Anti-Tamper Active Shield

Solutions

onsemi's anti-tamper active shield architecture addresses information security, IP protection, and anti-counterfeiting in ASIC design by providing resistance, detection, and evidence against tampering. ASIC tampering involves altering a product's operation or uncovering proprietary information, targeting critical data. Counterfeiting activities like reverse engineering, IP theft, and repurposing returned merchandise pose daily threats to suppliers and customers. The active shield uses a random plane-filled curve with top-level metal over sensitive areas, functioning as a powered screen rather than just a blockage. While initially linked to aerospace and defense, the rise in personal electronics drives all market segments to adopt anti-tampering methods.
