为了降低简单能量算法、差分能量分析对分组密码攻击的可能性,针对分组密码芯片能量消耗情况,实施了对密码芯片的模块保护设计。通过对密码芯片中算法的线性部分与非线性部分进行抗能量攻击的模块保护设计,提高了密码芯片抗能量攻击性能。
For the fact that cryptography chip exits energy consumption, the protection methods have been designed for against sample power attack, ifferential power attack. To avoid the power attack of block cipher, a module protected design approach is put forward to by protecting linear and non, linear module of block cipher algorithm respectively. This approach can resist power analysis attack effectively.
