Page "Phil Zimmermann" Paragraph 4

After the government dropped its case without indictment in early 1996, Zimmermann founded PGP Inc. and released an updated version of PGP and some additional related products.

That company was acquired by Network Associates ( NAI ) in December 1997, and Zimmermann stayed on for three years as a Senior Fellow.

NAI decided to drop the product line and in 2002, PGP was acquired from NAI by a new company called PGP Corporation.

Zimmermann served as a special advisor and consultant to that firm until Symantec acquired PGP Corporation in 2010.

Zimmermann is also a fellow at the Stanford Law School's Center for Internet and Society.

He was a principal designer of the cryptographic key agreement protocol ( the " association model ") for the Wireless USB standard.
