Abstract-Tactical unmanned vehicles are commonly used to conduct tasks (e.g. monitor and surveillance) in various civilian applications from a remote location. The characteristics of the wireless communication link allows attackers to monitor and manipulate the operation of the unmanned vehicle through passive and active attacks. Cryptography is selected as a countermeasure to mitigate these threats; however, a drawback of using cryptography is the impact on the energy consumed by the unmanned vehicle as energy is often constrained and limits the duration of the mission time. This paper introduces the Lightweight Encryption Operation Permutation Addition Rotation and Diffusion (LEOPARD) cryptographic primitive with a benchmark performance analysis against the standardised Advanced Encryption Standard (AES). Results indicate that LEOPOARD is a feasible encryption approach in comparison to the AES encryption algorithm for unmanned vehicles with an average performance increase of 8%.

Abstract-The flexibility and mobility of Mobile Ad hoc Networks (MANETs) have made them increasingly popular in a wide range of use cases. To protect these networks, security protocols have been developed to protect routing and application data. However, these protocols only protect routes or communication, not both. Both secure routing and communication security protocols must be implemented to provide full protection. The use of communication security protocols originally developed for wireline and WiFi networks can also place a heavy burden on the limited network resources of a MANET. To address these issues, a novel secure framework (SUPERMAN) is proposed. The framework is designed to allow existing network and routing protocols to perform their functions, whilst providing node authentication, access control, and communication security mechanisms. This paper presents a novel security framework for MANETs, SUPERMAN. Simulation results comparing SUPERMAN with IPsec, SAODV, and SOLSR are provided to demonstrate the proposed frameworks suitability for wireless communication security.

Abstract-Unmanned aerial vehicles (UAV) are commonly used to conduct tasks (e.g. monitor and surveillance) in various civilian applications from a remote location. Wireless communications (i.e. radio frequency) are often used to remotely pilot the UAV and stream data back to the operator. The characteristics of the wireless communication channel allows attackers to monitor and manipulate the operation of the UAV through passive and active attacks. Cryptography is selected as a countermeasure to mitigate these threats; however, a drawback of using cryptography is the impact on the real-time operation and performance of the UAV. This paper proposes the Permutation Substitution Network (PSN) design paradigm with an instance presented which is the Alternative Advanced Encryption Standard (AAES) and analysis of its performance against the standardised Substitution Permutation Network (SPN) design paradigm the Advanced Encryption Standard (AES). Results indicate that using the PSN paradigm is a feasible approach in comparison to the SPN design paradigm.
