(a) True

(b) False

This question was addressed to me by my college professor while I was bunking the class.

Question is from Secure Hash Algorithms (SHA) in chapter Other Public Key Cryptosystems and Cryptographic Hash Functions of Cryptograph & Network Security

Answer 1

The correct answer is (b) False

The best I can explain: The larger the value of ‘r’, the greater the rate at which message bits are processed by the sponge construction. ‘r’ is referred to as bitrate.
