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

bijection. Defineh: {0, 1}2mÆ {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,
