With the interconnection of devices becoming more widespread in society (e.g. internet of things), networked devices are used in a range of environments from smart grids to smart buildings. Wireless Sensor Networks (WSN) have commonly been utilised as a method of monitoring a set processes. In control networks WSN have been deployed to perform a variety of tasks (i.e. collate and distribute data from an event to an end device). However, the nature of the wireless broadcast medium enables attackers to conduct active and passive attacks. Cryptography is selected as a countermeasure to overcome these security vulnerabilities; however, a drawback of using cryptography is reduced throughput. This paper investigates the impact of two software authenticated encryption with associated data (AEAD) security constructs on packet throughput of multiple hop WSN, being counter with cipher block chaining and message authentication code (CCM) and TinyAEAD. Experiments were conducted in a simulated environment. A case scenario is also presented in this paper to emphasise the impact in a real world context. Results observed indicate that the security constructs examined in this paper affect the average throughput measurements up to three hops.

“…Cryptography is selected to mitigate these attacks, however, the selection of the cryptographic algorithm had influenced the performance and operation of the UAV [3], [4]. The contributions of this paper are the permutation subsitution network (PSN) block cipher design paradigm, the alternative advanced encryption standard (AAES) and the first benchmark test between the substitution permutation network (SPN) and the PSN design paradigms.…”

A novel block cipher design paradigm for secured communication

2016 Annual IEEE Systems Conference (SysCon)

et al. 2016

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.

“…Cryptography is selected to mitigate these attacks, however, the selection of the cryptographic algorithm had influenced the performance and operation of the unmanned vehicle [3], [4]. As unmanned vehicles have limited energy supplies, the selection of standardised cryptographic approaches may not be suited for this context [5], [6].…”

LEOPARD: Lightweight Encryption Operation Permutation Addition Rotation and Diffusion

2016 10th International Conference on Signal Processing and Communication Systems (ICSPCS)

2016

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%.
