (int i = 0; i < totalItems; i++) {
newCart[i] = cart[i];
}
cart = newCart;
capacity = capacity + 3;
}
public void addToCart(Item item) {
if (totalItems == capacity) {
increaseSize();
}
cart[totalItems] = item;
totalItems++;
totalPrice += item.getPrice() * item.getQuantity();
}
}
The completed Shopping Cart class has an instance variable cart which is an array of Item objects. In the constructor, the cart array is instantiated to be an array holding capacity items.
The instance variable totalItems keeps track of the number of items currently in the cart, while totalPrice keeps track of the total price of all items in the cart. The instance variable capacity is used to determine when the cart array needs to be increased in size.
The increaseSize method creates a new array with a capacity of 3 elements greater than the current cart array. The elements in the current cart array are then copied to the new array, and the cart variable is set to reference the new array.
The addToCart method adds the specified item to the cart array. If the cart array is already at capacity, the increaseSize method is called to increase its capacity. The totalItems and totalPrice instance variables are then updated accordingly.

Since the TTL field has to be recalculated at every router, the ___ ___ field must also necessarily be modified.
Since the TTL (Time-to-Live) field has to be recalculated at every router, the IP header checksum field must also necessarily be modified.
In an IP packet, the TTL field is used to prevent packets from endlessly circulating in a network. At each router, the TTL value is decremented by one. When the TTL reaches zero, the packet is discarded to avoid loops. The IP header checksum field is used to detect errors in the IP header. It is a 16-bit value calculated using the entire IP header.
Since the TTL value changes at each router, it becomes necessary to recalculate the IP header checksum as well. This is because the checksum is based on the entire IP header, including the TTL field. If the checksum is not recalculated, the packet may be considered corrupted, leading to data loss or communication issues.
In summary, when the TTL field is recalculated at each router, the IP header checksum must be modified to maintain accuracy and ensure reliable communication within the network. This process helps avoid packet loops and ensures that any errors in the IP header are detected and corrected promptly.

Deduplication works with compression and __________to optimize capacity efficiency.
A) erasure coding
B) inline compression
C) sequential writes
D) post process
Deduplication works with compression and a) erasure coding to optimize capacity efficiency.
In data storage systems, deduplication is a technique used to eliminate redundant data, ensuring that only unique data is stored. This process helps in reducing the storage space required and improves overall storage efficiency.
Compression is another method that works hand in hand with deduplication. It involves reducing the size of data by identifying and eliminating repetitive patterns within the data. This further enhances the storage efficiency of the system.
Erasure coding, on the other hand, is a data protection technique that divides data into multiple fragments and encodes them with additional parity data. This allows for the reconstruction of the original data in case any fragments are lost or corrupted. Erasure coding works together with deduplication and compression to ensure not only optimized storage capacity but also data integrity and fault tolerance.
In conclusion, deduplication, compression, and erasure coding work collectively to maximize capacity efficiency in data storage systems. These techniques contribute to reduced storage costs, better utilization of available resources, and enhanced data protection and resilience.

In programming, a loop often reads input from the user or from a file until a specific condition is met. The sentinel value is used to signal the end of the input and cause the loop to terminate.
For example, consider a program that reads a list of integers from the user until the user enters a sentinel value of -1 to indicate the end of the input. The program would use a loop to read the input values and check if each value is equal to the sentinel value. If the value is equal to the sentinel value, the loop would terminate, and the program would move on to the next step.
Sentinel values are often used in input validation and error handling to ensure that a program does not continue to run indefinitely or produce incorrect results due to unexpected input. By using a specific sentinel value to signal the end of input, a program can ensure that it processes only the intended input values and avoids errors or unexpected behavior.
