- Encryption Matrices are commonly used to encrypt data. Here is a simple form such an encryption can take. First, we represent each letter in the alphabet by a number, so let us take = 0, A = 1, B = 2, and so on. Thus, for example, "ABORT MISSION" becomes [1 2 15 18 20 0 13 9 19 19 9 15 14]. To encrypt this coded phrase, we use an invertible matrix of any size with integer entries. For instance, let us take A to be the 3 2 2 x 2 matrix 4 1 We can first arrange the coded sequence of numbers in the form of a matrix with two rows (using zero in the last place if we have an odd number of characters) and then multiply on the left by A. 3 2 1 15 20 13 19 9 14 Encrypted Matrix = 4 1 2 18 0 9. 19 15 0 7 81 60 57 95 57 42 = 6 78 80 61 95 51 56 which we can also write as [7 6 81 78 60 80 57 61 95 95 57 51 42 56]. To decipher the encoded message, multiply the encrypted matrix by A1. The following exercise uses the above matrix A for encoding and decoding. Use the matrix A to encode the phrase "GO…Hi! This is not a graded question I just need it for my reviewer. Thanks! 2.Recall that a public-key cryptosystem consists of three functions: A key generator G, an encryption function E, and a decryption function D. Any user, say Alice (A), can use the key generator to generate a key pair (PKA, SKA), in which PKA is Alice’s public key, and SKA is her secret key; she can then publish her name and public key in a directory. Subsequently, anyone who wants to send a private message x to Alice can look up PKA in the directory, compute a ciphertext y ←− E(x, PKA), and send y to Alice over an open line. Only Alice can compute x ←− D(y, SKA), because only she knows the decryption key SKA that corresponds to encryption key PKA. Note that there is no need for a key-distribution center, as there is when one is using a symmetric-key cryptosystem, but there is a need for public-key directories. a) What is a public-key certificate? What is the problem with public-key directories that certificates…Below is an example of key generation, encryption, and decryption using RSA. Look at the example, then fill in the blanks to indicate what each part is or answer the question. You do not have to do any math for this. Here are the words to select from to fill in the blanks.

- Bob has sent his secret number m to Alice via secure RSA encryption. Break his ciphertext to find m. To factorize the number N, you can use the program. Alice's public key (e, N) = (17, 29329): Bob's ciphertext c = 16469The chef is getting bored with the recent lockdowns caused by the coronavirus epidemic. After some time he started learning cryptography. He is very excited to see the different types of keys used in cryptography and decides to invent a new type of key. First, Chef created a sequence of integers A1,A2,......An that lie between 1 and M inclusive. After many sleepless nights, he decided that his key would be the LCM of this sequence, but he is not satisfied - he wants to make his key as big as possible. To do this, he wants to append exactly one more integer to the sequence. This integer must also be between 1 and M, inclusive. Help the chef to maximize the key. Find the integer that Chef should append to the sequence so that the key (LCM of the elements of the resulting sequence) is as large as possible. If there are multiple solutions, choose the smallest of the integers to connect that maximizes the LCM.Input Note: please answer this in java language only. 1 32 212 Output 1Determine the decibel values of thermal noise power (N) and thermal noise power density (No) given the following: T=298 degrees Kelvin, B = 20MHz.

- Bob sent Alice an encrypted message. The message consists of 3 words. In each word, Bob encoded the letters as follows: A = 01, B = 02, C = 03, ., Z = 26. The he wrote the codes next to each other to form a number that represent the word. For example, the word "WE" is encoded as: 2305 since it consists of 2 letters W=23 and E=05. After encoding, Bob encrypted each encoded word with RSA using Alice public key(pq, e) where p=100000007, q=10000019, e=13.
