Abstract: A directed signature allows only a designated verifier to check the validity of the signature, and any third party can verify the signature with the help of the designated verifier or the signer as well. Directed signature schemes are used in some special situations involving signature privacy. This work present a new directed digital signature scheme in a non-commutative group over group ring, the security of the proposed scheme based on the difficulty of the discrete logarithm problem DLP and the factorization search problem FSP. The scheme is very efficient since it requires only minimal ...
