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...
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 ...

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...

Their "free-XOR" technique has proven very popular, and has been shown to improve performance of garbled-circuit protocols by up to a factor of 4. Kolesnikov and Schneider proved security of their approach in the random oracle model, and claimed that (an unspecified variant of) correlation ...
