NXP – Security IC offers turnkey solution to product authentication


The A1006 from NXP Semiconductors is a secure, tamper-resistant authentication IC which offers a strong cryptographic solution intended to be used by device manufacturers to prove the authenticity of their products.

The A1006 is offered as a turnkey solution which provides designers with an easy means to integrate authentication functions into their end-products. Because it offers high-speed operation and low power consumption, it has a minimal impact on the performance of the end-product design. The time to perform authentication operations on-chip is less than 50ms. Operating current in active mode is just 500μA.

The A1006’s security is based on a unique asymmetrical public/private key Diffie-Hellman authentication protocol. There are two different keys for encryption and decryption based on Elliptic Curve Cryptography (ECC), with a NIST B-163 binary field curve.

In addition, each A1006 has a static pair of ECC private keys and corresponding certificate which contains the public key and additional information, including a unique identifier and the customer’s product fields and usage data.

The A1006’s certificates are digitally signed using an Elliptic Curve Digital Signature Algorithm (ECDSA) based on the NIST P-224 curve and the SHA-224 digest hash. Non-volatile memory is available for storage of data about device behaviour and logistics as well as arbitrary data.
