For each set of substitution operations of the cryptographic process, a series of sets of substitution operations are performed. One set of the series is a real set of substitution operations corresponding to the set of substitution operations of the cryptographic process. One or more other sets are dummy sets of substitution operations, each dummy set being based on a different permutation of said substitution tables."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for performing substitution table operations","description":"The disclosure concerns implementing, by a cryptographic circuit, a set of substitution operations of a cryptographic process involving a plurality of substitution tables.
