An Efficient Heterogeneous Signcryption Scheme from Certificateless to Identity-based Cryptosystem

摘要：

　　The heterogeneous signcryption can not only realize the confidentiality and un-forgeability of the information transmission between different public key cryptography environments,but also reduce the communication cost.The proposed scheme uses bilin-ear pairings between certificateless cryptography and identity-based cryptography to construct a heterogeneous signcryption scheme.In addition,two cryptography systems use different secret master keys.Furthermore,the proposed scheme has the indistin-guishability against adaptive chosen ciphertext attacks and existential unforgeability against adaptive chosen-message attacks in the random oracle model.Through the data analysis,this scheme is more effective than other similar types of scheme.
