1. In SHA-3, which step function does the operation L[2,3] <- L[2,3] XOR NOT(L[3,3]) AND L[4,3] represent? a) Theta b) Rho c) Pi d) Chi AnswerAnswer: d [Reason:] The above operation represents the chi step function. 2. In SHA-3, which function does the operation L[2,3]<- C[1] XOR L[2,3] XOR ROT(C[3],1) represent? a) Theta b) Rho…
