Describe Advanced Encryption Standard (AES)

Question

Examlex · Accepted Answer

The Answer is AES is a block cipher that uses the same key for both encryption and decryption. With AES, bits are encrypted in blocks of plaintext that are calculated independently, rather than a keystream acting across a plaintext data input stream. AES has a block size of 128 bits with three possible key lengths: 128, 192, and 256 bits as specified in the AES standard. For the WPA2/802.11i implementation of AES, a 128-bit key length is used. AES encryption includes four stages that make up one round. Each round is then iterated 10, 12, or 14 times depending upon the bit-key size. For the WPA2/802.11i implementation of AES, each round is iterated 10 times.
