Cell Phone Encryption?

Posted by Cliff on from the keeping-prying-ears-out-of-your-conversations dept.

Black Diamond asks: "I know I'm not up to speed on cell phone encryption, but I was wondering, are there any cell phones that let you handle the encryption from your end of things? Something along the lines of a phone you hook up to your computer to input specific encryption keys for specific contacts, as well as a private key for yourself. Is such a thing plausible, or should you trust the standard encryption that comes on some cell phones nowadays?"

  1. It is possible, and it is real by kousik · · Score: 5, Informative

    But not in the form you say. There exist chips which will do a Diffie-Hellman exchange to set up a secret key, and then do AES encryption on the whole conversation. Comes as a Sony-Ericsson accessory.

    Of course, lack of standard make these chips non-interoperable (not encryption/decryption but key management). Once it becomes popular standards need to emerge.
