Improving smart card security using self-timed circuits
Simon W. Moore, Ross Anderson, P. Cunningham, Robert Mullins, George S. Taylor · 2004
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.
