高级加密标准 Advanced Encryption Standard

(重定向自Rijndael)
在AddRoundKey步骤中,将每个状态中的字节与该回合密钥做异或(⊕)。
在SubBytes步骤中,矩阵中各字节被固定的8位查找表中对应的特定字节所替换,S; bij = S(aij).

高端加密标准英语:Advanced Encryption Standard,缩写:AES),在密码学中又称Rijndael加密法,是美国联邦政府采用的一种区块加密标准。这个标准用来替代原先的DES,已经被多方分析且广为全世界所使用。经过五年的甄选流程,高端加密标准由美国国家标准与技术研究院(NIST)于2001年11月26日发布于FIPS PUB 197,并在2002年5月26日成为有效的标准。2006年,高端加密标准已然成为对称密钥加密中最流行的算法之一。

该算法为比利时密码学家Joan Daemen和Vincent Rijmen所设计,结合两位作者的名字,以Rijndael为名投稿高端加密标准的甄选流程。(Rijndael的发音近于"Rhine doll")

Advanced Encryption Standard 高级加密标准

(重定向自Rijndael)
In the SubBytes step, each byte in the state is replaced with its entry in a fixed 8-bit lookup table, S; bij = S(aij).
In the ShiftRows step, bytes in each row of the state are shifted cyclically to the left. The number of places each byte is shifted differs for each row.
In the MixColumns step, each column of the state is multiplied with a fixed polynomial c(x).

The Advanced Encryption Standard (AES), also known as Rijndael (its original name), is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001.

AES is based on the Rijndael cipher developed by two Belgian cryptographers, Joan Daemen and Vincent Rijmen, who submitted a proposal to NIST during the AES selection process. Rijndael is a family of ciphers with different key and block sizes.
