The Advanced Encryption Standard (AES), invented by Joan Daemen and Vincent Rijmen, is the most widely used encryption algorithm in the world. AES’s predecessor was the Data Encryption Standard (DES). Unlike DES, AES uses a fixed block size of 128 bits and supports key lengths of 128, 192 and 256 bits. With AES, it is very difficult for an adversary to recover the plaintext from the ciphertext without knowing the encryption key. However, it is still vulnerable to side-channel attacks that can exploit information leakage from a cryptographic system through variations in power consumption or timing to obtain the cryptographic key.
