Improved Certificateless Signcryption Scheme without Pairing

Abstract: A certificateless signcryption scheme without pairing was analyzed.This paper showed the scheme can not achieve confidentiality and unforgeability.The mistakes in the security proofs were pointed out,and an improved scheme was proposed.The improved scheme was proved to be confidential under the computational diffie-hellman(CDH) assumption and existentially unforgeable under the discrete logarithm(DL) assumption in random oracle model(ROM).Performance analysis shows the improved scheme is of high efficiency.

Key words: Certificateless signcryption,Confidentiality,Unforgeability,Bilinear pairings,Random oracle model
