Phil Zimmerman, the founder of the Pretty Good Privacy (PGP) program to keep e-mails safe, is now working on a new application to encrypt VoIP.
He says most internet-based phone calls are sent unscrambled, and this makes it possible for anyone to intercept the traffic and eavesdrop. His new project scrambles the data until it reaches the destination, making it impossible to intercept the VoIP phone calls.
“If you want to have an encrypted call, then you have to call someone running the same software at the other end,” Zimmermann said Wednesday. “Eventually, I'm hoping companies that make VoIP phones will incorporate this protocol into their phones.”
The program is slated for broad deployment within a year, but it isn't sure whether he will make it opensource. More details at InformationWeek
