| Summary: | Cyber security awareness has a huge impact on the increasing development of security products in the market. Considering the critical nature of the security products, information security is crucial due to interception and modification of data which can lead to loss of availability, integrity, and confidentiality, and possibly other losses such as loss of life, money, and assets. Thus, encryption is required for data protection and lightweight block cipher is identified as a solution to this security issue since it is more compact and requires small computing power. However, despite being lightweight, the trade-off between security and efficiency are the major problems to be solved in designing a lightweight algorithm. One should consider its type of circuit, speed, and memory consumption. Looking at this alarming situation, new solutions are needed to overcome security product issues. The research aims to develop a lightweight block cipher named Light Algorithm Operation (LAO-3D) based on 3-dimensional (3D) permutation. This method is composed of an array of plaintext that is performed on a 3D bits array that adds confusion and diffusion layer to strengthen the block cipher algorithm in terms of security and performance efficiency. In order to achieve the research objectives, the secure cryptographic components for lightweight block cipher are analysed in Phase 1 (Analysis) that can be used for future development of lightweight block cipher by cryptographic developers. In Phase 2 (Development), a new lightweight block cipher is designed that can be considered for implementation to solve security product issues. Meanwhile, cryptanalysis and software performance tests are carried out in Phase 3 (Evaluation) which can be used to distinguish the strength of lightweight block ciphers. Six cryptanalysis tests were conducted to assess the strength of LAO-3D. The findings suggested that LAO-3D achieved better results compared to other existing lightweight block ciphers with 98.2% correlation coefficient result, produced 50% results for both bit error rate and key sensitivity tests, passed 100% of the randomness test, and resistant to cryptanalysis attacks with the maximum number of rounds that can be attacked using differential and linear cryptanalysis are five and six rounds correspondingly. On top of that, LAO-3D obtained competitive performance results with 10.85% faster execution speed and produced 12.18% more throughput than the closest competitor. Overall, this research contributes to the field of cybersecurity supporting the Malaysian government’s initiatives in safeguarding the well-being of the people in line with the National Cyber Security Policy. |
