In secure communications, chaos has the characteristics of excellent encryption technology, it is appropriate for applications in information encryption. But what the limited accuracy of the computer and simple structure of the chaotic system are easily threatened, and chaotic structure limits its practical application. To solve the problem, a new kind of chaotic encryption algorithm — dual chaos...
RSA is the asymmetric cryptography system. The security of RSA public key cryptosystem is based on the assumption that factoring of a large modulus is difficult. In RSA if someone can factor modulus into a product of two prime numbers, then the private key is also detected and hence the security of the cryptosystem is broken. So it is quite important to research the selection of prime and derive private...
In recent years, with the rapid development of computer information technology, a lot of information has been speeded with the internet. The information leaks often cause huge losses, so more and more attentions were paid to the research of information security. Hardware encryption card based on chaotic encryption algorithm is compared with traditional software encryption method, it has a speed computing,...
