Motivated by privacy issues associated with dissemination of signed digital certificates, we define a new type of signature scheme called a `Universal Designated-Verifier Signatur...

Verifiably encrypted signature schemes (VES) allow a signer to encrypt his or her signature under the public key of a trusted third party, while maintaining public signature verifi...
Abstract. Several researchers have proposed the use of threshold cryptographic model to enable secure communication in ad hoc networks without the need of a trusted center. In this...
We propose a new computational complexity assumption from bilinear map, based on which we construct Verifier-Local Revocation group signatures with shorter lengths than previous on...
Abstract. We report on a case study in applying different formal methods to model and verify an architecture for administrating digital signatures. The architecture comprises seve...
