Secure ID-based Verifiably Encrypted Signature without Random Oracles
SU Li-wen · 2011
Verifiably encrypted signature can be used in secure electronic transactions.We presented the first efficient identity-based verifiably encrypted signature scheme which has the properties of verifiability and recoverability.We gave a security model with precise definitions and showed that the scheme is secure under the computational Bilinear Diffie-Hellman assumption without random oracles.
