Method Of Protecting Secret Data When Used In A Cryptographic Algorithm
Abstract: The present disclosure concerns a method of generating a protected implementation of an algorithm the method comprising: expanding an original source code implementing the algorithm into a single set of real operations; combining each real operation using real data with the real data it uses to obtain a combination represented in a way which uses an actual real data fragment in a form different from an original form; producing a set of duplicated and mutated decoy operations representing an alternative implementation of the algorithm applied to decoy data; combining the set of decoy operations with the set of real operations including the combinations to obtain an implementation where the decoy operations interact with the real operations and the real data processed by the real operations such that a real data flow of in the implementation is difficult to analyze; and transforming the implementation into a resulting code that can be executed.
