This paper introduces the free-XOR technique for standard garbled circuits to card-based garbled circuits. It is unnecessary to prepare a garbled table for XOR gates. The number of cards is reduced to \\(8g_1+2g_2+2n\\) , where \\(g_1\\) is the number of gates other than XOR ...

Free XOR 姚的混淆电路在构建的时候,无论是什么 1-out-of-2 逻辑门(与、或、异或、与非、或非)都需要计算 4 4 4个密文。Kolesnikov 等人针对异或门的特殊性质,给出了不必构造混淆真值表的异或门(Free XOR)的构造。同时,非门本身的计算就是“免费的”,交换label 即可。 对于异或门的观察如下:假设三根线分别...

We show that the free-XOR technique cannot be proven secure based on correlation robustness alone; somewhat surprisingly, some form of circular security is also required. We propose an appropriate definition of security for hash functions capturing the necessary requirements, and prove security of the...

pascal语言中xor是按位异或不是条件判断语句，1 xor 1=0, 0 xor 0=0, 1 xor 0=1, 0 xor 1=1.楼上几个说的都不对xor的确是异或 但可以作为条件之间的连接那么<条件> xor <条件>的值就相当于两个boolean变量作异或计算结果为true xor true = falsetrue xor false = truefalse xor true...
