Mechanism for secure transmission of signals in wireless communication devices
First Claim
1. A method of securely transmitting signals by a primary wireless communication device comprising:
- receiving a value from a wireless carrier;
transmitting said value to a secondary wireless communication device;
receiving a first output from said secondary wireless communication device, said first output generated using a first algorithm, said value and a key;
applying a second algorithm using said first output to generate encrypted signals; and
transmitting said encrypted signals to said wireless carrier.

Abstract
One or more systems and methods are disclosed to provide secure transmission of signals by a primary wireless communication device that utilizes a secure multi-tier signal encryption mechanism. A secondary signal encryption mechanism of a secondary wireless communication device generates an intermediary algorithmic output required in the encryption processing at a primary signal encryption mechanism of a primary wireless communication device. In one embodiment, the secondary signal encryption mechanism comprises a subscriber identity module (SIM) card. In one embodiment, wireless signal transmission occurs over a GSM/GPRS/EDGE network.
