2.6 For each of the following encryption schemes, state whether the scheme is perfectly secret. Justify your answer in each case. (a) The message space is M = {0, ,4). Algorithm Gen chooses a uniform key from the key space f0,...,5. Enck(m) returns k+m mod 5], and Deck(c) returns c- kmod 5 (b) The message space is M E (0,1] the last bit of m is 0). Gen chooses a uniform key from (0,1)Enck(m) returns cipher- text me(?0), and Deck (c) returns c?(k110)
