Abstract

In order to effectively against differential power attacks(DPA), masking schemes are usually used to protect the cryptographic primitives at the algorithm level. The existing threshold implementations mainly relies on the manual decomposition, calculation of the core components of the cryptography and the configuration of fresh randomness. Its obvious disadvantage regarding to both the calculation and verification process is quite complicated and cumbersome. In particular, the realization efficiency of these masking schemes is rather low. How to automatically generate a mask scheme without any fresh randomness appears to be a hot issue currently discussed in the industry. This paper proposed a new automatic threshold implementation, which was based on the minimum shared number of dependent functions. More precisely, random numbers of this scheme were only inserted in the variable decomposition phase. The experimental results illustrate that the peak value of T-test is reduced by more than 10 times(compared with the original peak value without protection), where the method is applied to the lightweight encryption algorithm LBlock, and 16 different optimal 4 bit S-boxes. On the other hand, in the practical DPA scenario and simulation platform, any users secret key bits of LBlock encryption algorithm cannot be captured even using 1 million power traces. This directly means that the mask protection scheme is rather effective. Similarly, this paper also presented an automation technique to design the first-order masked implementation schemes without any fresh randomness for the S-boxes used in SKINNY, Midori, PRESENT, and PRINCE encryption ciphers.
