Question

RC4 algorithm uses the concept of Block Cipher System.

(a) True

(b) False

The question was asked in unit test.

I need to ask this question from RC4 and RC5 in chapter Pseudorandom Number Generation and Stream Ciphers and More Block Ciphers of Cryptograph & Network Security

Answer 1

The correct choice is (b) False

To explain I would say: RC4 algorithm uses the concept of Stream Cipher and uses a “stream key”.
