National Institute of Standards and Technology (NIST) in 2001. The Advanced Encryption Standard ( AES), also known by its original name Rijndael ( Dutch pronunciation: ), is a specification for the encryption of electronic data established by the U.S. Related-key attacks can break AES-256 and AES-192 with complexities 2 99.5 and 2 176 in both time and data, respectively. For biclique attacks on AES-192 and AES-256, the computational complexities of 2 189.7 and 2 254.4 respectively apply. įor AES-128, the key can be recovered with a computational complexity of 2 126.1 using the biclique attack. Attacks have been published that are computationally faster than a full brute-force attack, though none as of 2013 are computationally feasible.
