Abstract. Formal methods have been extensively applied to the certification of cryptographic protocols. However, most of these works make the perfect cryptography assumption, i.e....
Abstract. Proxy signature schemes allow an original signer to delegate his signing rights to a proxy signer. Most proxy signature schemes have succeeded for proxy delegations and t...
The notion of strong designated verifier signature was put forth by Jakobsson, Sako and Impagliazzo in 1996, but the formal definition was defined recently by Saeednia, Kremer and...
Constructing practical and provably secure group signature schemes has been a very active research topic in recent years. A group signature can be viewed as a digital signature wit...
Abstract. We propose a variant of the “bonsai tree” signature scheme, a latticebased existentially unforgeable signature scheme in the standard model. Our construction offers ...
