Abstract |
In this paper, we propose a strong designated verifier proof signature scheme for an ad-hoc group and discuss its security properties. The proposed scheme provides a way that leaks authoritative secrets to only a designated person anonymously by one of the ad-hoc group members and no one knows that the secret is from a group member or the recipient, except the recipient. This group is called a ring. At first we propose a strong designated verifier proof signature without using hash functions for one signer and then we propose the same scheme for an ad-hoc environment. |
