Signcryption scheme with public verifiability and forward security
一个可公开验证且前向安全的签密方案

This paper improved signcryption schemes and as a result,proposed a public verifiable signcryption schemes with forward secrecy.In the improved schemes,the attacks which obtain the sender's private key could not get any secret information between these participates before this communication.By these methods the improved schemes achieve public verifiability and forward security simultaneity.
