“…From the below table that summarizes the set of hardware implementations of ECC in WSN already detailed in the previous sub-section, binary fields is used in the majority of implementations [36]- [39], [41], [42] and few over primary field F p [28], [40] [42] is the fastest with 84µs for point multiplication and relatively less consuming energy with 55µW comparing it with other primitives. Implementation in [38] performed ECC operation with area, time and consumption trade-off that are respectively 8104 gates, 115ms and 30µW.…”

“…Implementation in [38] performed ECC operation with area, time and consumption trade-off that are respectively 8104 gates, 115ms and 30µW. For WSN security, although most of the reviewed implementations were implemented on Application Specific Integrated Circuits (ASIC) [28], [36]- [39], [42], ECC can be implemented in FPGA [40], [41]. The lack of these works is the fact that most of them not implement the full scheme of key exchange and authentication with respectively ECDH and ECDSA which allows to strengthen the security of WSN and to resolve some constraints found in software implementation such as power, performance and area.…”

Abstract-In spite of previous widely held belief of the incompatibility of public key cryptography (PKC) schemes for wireless sensor networks (WSNs), some recent works have shown that, PKC based schemes could be implemented for such networks in some ways. The major challenge of employing a PKC scheme in wireless sensor network is posed by the limitations of resources of the tiny sensors. Considering this feature of the sensors, in this paper, we propose an efficient PKC based security architecture with relatively less resource requirements than those of the other previously proposed PKC schemes for WSN. Our security architecture comprises basically of two parts; a key handshaking scheme based on simple linear operations and the derivation of decryption key by a receiver node. Our architecture allows both base-station-to-node or node-to-base-station secure communications, and node-to-node secure communications. Analysis and simulation results show that, our proposed architecture ensures a good level of security for communications in the network and could effectively be implemented using the limited computation, memory and energy budgets of the current generation sensor nodes.

Enforcing patient privacy in healthcare WSNs through key distribution algorithms

Patient data privacy, as one of the foremost security concerns in healthcare applications, must be enforced through the use of strong cryptography. However, in the scenario where the patient wears a body network in which lightweight, battery-operated wireless sensors monitor various health variables of interest, the requirements for strong cryptography must often be balanced against the requirements for energy efficiency. In this paper, we describe two algorithms for key distribution. The first algorithm relies on a central trusted security server (CTSS) to authenticate that participants indeed belong to the patient's group and to generate the session key. In the second algorithm, participants authenticate each other using certificates and are largely independent of the central trusted security server (CTSS); this algorithm uses elliptic curve cryptography (ECC) to reduce energy consumption by cryptographic computations. In both cases, the patient's security processor has a lead role in authenticating group membership and the key generation process. Using the data from commercial devices compliant with the IEEE 802.15.4 low data rate WPAN technology, we show that this approach can be successfully implemented in networks built with low power motes.
