At Eurocrypt'06, Lu et al. presented the first Sequential aggregate signature(SAS) provably secure without random oracles. The drawback of their scheme is that users need long public keys and the security model makes ...

Secure and Efficient Proxy Signature Scheme in the Standard Model被引量：1
《Chinese Journal of Electronics》2013年第4期666-670,共5页GU Ke JIA Weijia CHEN Rongyuan LIU Xingbao 
Existing proxy signature schemes are not proved to have complete security in the provable security model for proxy signature＇s whether the schemes are secure needs to be further studied. We show a generalized prov- a...

An Efficient Signature Scheme with Tight Reduction被引量：1
《Chinese Journal of Electronics》2007年第2期202-205,共4页XU Jing FENG Dengguo 
This work is supported by the National Natural Science Foundation of China （No.90604018, No.60673083, No.90604010） and by the President＇s Foundation of Graduate School of CAS （No.055001H）.
Much recent work has focused on constructing efficient digital signature schemes whose security is tightly related to the hardness of some underlying cryptographic assumptions. With this motivation in mind, we propose...

A Short Provably Secure Proxy Signature Scheme
《Chinese Journal of Electronics》2006年第4期721-724,共4页LI Jin WANG Yanming 
The paradigm of proxy signature is a method for an entity to delegate signing capabilities to other participants so that they can sign on behalf of the entity. Proxy signature is one of important cryptographic protoco...
