Cyber Security requires cryptology for the basic protection. Among different ECRYPT technologies, stream cipher plays a central role in advanced network security applications; in addition, pseudo-random number generators are placed in the core position of the mechanism. In this paper, a novel method of pseudo-random number generation is proposed to take advantage of the large functional space described using variant logic, a new framework for binary logic. Using permutation and complementary operations on classical truth table to form relevant variant table, numbers can be selected from table entries having pseudo-random properties. A simple generation mechanism is described and shown and pseudo-random sequences are analyzed for their cycle property and complexity. Applying this novel method, it can play a useful role in future applications for higher performance of cyber security environments.
