Even though that CDMA 2000 wireless networks is being widely deployed as a cellular digital standard around the world, it has some hidden vulnerabilities when concerned with the security issues. The main focus of this paper is to propose MANAGE1 as a design of a new stream cipher system to be used for data encryption in CDMA wireless networks. This new cipher system is intended to replace the offered data encryption algorithm in CDMA networks known as ORYX. The proposed cipher system is being assessed from different aspects. The first aspect addresses the period and linear complexity profiles of the generated keystream. The second is the statistical properties of the keystream, which are being tested using the standard statistical tests. It is shown that MANAGE1 cipher system improves the practical security over the ORYX, thus ensuring that data security in CDMA networks becomes more reliable to suit the high demand of secure data transmissions in the next generation of wireless communications.
