Research On Aes And Analysis Of It'S Security
2011 INTERNATIONAL CONFERENCE ON FUTURE COMPUTER SCIENCE AND APPLICATION (FCSA 2011), VOL 2(2011)
摘要
AES is a kind of symmetric block cipher arithmetic. AES is an iterative cipher based on finite field computation. In each round of AES encryption arithmetic, all operations are ShiftRows Transformation and MixColumns Transformation except AddRoundKey. Using lookup table can improve the performance. The security of AES is discussed. The capability of attacks resistance to some kinds of cipher attack means, weak keys and relativity of keys are discussed.
