Abstract :
We present a new method to provide secure communication in PCS. Our method is based on Data Encryption Standard (DES) encryption/decryption implemented on the mobile handset. It is shown that the proposed algorithm yields higher security compared to GSM authentication protocol at the expense of using more computational time at call setup, which is still negligible. However, in long run transmissions, the time taken to transmit data using our approach is less than that using GSM approach. Our approach is simple, easy to implement, and it can be very useful in present and future wireless communications
