A New digital signature scheme based on Stepwise Triangular Scheme (STS) is proposed. The proposed trapdoor has resolved the vulnerability of STS and secure against both Gr¨obner ...
An aggregate signature scheme (recently proposed by Boneh, Gentry, Lynn, and Shacham) is a method for combining n signatures from n different signers on n different messages int...

In 2004, Abe et al. proposed a threshold signer-ambiguous signature scheme from variety of keys. Their scheme is a generalized case of the ring signature scheme, and it allows the ...
We provide an alternative method for constructing lattice-based digital signatures which does not use the “hash-and-sign” methodology of Gentry, Peikert, and Vaikuntanathan (ST...
Abstract. Chameleon signatures are based on well established hashand-sign paradigm, where a chameleon hash function is used to compute the cryptographic message digest. Chameleon s...
