Anti-clone function
The SRIX4K provides an anti-clone function that allows the application to authentication the
device. This function uses reserved data that is stored in the SRIX4K memory at its time of
manufacture.
The Authentication system is based on a proprietary challenge/response mechanism which
allows the application software to authenticate any member of the secure memory tag
SRXxxx family from STMicroelectronics (of which the SRIX4K is the prime example). A
reader system, based on the ST CRX14 chip coupler, can check each SRIX4K tag for
authenticity, and protect the application system against silicon copies or emulators.
A complete description of the Authentication system is available under Non Disclosure
Agreement (NDA) with STMicroelectronics. For more details about this SRIX4K function,
please contact your nearest STMicroelectronics sales office.
