Question

The 8 × 8 hash matrix holds values of size

(a) 16 bits

(b) 32 bits

(c) 8 bits

(d) 4 bits

I got this question by my school principal while I was bunking the class.

The query is from Whirlpool Algorithm in chapter Message Authentication Codes, Whirlpool Algorithm and Key Management and Distribution of Cryptograph & Network Security

Answer 1

Right option is (c) 8 bits

The best I can explain: 8 × 8 × 8 = 512 bits. 512 bits is the size of the message block. Thus we require 8 bits only.
