more general view of Schnorr’s protocol that we saw last lecture: a Sigma protocol for an NP relation R is an interactive protocol, in which the prover’s and the verifier’s inputs are x, y and y respectively, where (x, y) 2 R, and the protocol consists of three messages: The prover sends the first message u, called a commitment. The verifier choose...
The Fiat-Shamir heuristic, that we’ve seen for Schnorr’s protocol, can be applied to any Sigma protocol to obtain Non-interactive zero-knowledge proofs in the Random Oracle model.
we obtain a signature scheme, in which sk Æ (x) and pk Æ (y). We can then prove the security of the resulting signature scheme (existenital unforgeability) in the random oracle model, by showing that we can use an adversary that forges a signature to construct another adversary that breaks the identification protocol.
In any public-key encryption scheme, one can use t-out-of-n Shamir secret sharing to share the secret decryption key between n servers. Then, anyone can encrypt a message to the servers using the public key, but it takes a coalition of t servers to decrypt a ciphertext: t servers recombine the secret key and decrypt. This creates a single point of ...
