Examples of the attack include micro-probing, fault injection, and electromagnetic wave analysis.A semiconductor device, in which a plurality of IC chips that perform the same cipher calculation in parallel are laminated or stacked, performs data processing including the cipher calculation. A chip that compares and verifies results of the cipher calculations performed by the plurality of chips is laminated in an intermediate layer whose element surface is covered by another chip. For example, when three chips are laminated, a chip in the intermediate layer sandwiched by the upper layer and the lower layer has a comparative verification function."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device","description":"In data processing including high-speed cipher calculation for which it is not appropriate to employ a leveling technique, tamper resistance is improved against an attack to a specific position perfor","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9667410","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.
