Abstract: The wireless transmission of different type of data like images, texts, videos etc. through an open network is considered as prone with respect to several security threats and passive attacks. CDMA communication systems used for various wireless communications requires improved cryptographic algorithms and air interface security checks. The -ary cryptographic function with suitable properties are key elements in providing secure transmission of data through wireless network. In this paper, we use the Walsh-Hadamard spectrum as a fundamental tool for analysis of some properties of generalized -ary functions. We generalize some existing results obtained for Boolean functions to the -ary functions and obtain some new characterization of -ary functions based on spectral analysis.
