6.2.5 What is the Current Status of Clipper?
Clipper has been accepted as FIPS 185 [NIS94a] by the federal government. Various forms of the Clipper chip were produced; however, it is no longer in production. The chip is still used in the AT&T TSD 3600 and in various Fortezza products (see Question 6.2.6), including PC Cards, encrypting modems, and PCI board Fortezza. All Capstone-based products have suppressed LEAF (see Question 7.13) escrow access function. There is now a CA (Certifying Authority) performing key recovery.
