An updating of the value of this reference indication is performed on each write in at least one memory position by using the operator, the reverse operator and the values of the stored information before and after each write in the at least one memory position. And, in the presence of a request, a check is performed as to whether a criterion involving the values of the information stored in the memory positions at the time of the request and the operator or its reverse is or is not satisfied by the value of the reference indication at the time of the request."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for detecting an attack by fault injection into a memory device, and corresponding detection system","description":"The method for detecting an attack by fault injection into memory positions includes a generation of an initial value of a reference indication including an application of a reversible mathematical op","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8484731","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.
