CDMA is one of multiple access system, which applied at peripatetic communications system, to serve some Mobile Station (MS) by a Base Transceiver Station (BTS) applies air media (radio/wireless). Purpose of which wish to be reached is to study encryption-decryption process at network CDMA, with simulation approach applies program matlab. With program planning to process encryption of decryption for voice channel by using input which have been in the form of bit, using reverse traffic channel frame by 4800 bps, Shared Secret Data ( SSD) input, External of Encryption. Simulation program can work properly for getting the result of voice encryption as a bit become encode ciphertext.
