Research on the Variation of the Computer Virus Based on Random Function

Studying the variation principle of the computer virus can deeply understand and grasp the variation laws and trends of the computer virus; offer the theoretical foundation for technical research of the anti-virus. In the foundation of summarizing the principle and the development of the virus technology, we introduced the idea of joining the random function in the trigger module of computer virus, in order to realize the computer virus variation similar to the biological virus and achieve a certain degree of the evolution. Then the method of realizing random function which utilizes Windows time function and logistic map is presented. This research provides theoretical basis for the anti-virus technique study, prevents virus from spreading effectively and ensures the security of online information.
