Lightweight and Low-Energy Encryption Scheme for Voice over Wireless Devices

Abstract

In this work, a novel lightweight and low energy encryption algorithm for voice over wireless networks is being developed and tested. The new encryption algorithm has to meet the QoS requirements of voice traffic and to be suitable for wireless devices. The goal of the research was to reduce the execution time and power consumption of the encryption process compared with the standard algorithm and at the same time at least to maintain or to increase its security level. The proposed algorithm employs similar methods with those used in the Advanced Encryption Standard algorithm (AES), with some changes and enhancements considering the limitations of wireless devices. The test results show significant improvements in new design metrics. A range of simulation scenarios are setup; testing data is analyzed to test delay, energy and security. Also, the comparison between the new algorithm and the standard one shows a significant amount of time and energy consumption reduction being achieved (approximately 35%), with good-level of complexity, making it more suitable for the wireless environment.

Security Scheme Enhancement for Voice over Wireless Networks

“…Some of them focus on developing algorithms that suit dealing with real time limitations such as delays while some others focus on the complexity of the security algorithm and neglect the performance (encryption delay, Energy) requirements. This work expands our previous work [20] which developed a new lightweight encryption scheme. The main contribution of this paper is to conduct further security analyses which are missing in previous works and to test brute force attack on the newly proposed algorithm.…”

“…Reported results in [16] have shown that the enhanced KP-ABE model remarkably offers low running time as compared to other similar encryption algorithms. In [17], an enhanced version of the AES encryption algorithm in terms of running time and energy consumption has been presented. Obtained results in [17] have confirmed it is fair to claim that enhanced algorithm is lightweight and efficient for voice applications in wireless systems.…”
