| 摘要: |
| 使用能量攻击对MARS 和Rijndael进行了深入分析.结果表明:对于256,192和128比特密钥的MARS算法,能量攻击的复杂度平均分别为2288,2168 和 2116.对于256,192和128比特密钥的Rijndael算法,能量攻击的复杂度平均分别为2131,299和267.虽然攻击的复杂度实际上无法达到,但是此攻击方法大大降低了MARS 和Rijndae的密钥规模. |

| Abstract: |
| MARS and Rijndael are analyzed by using power attack. It is shown that the complexities on MARS are 2208, 2168 and 2116 for 256, 192 and 128 bits key respectively, the complexities on Rijndael are 2131, 299 and 267 for 256, 192 and 128 bits key respectively. Although the complexities are too big to implement, the approach presented in this paper reduces greatly the key size of MARS and Rijndeal. |
