Abstract

Abstract

Utilizing the Shim's identity-based signature scheme, a new identity-based verifiably encrypted signature scheme is proposed. As a building block of the fair exchange protocol, this approach does not use any zero-knowledge proofs to provide verifiability, it avoids most of the costly computations. Compared to the previous identity-based verifiably encrypted signature schemes, the proposed scheme is more efficiency. The performance analysis results show that the scheme is provably secure in the random oracle model under the CDH problem assumption.
