WebQuestion: - Problem 4 Let E: {0,1}k > {0,1}2n + {0,1}2n be a block cipher and let Te denote the time to compute E or E-1. Let K be the key-generation algorithm that returns a random k-bit string as the key K. Define encryption algorithm E, for all inputs K € {0,1}k and M € {0,1}2n, as follows: Alg E(K, M) M[1]M[2] + M ; R[1] << {0,1}" ; R[2] — 1" @ R[1] M[2] C[1] – WebPort 7927 Details.
