Abstract:

We investigated the problem of the high-consumption implementation of S-box resisting Differential Power Analysis (DPA) Attacks and the more of these are on the small type. Then constructed a low-consumption S-box by the classical SPN framework and we obtained a new S-box based on the idea of secret sharing and optimized it according to the experimental data. With two small 4 bit S-box,we constructed a 8 bit S-box during carefully combination,for which the consumption of secret sharing was decreased. Simultaneously,we have decreased the small S-box and registers by multiplexing it for the feature of block cipher, and have further improved the effectiveness. Through the specific implementation chart and data processing results, we have given the ideal experimental parameters.

Key words: S-box, secret sharing, DPA attack, SPN framework, register multiplexing
