CCA-secure unidirectional proxy re-encryption in the adaptive corruption model without random oracles被引量：12
《Science China(Information Sciences)》2010年第3期593-606,共14页WENG Jian CHEN MinRong ANG YanJiang DENG Robert CHEN KeFei BAO Feng 
supported by the Office of Research, Singapore Management University;supported by the National Natural Science Foundation of China (Grant Nos. 60903178,90704004,60703030,60873229);the National High-Tech Research & Development Program of China (Grants Nos.2009AA01Z418,2008AA01Z403,2007AA01Z456)
Up to now, it is still an open question of how to construct a chosen-ciphertext secure unidirectional proxy re-encryption scheme in the adaptive corruption model. To address this problem, we propose a new unidirection...

通用可组合安全的门限签名协议被引量：9
《通信学报》2009年第6期1-6,共6页洪璇 陈克非 李强

门限签名协议使得签名团体中任何t个参与者合作可以生成某个消息的有效签名;而少于t个参与者就无法得到该消息的合法签名。目前关于门限签名协议的安全性研究只是专注于单一协议执行时的安全性,针对这点,引入通用可组合框架。利用该框...

On Constructing Certificateless Proxy Signature from Certificateless Signature
《Journal of Shanghai Jiaotong university(Science)》2008年第6期692-694,共3页万中美 来学嘉 翁健 洪璇 龙宇 贾巍巍 
the National Natural Science Foundation of China (Nos. 60573032, 60773092, 90604036,90704004)
In proxy signature schemes, an original signer A delegates its signing capability to a proxy signer B, in such a way that B can sign message on behalf of A.The recipient of the final message verifies at the same time ...
