Trusted computing is a promising technology for enhancing the security of platform by the TPM. The TPM is a tamper-resistant microcontroller designed to provide robust security capabilities for the trusted platform. It typically is affixed to the motherboard with LPC bus. However, It is so limitary that TPM can't be directly used in currently common PC, TPM isn't flexible and portable to be used in...
SMS4 is the first national standard of cryptographic algorithm in China. It is a block cipher with 128 bits key. Because SMS4 is a relatively new algorithm, there are no hardware accelerators specific to it on smartcards and it is not a standard algorithm in Java Card specification until now. In this paper, SMS4 was designed and implemented on Java Card. At first, we designed the architecture and...
USB key represents one of the smallest computing platforms today. With the development of USB key chips, more and more security features will be supported by USB key. Network security middleware is a Java and HTTP-based development framework on USB key. Developers can develop and on line load network security-related programs on this framework. End users can use this USB key to establish secure network...
SMS4 is the first national standard of cryptographic algorithm in China. It is a block cipher with 128 bits key. Because SMS4 is a relatively new algorithm, there are no hardware accelerators specific to it and no proposal to implement it on smart cards until now. In this paper, SMS4 was designed and implemented on smart cards. At first, the optimized implementation algorithm of SMS4 was given so...
