Techniques for Privacy and Authentication in Personal Communication Systems

Dan Brown

One-line summary: Authentication and privacy techniques used in GSM and IS-95 are presented, and the generic public/private key technique used as a basis for comparison.

Overview/Main Points


PCS privacy and authentication is a serious issue that has not historically been satisfactorily addressed by vendors. GSM and IS-95 have barely acceptable strategies; the public/secret key method described is well known to be stronger.
