Detailed explanation-1: -The Advanced Encryption Standard (AES) is an algorithm that uses the same key to encrypt and decrypt protected data. Instead of a single round of encryption, data is put through several rounds of substitution, transposition, and mixing to make it harder to compromise.
Detailed explanation-2: -AES is based on a design principle known as a substitution–permutation network, and is efficient in both software and hardware. Unlike its predecessor DES, AES does not use a Feistel network. AES is a variant of Rijndael, with a fixed block size of 128 bits, and a key size of 128, 192, or 256 bits.
Detailed explanation-3: -The AES algorithm is widely used in a variety of applications, including wireless security, processor security, file encryption, and SSL/TLS. AES encryption is used regularly by federal government departments as well as non-government entities, commercial firms, and organizations, to secure sensitive data.
