This is a two-party primitive in which a sender (Alice) gets two uniformly random bits b 0, b 1 and a receiver (Bob) gets a uniformly random choice bit c and b c. Bob remains ignorant about b ¯ c. On the other hand, Alice cannot learn the choice bit c. Webb1-out-of-n oblivious transfer protocol in JavaScript. Protocol. To create 1-out-of-N, we use log2(N) 1-out-of-2 oblivious transfers of random bits to create log2(N) random strings. Each secret is masked with one of these strings (by XOR) and the receiving party picks one after which the sender reveals all the masked secrets. prodigy apk download
