Exercise 12: your opponent has invented a new stream cipher mode of operation for 128 bit key aes. he thinks that ofb could be improved by feeding back into the key port rather than the data port of the aes chip.
Exercises Meeting 9 14 Pdf Cryptography Encryption The document contains 26 exercises related to cryptography and cipher techniques: exercise 1 asks to compute the gcd of two numbers using euclid's and extended euclid's algorithms. exercises 2 4 involve encrypting decrypting messages using vigenere and simple substitution ciphers. Second, we observe that if the oracle o of d′ is the function f described in the exercise then, for all k, we have that pr(d′fk(·)(1n) = 1) = 1 because k ∨ 1n is always equal to 1n.
