WebThree is known as the generator. If we raise three to any exponent x, then the solution is equally likely to be any integer between zero and 17. Now, the reverse procedure is hard. Say, given 12, find the exponent three needs to be raised to. This is called the discrete logarithm problem. And now we have our one-way function, easy to perform ... Web1. I assume we are in the case of , and we have , and we want to determine whether the order of is in fact . From Exercise 1.31, Silverman and Pipher: Let and let . Prove that either or else has order . (In addition, by remark 1.33, there are exactly primitive elements.) Naively, I would try to use the result of the exercise on the prime ...

WebMar 18, 2015 · We introduce and instantiate a new cryptographic primitive, called non-interactive distributed encryption, that allows a receiver to decrypt a ciphertext only if a minimum number of different senders encrypt the same plaintext. The new functionality can be seen as the dual of the functionality provided by threshold cryptosystems.
