摘要：Security is of fundamental importance in digital communication. The system should be secure against brute force attacks and impersonation by the eavesdropper. Code and the sensitive data should only be accessed and understood by legitimate user/authority. Software in recent scenario has been highly susceptible to various attacks and threats. Reverse engineering is one of the key technique by which an intruder can understand the inner working of the software. Most of the existing software protection techniques do not provide reliable security against various attacks. Cryptographic approaches are observed to be very efficient in providing security and authentication to the software. Encryption of the code in the software has received much attention in the software engineering domain and various researches are being done in that area. This paper proposes a novel hybrid software protection code encryption scheme based on the index table. This approach uses a novel and efficient encryption technique for encryption the indexed table. The encryption technique used is the quasigroup approach which provides least resemblance of the original data when encrypted. The performance of the proposed approach is evaluated based on the time cost and space cost and it is observed that the proposed approach provides significant results and performance.
