Which of the following refers to a symmetric key cipher which operates on fixedlength groups of bits with an unvarying transformation?
- stream cipher
- block cipher
- check cipher
- string cipher
- None of the choices.
Explanation:
In cryptography, a block cipher is a symmetric key cipher which operates on fixed-length groups of bits, termed blocks, with an unvarying transformation.
A stream cipher, on the other hand, operates on individual digits one at a time.
