ULTRA-WIDEBAND (UWB) is a new technology that provides high data rate and low power consumption. The physical layer built in of DS/CDMA UWB is provided by short pulses of nanosecond, the low output power and the absence of carrier signal. CDMA methods are considered as the main proposed method in this paper by integrating cryptographic techniques into the transceiver design. The two main methods that used in enhancement physical layer of CDMA are proposed to be used in DS/CDMA UWB in this paper. The first one is hidden direct sequence for encrypting spreading code. The second one is secure scrambling method at chip rate, which is based on Advanced Encryption Standard (AES) and Output Feedback Mode (OFB). The hybrid method is found much stronger than using anyone of the above method individually.
