Advanced Encryption Standard (AES) is based on
(A) Asymmetric key algorithm
(B) Symmetric key algorithm
(C) Public key algorithm
(D) Key exchange
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.
