TEAleaf is a low cost authentication system which may be
used to verify that a product is genuine and paid-for. The host processor uses a
simple but extremely robust algorithm to verify that a TEAleaf device is present.
Each TEAleaf carries a 128-bit encryption key and an individual serial number.
TEAleaf ensures copies of your products cannot be manufacturerd
by unlicensed third parties. It
eliminates the need for trust and auditing when subcontracting manufacture, licensing
to OEMs or publishingfirmware libraries. Applications include:
• Product authentication (printer ink
cartridges, camera lenses, etc)
• Firmware library protection
• Electronics product design licensing
