The Verifier core is a robust, anti-counterfeiting hardware core designed to provide authentication with the highest level of tamper resistance.
The core can be used in conjunction with the CryptoFirewall Consumable core as part of a complete consumable protection system. It integrates into the device SoC and communicates to the CryptoFirewall Consumable core to authenticate and verify system integrity of the consumable or peripheral.
The Verifier core monitors the balances of the usage counters within the Consumable core, denying authentication once the balance reaches zero.
The design of chip anti-tamper protection needs to adapt and scale with rising threats. Adversaries range from high school hackers to well-funded state actors. Given the threats, it’s useful to think about anti-tamper countermeasures as a hierarchy of safeguards that parallel the type, effort and expense of attacks. Watch this webinar to learn the eleven kinds of tampering attacks and their required skills and resources, and countermeasures for each of these attacks.
Using field-proven, integrated anti-tamper security technologies, the Consumable core works in conjunction with either the CryptoFirewall Verifier core or Verifier firmware to provide consumers and manufacturers assurance of authenticity.
Secure device authentication: Each consumable or peripheral contains a low-cost security chip with the Consumable core that communicates with either a CryptoFirewall Verifier core or with Verifier firmware on the system-side SoC to authenticate and verify system integrity.
Secure usage authentication: The core contains usage counters with balances to authorize and track usage. Balances can be securely decremented with each use, and counters cannot be reset without a strict authentication process.
Part of a complete solution to protect against a broad range of attacks including:
Secure device authentication
Secure usage authentication
Gate-level netlist targeted to vendor-specified cell library
