VaultIC150 is an NFC-based security IC which is designed for embedding into consumer or luxury products. The VaultIC150 is pushed by Inside Secure SA which is a fabless supplier of near field communication (NFC) chips. Inside provides luxury brand watches, handbags, wine and other consumables. And manufacturers can track their products through distribution and retail channels and allow customers with NFC-enabled mobile phones to verify products as original.

The VaultIC150 requires no battery since the NFC interface and embedded antenna collect the RF energy emitted by the reader device to power the security circuitry and communications interface. The security engine utilizes elliptic-curve mutual authentication. The security engine is designed to meet the EAL4plus and FIPS 140-2 L3 certification standards.

According to the operation in the simplest case, the NFC-enabled cell phone sends a random challenge message to the product to check if it is a genuine device. The device contains the embedded VaultIC150,. The VaultIC150 uses its securely-stored private key to compute the elliptic-curve digital signature of the challenge message and send it back to the phone or NFC reader. Using the corresponding public key, the host performs the necessary signature verification. For even greater security, the VaultIC150 can be employed as part of a public-key infrastructure (PKI).

However, the VaultIC150 provides these manufacturers with a simple, single-chip solution that provides banking-level security to protect their brands at an attractive price point.
