两者加一起为模乘次数。 比如上面想求a##21,21用二进制表示为10101,所以该算法所需要模乘次数为(5-1)+(3-1)=6次。 但此算法未必是最优的,我们来看看如下例子: 想求a##441, 441用二进制展开为110111001,于是模乘次数应该是(9-1)+(6-1)=13次。 但我们可以用另外一种方式来求a##441, 441 = 21...

比如21=3*7，3和7是两个质数，所以φ(21)=(3-1)*(7-1)=12。2、同余式

Summary: Many applications of embedded devices require the generation of cryptographic secret parameters during the life cycle of the product. In such an unsafe context, several papers have shown that key generation algorithms are vulnerable to side-channel attacks. This is in particular the case of...
