Suppose thatf: {0, 1}mΖ {0 1}mis a preimage resistant

bijection. Defineh: {0, 1}2mΖ {0, 1}mas follows. GivenxOE {0, 1}2m, writex=x||x

wherex, x OE {0, 1}m. Then define

h(x) =f(x'!x''). where is XOR operationProve thathis not second

preimage resistant.

could you please help me to prove that, any help would be appreciated

Thanks,
