Father of PGP encryption: Telcos need to get out of bed with governments
Phil Zimmermann, the creator of Pretty Good Privacy public-key encryption, has some experience when it comes to the politics of crypto. During the "crypto wars" of the 1990s, Zimmermann fought to convince the US government to stop classifying PGP as a "munition" and shut down the Clipper Chip program—an effort to create a government-mandated encryption processor that would have given the NSA a back door into all encrypted electronic communication.
