1.	In _____________ a sequence of actions is carried out on this block after a block of plain-text bits is chosen for generating a block of cipher-text bits.(a) Block Cipher(b) One-time pad(c) Hash functions(d) Vigenere CipherI have been asked this question during an online interview.This interesting question is from Cryptography in chapter Cryptography in Security of Cyber Security
Answer» Right OPTION is (a) Block Cipher For explanation I would say: In block cipher, a SEQUENCE of actions is carried out on this block after a block of plain-text bits is CHOSEN for generating a block of cipher-text bits. Blocks in these have fixed number of bits.
