Trevisan has shown that constructions of pseudo-random generators from hard functions (the Nisan-Wigderson approach) also produce extractors. We show that constructions of pseudo-r...

Chameleon signatures were introduced by Krawczyk and Rabin, being non-interactive signature schemes that provide non-transferability. However, that first construction employs a c...
Abstract. We introduce a new cryptographic problem called time capsule signature. Time capsule signature is a ‘future signature’ that becomes valid from a specific future time...
At EuroCrypt’99, Paillier proposed a new encryption scheme based on higher residuosity classes. The new scheme was proven to be one-way under the assumption that computing N-resi...
