A PUBLIC VERIFIABLE CERTIFICATELESS HYBRID SIGNCRYPTION SCHEME
摘要
Abstract
Certificate-based signcryption and identity-based signcryption are poor resistance to dishonest KGC,and the public key-based signcryption limits the length of the plaintext.The certificateless mechanism can reduce rely on KGC,while hybrid encryption can encrypt any length of plaintext.Combining the certificateless mechanism and the hybrid encryption mechanism,this paper presents a certificateless hybrid signcryption scheme based on bilinear pairings.On the basis of BDH problem and CDH problem,it is proved that the scheme has the confidentiality and adaptability of adaptive chosen ciphertext attack in random oracle model,as well as the unforgeability of chosen plaintext attack,and the scheme is publicly verifiable.Through efficiency analysis,the proposed scheme is efficient and suitable for applications where the bandwidth is limited.关键词
