ETel: Security on VoIP

Security on VoIPPhilip Zimmermann

Using the PGP servers as has a nice relationship, trying to do for VoIP what he did for email with PGP.

Looking at the way encrypted phone calls work under consideration at the IETF, 10 years ago created PGP for VoIP

Aim is to create disposable keys for each call so they can’t be retroactively used to decrypt calls after the event

Public key infrastructures have failed in general, to the degree that many went out of business

He gets a phone call which he answers “Hi, I’m giving a lecture so I can’t talk”

He wants to avoid PKI as not really used anywhere, he now gets into SSH and it’s too complex crypto talk for me…..

He ends with a statement that a public beta should be out at the end of February
