CryptoFirewall Consumable Core

Our hardware-based Consumable core is a cost-effective and robust security solution designed to prevent counterfeiting of mass-market consumables and peripherals including mobile accessories, medical devices, printer supplies, batteries and automotive components. This tamper-resistant security core can be integrated into existing chips, or implemented as a discrete security chip on consumables for unsurpassed protection against counterfeiting.

Product Brief

CryptoFirewall Consumable Core block diagram

How it works

Using field-proven, integrated anti-tamper security technologies, the Consumable core works in conjunction with either our CryptoFirewall Verifier core or 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 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 are decremented with each use, and once the balance reaches zero, the system no longer authenticates.
