Consider the following proposal to prevent DES from exhaustive key search under a known-plaintext attack. The secret key is k=k{1,k2}, where k1 is in (0,1) ^56 and k2 is (0,1) ^64. Let m be in (0,1) ^64 be the plaintext message. Encryption is defined as follows Ek(m)=DESk1(m) XOR k2 (a) Show that this proposal does not increase the work needed to break the encryption scheme E using brute force (exhaustive) search (that is, approximately 2^56 DES operations are still sufficient)....

1. Bob wants to use DES to make a secured communication with Alice using DES key ‘Kb’ to encrypt and decrypt data. Bob uses PKI method to distribute the DES key to Alice. If Alice private key is ‘Kpa’, and her public key is ‘Kpb’. Please describe the process that Bob can send his DES key ‘Kb’ to Alice securely. 2. You receive a message that was encoded using a block encoding scheme with the encoding matrix M=3275 Verify by...

Encipher each plaintext trigraph code by computing (Plaintext trigraph code)Public Key, dividing the result by the Modulus and taking the remainder. Okay so the trigraph key is 2723 and the public key is 97 and the modulus is 50657. Literally every calculator i use says the number is too large. I am so confused. These are the numbers what is the problem. Is this the wrong formula the teacher gave us this formula. I am so confused.

4.18 Using S-DES (see Appendix G on Blackboard), decrypt the string (10100010) using the key (0111111101) by hand. Show intermediate results after each function (IP, FK, SW, FK, IP-1). Then decode the first 4 bits of the plaintext string to a letter and the second 4 bits to another letter where we encode A through P in base 2 (i.e., A = 0000, B = 0001, …, P = 1111). Hint: As a midway check, after the application of SW,...
