Improved Signeryption Scheme with Public Verifiability
Signcryption is an asymmetric method that provides simutaneously both message confidentiality and unforgeability at a low computational and communication overhead.Signcryption scheme can achieve signature authentication and encryption transmission simultaneously in a single protocol,it effectively prevents mutual cheating in message transmission.To solve the problems of no forward security and public verifiability.an improved signcryption scheme on elliptic curve is proposed.Proofs of security are given using the hypothesis of elliptic curve discrete logarithm problem and the ellitic curve DHP.The scheme not only has the properties of confidentiality,authentication,unforeability,integrit y and non-repudiation but also has the properties of public verifiability and forward security.
