Device DNA Security

 

Protect Your Brand with Extended Spartan®-3A FPGAs

Companies lose over $500B in lost sales every year because of counterfeit products. This threat grows by more than 12% per year, tarnishing the reputation and long-term credibility of genuine brands.

Extended Spartan-3A devices enable designers to implement a low cost, highly robust security solution to deter reverse-engineering, cloning and overbuilding.

Our Device DNA demo highlights how easily Device DNA technology can be used to implement a low-cost security solution for high volume applications. It requires either the Spartan-3A FPGA Starter Kit or the Spartan-3AN FPGA Starter Kit. Documentation is provided.

How Device DNA Works

The Device DNA security mechanism is similar to an ATM transaction.

In an ATM transaction, the active value generated from the card + pin combination is compared to a number stored in a bank computer that authorizes or rejects the transaction.

Similarly, the unique 57-bit Device DNA number is used with a customer-defined security algorithm to generate an active value. The active value is compared to a pre-stored check value to determine whether design functionality can proceed.
