| Outline of Final Research Achievements |
Research and development on computational intelligence techniques based on advanced sequence analysis are pursued in the aim of an analysis system that can detect polymorphic malware programs with good accuracy and efficiency. The newly proposed edit distance kernel function and spectrum kernel function make it possible to quantitatively evaluate the degree of similarity between sequences. Incorporating these kernel functions to the state-of-the-art classifiers, such as the support vector machine, renders the creation of a practical malware detection system possible. The proposed methods are evaluated using a database comprised of obfuscated programs generated by 25 types of packers. Their effectiveness and efficiency are illustrated by prediction accuracies over 99% and very quick system response time.
