Zero-pole cancellation for identity-based aggregators:a constant-size designated verifier-set signature
《Frontiers of Computer Science》2020年第4期197-210,共14页E CHEN Yan ZHU Changlu LIN Kewei LV 
The work was supported by the National Key Technologies R&D Programs of China(2018YFB1402702 and 2017YFB0802500);the“13th”Five-Year National Cryptographic Development Foundation(MMJJ20180208);NSFC-Genertec Joint Fund For Basic Research(U1636104);the National Natural Science Foundation of China(Grant Nos.61572132,61972032 and U1705264).
In this paper we present a designated verifier-set signature(DVSS),in which the signer allows to designate many verifiers rather than one verifier,and each designated verifier can verify the validity of signature by h...

On-line/Off-line Threshold Proxy Re-Signatures被引量：5
《Chinese Journal of Electronics》2014年第2期248-253,共6页YANG Xiaodong WANG Caifen ZHANG Lei QIU Jianbin 
supported in part by the National Natural Science Foundation of China(No.61262057,No.61063041,No.61163038);the Young Teachers’Scientific Research Ability Promotion Program of Northwest Normal University(No.NWNU-LKQN-10-22)
To improve the performance of threshold proxy re-signatures, the notion of on-line/off-line threshold proxy re-signatures is introduced. The bulk of re-signature computation can be done in the off-line phase before th...

Forgeability of Wang-Zhu-Feng-Yau’s Attribute-Based Signature with Policy-and-Endorsement Mechanism
《Journal of Computer Science & Technology》2013年第4期743-748,共6页葛爱军 黄欣沂 陈成 马传贵 张锐 
partially supported by the National High Technology Research and Development 863 Program of China underGrant No.2011AA010803;the National Natural Science Foundation of China under Grant Nos.61100225, 61202450;the funding of Science and Technology on Information Assurance Laboratory (KJ-13-02);the Key Scientific and Technological Project of Henan Province of China under Grant No. 122102210126
Recently, Wang et al. presented a new construction of attribute-based signature with policy-and-endorsement mechanism. The existential unforgeability of their scheme was claimed to be based on the strong Diffie-Hellma...

Attribute-Based Signature with Policy-and-Endorsement Mechanism被引量：1
《Journal of Computer Science & Technology》2010年第6期1293-1304,共12页王怀习 朱岩 冯荣权 Stephen S.Yau 
supported by the National Nature Science Foundation of China under Grant No.10990011;the National Science Foundation of US under Grant No.CCF-0725340;the National Development and Reform Commission under the project of "A Monitoring Platform for Web Safe Browsing";China Next Generation Internet CNGI Project under Grant No.CNGI-09-01-12
In this paper a new signature scheme,called Policy-Endorsing Attribute-Based Signature,is developed to correspond with the existing Ciphertext-Policy Attribute-Based Encryption.This signature provides a policy-and-end...

Generic Transformation from Weakly to Strongly Unforgeable Signatures被引量：1
《Journal of Computer Science & Technology》2008年第2期240-252,共13页黄琼 王石 李进 赵一鸣 
The first two authors are supported by a grant from City University of Hong Kong(Grant No.7001844);The third author is supported by 2nd stage of Brain Korea 21 Project sponsored by the Ministry of Education and Human Resources Development, Korea;The fourth author is supported by National Natural Science Foundation of China(Grant No.60573054).
Current techniques for transforming unforgeable signature schemes （the forged message has never been signed） to strongly unforgeable ones （the forged message could have been signed） require supplementary component...
