摘要 基于Chandrasekar等人提出的代理重加密签密方案(CHANDRASEKAR S,AMBIKA K,RANGAN P C.Signcryption with proxy re-encryption.http://eprint.iacr.org/2008/276),提出了一个新的基于身份代理重签密方案。该方案利用一个半可信代理人将一个基于身份的签密透明地转换为了另一个基于身份的签密,实现了签密的完全可转换:即同时实现了签密中保密功能和验证功能的转换,且签密的验证不需要明文信息的直接参与。在随机预言机模型下,基于计算性Bilinear Diffie-Hellman问题,证明了方案是IND-CCA2安全的。经效率和功能分析,结果表明该方案解决了Chandrasekar方案中验证功能未能转换的问题和签密的验证需要明文参与的问题。 A new identity-based proxy re-signcryption scheme was put forward on the basis of the signcryption with proxy re-encryption proposed by Chandrasekar S（CHANDRASEKAR S,AMBIKA K,RANGAN P C.Signcryption with proxy re-encryption.http：//eprint.iacr.org/2008/276）.The new scheme achieves a transparent conversion from one identity-based signcryption to another identity-based signcryption by using a semi-trusted proxy.And it realizes the complete conversion of signcryption,that is,it concurrently achieves the conversion of both confidentiality and verification.In the same time,it realizes the full public verifiability of the signcryption without the direct participation of the plaintext.Based on the Computation Bilinear Diffie-Hellman（CBDH） problem,it is proved to be IND-CCA2 secure in the Random Oracle Model（ROM）.Through the analysis of its efficiency and function,the scheme resolves the problems of both failing to realize the conversion of the verification and the verifiability of signcryption needing the participation of plaintext in the scheme advanced by Chandrasekar S.
