Phil Zimmermann, creator of the PGP email encryption system, will soon publicly release the VoIP encryption software he first announced last July at the Black Hat security conference in Las Vegas. (See Encrypting Voice: An Interview with Phil Zimmermann, Creator of PGP.)
The software, dubbed zFone, differs from the encryption system used by Skype, for example, because it doesn’t involve a centrally managed system for handling encryption keys.
