| Research Abstract |
In this study, a systematic method for protecting software against malicious reverse engineering attacks is proposed. The method transforms an arbitrary part of the program into a time-sensitive code, that is, a code which is modified during execution according to the time taken to execute a part of the program. The method helps to efficiently increase the cost of obtaining secret information via dynamic attacks. The achievements include the development of the algorithm, the implementation of the prototype system, and the evaluation of the effectiveness of the proposed method.
