One-way property strategy and improvement of key generation algorithm of Rijndael
Fang Liu · Journal of Jilin University · 2009
The key generation algorithm of Rijndael and Mars was introduced.By comparison with Data Encryption Standard(DES),the concept to design new key generation algorithm of block ciphers was analyzed.The weaknesses of the key generation design of Rijndael were investigated,and a new designing strategy was developed,which can be used to improve the key generation algorithm.Analysis shows that such improvement can enhance the safety of the original algorithm without reducing its efficiency.
