Sequential Aggregate Signatures from Trapdoor Permutations
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...

Fine-grained forward-secure signature schemes without random oracles
We propose the concept of fine-grained forward-secure signature schemes. Such signature schemes not only provide non-repudiation w.r.t. past time periods the way ordinary forward-...

A Group Signature Scheme from Lattice Assumptions
Group signature schemes allow users to sign messages on behalf of a group while (1) maintaining anonymity (within that group) with respect to an observer, yet (2) ensuring traceab...

On the Key Exposure Problem in Chameleon Hashes
Chameleon signatures were introduced by Krawczyk and Rabin, being non-interactive signature schemes that provide non-transferability. However, that first construction employs a c...
