Protection against Reverse-Engineering, Counterfeiting/Cloning and Overbuilding
Problem: Revenue Protection
Unprotected firmware IP can be reverse engineered and exploited in multiple ways. Companies are looking for solutions to keep their IP and design secrets safe, and protect against counterfeiting/cloning and overbuilding.
Solution: Protection Based on SRAM PUF
Anti-Reverse-Engineering
Firmware IP is encrypted with an SRAM PUF-derived encryption key that is locked to the hardware instance of the device.
Anti-Cloning
When the firmware IP tied to a device by SRAM PUF is copied to other device instances, these rogue devices cannot unlock the IP and use it, since they have different hardware fingerprints.
Anti-Overbuilding
The number of SRAM PUF enrollments in devices can be limited to protect against overbuilding.
