Certificateless Encryption Scheme Secure in Standard Model被引量：2
《Tsinghua Science and Technology》2009年第4期452-459,共8页张国艳 王小云 
Supported by the National Key Basic Research and Development (973) Program of China (No. 2007CB807902);the National Natural Science Foundation of China (Nos. 90604036 and 60525201)
The scheme introduced by Hwang and Liu in 2008 is shown to be insecure against the key re- placement attack. A more practical attack model is introduced, and according to this model, an efficient cer- tificateless enc...

Dedicated Linear Attack on ARIA Version 1.0
《Tsinghua Science and Technology》2009年第2期212-217,共6页李申华 张海纳 王小云 
Supported by the National Key Basic Research and Development(973) Program of China(No.2007CB807902);the National NaturalScience Foundation of China(Nos.90604036 and 60525201)
ARIA is a new block cipher designed as the block cipher standard of South Korea. The current version is 1.0, which is an improvement of version 0.8 with the security using four kinds of S-boxes instead of two and an a...

Simplified Design for Concurrent Statistical Zero-Knowledge Arguments
《Tsinghua Science and Technology》2009年第2期255-263,共9页魏普文 张国艳 张立江 王小云 
Supported by the National Key Basic Research and Development(973) Program of China(No.2007CB807902);the National Natural Science Foundation of China(Nos.90604036 and 60525201)
This paper shows that the protocol presented by Goyal et al. can be further simplified for a one-way function, with the simplified protocol being more practical for the decisional Diffie-Hellman assumption. Goyal et a...
