  • Tamper Resistance for Software Defined Radio Software
    2009 33rd Annual IEEE International Computer Software and Applications Conference, 2009
    Co-Authors: Shucai Xiao, Jung-min "jerry" Park, Yanzhu Ye
    Abstract:

    The security of software defined radio (SDR) software is essential to the trustworthiness of the overall radio system. When designing and developing security solutions for SDR software, its performance requirements, such as stringent real-time constraint, need to be considered. In this paper, we describe a tamper resistance scheme that was designed to thwart the unauthorized tampering of SDR software. This scheme utilizes Code Encryption and branch functions to obfuscate the target program while enabling the program to satisfy its performance requirements. The scheme employs a technique called the Random Branch Function Call (RBFC), which enables a user to control the tradeoff between integrity checking frequency and the overhead. We have rigorously evaluated the scheme using various performance metrics and quantified the relationship between the end-to-end delay overhead (caused by the tamper resistance scheme) and voice quality in the context of a voice communication network.

  • Novel Secure Code Encryption Techniques Using Crypto Based Indexed Table for Highly Secured Software
    International Review on Computers and Software, 2013
    Co-Authors: N Sasirekha, M Hemalatha
    Abstract:

    Software security has become one of the active areas of research due to various cyber threats and attacks that can be very dangerous. The main goals of software protection are Intellectual property protection, Protection beside function investigation in mobile environments, Protection beside illegal copy and use of software. Software security is dependent on both security Code and software protection. Various techniques have been developed to deal with the software threats and attacks. However, the available software protection approaches in the literature do not offer trustworthy security in all the scenarios. In recent years, cryptographic techniques are observed to be very efficient in dealing with a number of software threats and attacks. Code Encryption has received much attention in the field of software security. This paper proposes novel software protection Code Encryption schemes based on the index table. This approach uses three novel and efficient Encryption techniques namely quasigroup Encryption, quasi group Encryption with transformation and KIST approach

  • CCSEIT - An efficient secure Code approach based on indexed table quasi group Encryption with Hadamard and Number Theoretic Transformation for software protection
    Proceedings of the Second International Conference on Computational Science Engineering and Information Technology - CCSEIT '12, 2012
    Co-Authors: N Sasirekha, M Hemalatha
    Abstract:

    Software security has become one of the active areas of research due to various cyber threats and attacks that can be very dangerous. A majority of these software threats directly affects the security aspects such as confidentiality, integrity and accessibility. These software threats such as reverse engineering, tampering, etc., exploit the authenticated data of the software. Various techniques have been developed to deal with the software threats and attacks. But, most of the existing software protection techniques do not provide reliable security against various attacks. Recently, Cryptographic approaches are found to be very effective in handling the software threats and attacks. Code Encryption has received much attention in the field of software security. This paper proposes a novel software protection Code Encryption scheme based on the index table. This approach uses a novel and efficient Encryption technique called quasigroup Encryption for Encryption the indexed table. It provides least resemblance of the original data when encrypted. Quasigroups effectively produce an astronomical number of keys which confuses the hackers in identifying the original data. But, quasi group Encryption is not efficient in diffusing the statistics of the plain text. Hence, this approach uses chained Hadamard transforms and Number Theoretic Transforms to introduce diffusion along with the quasigroup transformation. The experimental results evaluate the performance of the proposed Encryption approach based on the time cost and space cost and it is observed that the proposed approach provides significant results.

    International Journal of Computer Applications, 2012
    Co-Authors: N Sasirekha, M Hemalatha
    Abstract:

    threats such as viruses, worms, trojans and spyware affects the security and authentication of software Codes, forcing software developers to build security schemes for better software protection. These software threats exploit the authenticated data of the software and confidentiality, integrity and accessibility is greatly affected by these software threats. A number of Code security techniques like tamper resistant packaging, Code obfuscation, register encoding etc have been developed which mainly concentrates on providing solutions for a particular type of threats and are vulnerable to Code tampering and Code injection by complicated attackers. Hence, Code Encryption technique has become an active area of research. This paper proposes a novel software protection Code Encryption scheme based on the index table. This approach uses a novel and efficient Encryption technique called quasigroup Encryption for Encryption the indexed table. It provides least resemblance of the original data when encrypted. But, quasi group Encryption is not efficient in diffusing the statistics of the plain text. This drawback can be overcome by using transforms. Hence, this approach uses chained Hadamard transforms and Number Theoretic Transforms to introduce diffusion along with the quasigroup transformation. The proposed approach is compared with the other Encryption approaches and is observed to provide better results.
