Title: Provably Secure Signcryption Scheme Based on Elliptic Curve
Abstract: A signcryption scheme can realize signature and encryption simultaneously,and its cost is smaller than the sum of signature and encryption.However,most signcryption schemes do not have strict security proof.This paper proposes a signcryption scheme based on difficult problems of elliptic curve group.The scheme is efficient and only needs one pair operation.It proves that the scheme is semantic secure and unforgeable in the standard model.Moreover,the scheme has non-repudiation,forward security and public verification.
