The chip includes a hardware processing circuit to sequentially perform a processing related to the secret. The secret is retrieved from the memory device and processed in the hardware processing circuit in accordance with information included in the received challenge. The result of the processing in the hardware processing circuit is transmitted as a response to the challenge. The hardware processing circuit executes in a parallel manner, thereby reducing a signal that can be detected by an adversary attempting a side channel attack to secure the secret."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Cryptographic side channel resistance using permutation networks","description":"A method (and structure) includes receiving a challenge for an authentication, in a chip having stored in a memory device therein a secret to be used in an authentication attempt of the chip by an ext","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11496285","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
