onsemi offers an anti-tamper active shield architecture as one of the first steps to tackle information security, IP protection, and anti-counterfeiting in ASIC design. ASIC tampering is a calculated attempt to alter the operation of a product or uncover proprietary information in the design or operation of an ASIC. Critical data of any kind can be a target. Counterfeiting activities like reverse engineering, stealing or copying intellectual property, and repurposing returned merchandise threaten suppliers and customers daily.

onsemi’s anti-tamper active shield satisfies three components of anti-tampering protection: resistance, detection, and evidence. onsemi’s anti-tamper active shield is a random plane-filled curve with built-in top-level metal over specific IP or sensitive areas of the ASIC. Multiple lines can be employed, and each function as a powered and active screen rather than blockage simply used to hide sensitive areas.

While the need for anti-tamper strategies is associated with aerospace and defense applications, the exponential rise of personal electronics usage drives all market segments to explore anti-tampering methods and offerings.
