On the Power Consumption of Security Algorithms Employed in Wireless Networks

Abstract

Supporting high levels of security in wireless networks is a challenging issue because of the specific problems this environment poses; the provided security by small mobile systems, such as PDAs and mobile phones, is often restricted by their limited battery power and their limited processing power. Driven by these restrictions, the designer will have to decide whether to implement the wireless network security schemes in software or to add special purpose hardware units to the system, executing those CPU intensive tasks. This paper demonstrates and compares the Hardware and Software implementations of a number of widely used security applications employed in wireless networks. We measured the total energy consumption for each security algorithm when implemented in reconfigurable hardware devices and we compared it with the total energy consumption of the equivalent software applications. We demonstrate, that the hardware implementations on a state-of-the-art FPGA are significantly faster while they consume three orders of magnitude less power when compared with the software implementations executed on a state-of-the-art hard-core CPU which is embedded in the same FPGA device.

Trust management in wireless sensor networks

“…Thus, all network nodes participate in the trust evaluation process playing a different role. This approach is also followed in References [15] and [16] where a three-tier network architecture (sensor nodes, cluster head, base station/command node) is considered. All nodes evaluate the trust of the cluster head and the relevant value is reported in the base station.…”

“…Likewise in [29], Masoud et al performed the power consumption from devices of various configuration in comparison to different applications like music, video, games etc. The comparison among various encryption algorithms performed in [30] for the power consumption of varied file sizes. The power consumption of software and hardware implementations of security algorithms executed in [31] and they concluded that hardware FPGA implementations proved to be much faster than the software implementation.…”

“…For example, encryption is a powerful technique against data privacy attack while authentication is a well-established solution to Sybil attack. However, the implementation of such security measures comes at a high cost since it requires significant memory and processing resources increasing at the same time the power consumption [52]. Focusing on routing attacks, a malicious node may refuse to forward all or part of the received traffic towards the destination (issuing a black-hole or grey-hole attack) exhibiting selfish behaviour.…”
