Modified constructions of binary sequences using multiplicative inverse
《Applied Mathematics(A Journal of Chinese Universities)》2008年第4期490-500,共11页CHEN Zhi-xiong LIN Zhi-xing 
Supported by the Open Funds of Key Lab of Fujian Province University Network Security and Cryptology (07B005);the Funds of the Education Department of Fujian Province (JA07164);the Natural Science Foundation of Fujian Province of China (2007F3086)
Two new families of finite binary sequences are constructed using multiplicative inverse. The sequences are shown to have strong pseudorandom properties by using some estimates of certain exponential sums over finite ...

Pseudorandomness on the Round-Structure of Skipjack
《Chinese Journal of Electronics》2006年第3期378-383,共6页WU Wenling WEI Hongru 
This work (No.60373047, 90304007); the National Basic Research 973 Program Development 863 Program of China (No.2003AA144030). is supported by the National Natural Science Foundation of China of China (No.2004CB318004) and the National High-Technology
Skipjack is a simple cipher, and one interesting feature is the use of two different types of rounds. These are referred to as A and B-rounds. Earlier researchers have studied the security of Skipjack against some att...

Pseudorandomness of Camellia-Like Scheme被引量:6
《Journal of Computer Science & Technology》2006年第1期82-88,共7页吴文玲 
Supported partially by the National Natural Science Foundation of China under Grants No, 60373047 and No, 90304007; the National Basic Research 973 Program of China under Grant No. 2004CB318004; the National High-Technology Development 863 Program of China under Grant No. 2003AA144030.
Luby and Rackoff idealized DES by replacing each round function with one large random function. In this paper, the author idealizes Camellia by replacing each S-box with one small random function, which is named Camel...
