Chosen Ciphertext Secure Identity-Based Broadcast Encryption in the Standard Model被引量：1
《Journal of Shanghai Jiaotong university(Science)》2011年第6期672-676,共5页孙瑾 胡予濮 张乐友 
the National Natural Science Foundation of China (No.60970119);the National Basic Research Program (973) of China (No.2007CB311201)
To give concurrent consideration both the efficiency and the security(intensity of intractable problem) in the standard model,a chosen ciphertext secure identity-based broadcast encryption is proposed.Against the chos...

An Identity-Based Encryption Scheme with Compact Ciphertexts
《Journal of Shanghai Jiaotong university(Science)》2009年第1期86-89,共4页刘胜利 郭宝安 张庆胜 
the National Natural Science Foundation of China(Nos.60673077,60873229)
This paper proposes an identity-based encryption scheme with the help of bilinear pairings, where the identity information of a user functions as the user＇s public key. The advantage of an identity-based public key s...

The Gap between Intractable Problem and Adaptive Chosen Ciphertext Security
《Journal of Shanghai Jiaotong university(Science)》2009年第1期90-93,共4页路献辉 来学嘉 何大可 
the National Natural Science Foundation of China(Nos.60573032,60773092,90604036)
To describe the design approaches of IND-CCA2 （adaptive chosen ciphertext attack） secure public key encryption schemes systematically, the gaps between different kinds of intractable problems and IND-CCA2 security a...

Chosen Ciphertext Secure Fuzzy Identity Based Encryption without ROM
《Journal of Shanghai Jiaotong university(Science)》2008年第6期646-650,共5页方黎明 王建东 任勇军 夏金月 卞仕柱 
the National High Technology Research and Development Program (863) of China(No. 2006AA12A106)
Two new constructions of chosen-ciphertext secure fuzzy identity-based encryption （fuzzy-IBE） schemes without random oracle are proposed. The first scheme combines the modification of chosen-plaintext secure Sahai a...
