Improving Smart Card Security Using Self-Timed Circuits
نویسندگان
چکیده
We demonstrate how 1-of-n encoded speed-independent circuits provide a good framework for constructing smart card functions that are resistant to side channel attacks and fault injection. A novel alarm propagation technique is also introduced. These techniques have been used to produce a prototype smart card chip: a 16-bit secure processor with Montgomery modular exponentiator and smart card UART.

Improving the Password-Based Authentication against Smart Card Security Breach
Password-based authentications using smart cards are very necessary between login users and a remote server. Smart card security breach threatens the security of password-based authentication schemes with smart cards. A password-based authentication scheme with smart cards against smart card security breach was proposed by C.T. Li et al. recently. However, it is noted that Li et al.'s scheme ne...
متن کاملA nonce-based mutual authentication system with smart card
User authentication is an important security mechanism for recognizing legal remote users. We propose an available and secure authentication scheme for service provider to verify users without using verification table. It can resist most of the attacks by improving nonce-based mutual authentication mechanism, and ensure the security by dynamic session key. User may change his password freely. O...
متن کاملSecurity Evaluation of Asynchronous Circuits
Balanced asynchronous circuits have been touted as a superior replacement for conventional synchronous circuits. To assess these claims, we have designed, manufactured and tested an experimental asynchronous smart-card style device. In this paper we describe the tests performed and show that asynchronous circuits can provide better tamperresistance. However, we have also discovered weaknesses w...
متن کاملAn Investigation into the Security of Self-Timed Circuits
Self-timed logic may have advantages for security-sensitive applications. The absence of a clock, as a reliable timing reference, makes conventional power analysis attacks more difficult. However, the variability of the timing of self-timed circuits is a weakness that could be exploited by alternative attack techniques. This paper introduces a methodology for the differential power analysis of ...
متن کاملOn the Remote Authentication with Self - Protected Smart Cards 植基於具自保功能智慧卡之遠端認證機制
Smart card is a secure device for remote authentication. However, if cardholders lost their card, attackers always can successfully guess passwords and impersonate legal users to login. In 2004, Lee et al. proposed a remote authentication scheme with smart cards. In this paper, we first show that their scheme cannot withstand the guessing attack. If attackers obtain the card, they can successfu...
