Threshold implementation is a method based on secret sharing to secure cryptographic ciphers (and in particular S-boxes) against differential power analysis. Until now, threshold implementations were only constructed for specific types of functions and some small S-boxes, but no general construction for all S-boxes was ever presented. The lower bound for …
