ISRO | ISRO CS 2009 | Question 7

  • Last Updated : 04 Jun, 2018

Advanced Encryption Standard (AES) is based on

(A) Asymmetric key algorithm
(B) Symmetric key algorithm
(C) Public key algorithm
(D) Key exchange

Answer: (B)

Explanation: AES is a symmetric key algorithm i.e. same key is used for encryption and decryption process.

The AES replaced the DES with new and updated features-
Block encryption implementation.
128-bit group encryption with 128, 192 and 256-bit key lengths.
Symmetric algorithm requiring only one encryption and decryption key.
AES design is based on a substitution-permutation network (SPN).
Data security for 20-30 years.
Easy overall implementation.

So, option (B) is correct.
