Title: Identity-Based Hybrid Signcryption Scheme Using ECC
Abstract: Identity-Based hybrid signcryption can efficiently encapsulate symmetric key and securely transmit data.Aiming at high computational complexity problem that exists in the existing identity-based hybrid signcryption schemes,this article integrates identity-based hybrid signcryption and bilinear maps in elliptic curve cryptography(ECC),and constructs a novel identity-based hybrid signcryption(IBHS) scheme using ECC.In the random oracle model,the paper proves that the constructed scheme satisfies the confidentiality under the co-bilinear Diffie-Hellman assumption and unforgeability under the co-computational Diffie-Hellman assumption.Since this scheme has low communication cost and high computational efficiency,it can be more practical in cryptography.
