Abstract
A security module for use in a cellular telephone provides for low power consumption. The security module includes a vocoder processor for manipulating signals from the telephone's microphone and to the telephone's ear piece; an encryption engine; a modem processor for controlling transmitted and received data from the cellular telephone; and a security system controller. The processors consume virtually no power when the phone is in the standby mode and very little power to produce encrypted communication when the cellular phone is operational.
