TEST PLATFORM FOR SECURE WIRELESS COMMUNICATION USING XTEA
Abstract:- In this paper we present a new methodology for the integration of security provisions into protocols for wireless sensor networks. There is an ever-growing demand for security in communications in general. As wireless sensor networks (WSN) face real-world applications the authenticity of the retrieved data has to be guaranteed. To facilitate integration of security provisions into WSNs the platform TAP-SNS (Testing Algorithms and Protocols for Sensor Network Security) enables the co-design of secure communication protocols between an x86-architecture and an embedded sensor node platform. Due to the co-design feature of the proposed platform, the use of freely available ANSI C implementations of cryptographic algorithms is made possible. As the system is OSI-model-based, it offers the exchange of whole layers (e.g. serial comport PHY to RF-Link PHY) without the need to adapt the software for the upper layers. The usage of this platform is demonstrated by means of the design of an authenticated broadcast protocol for an application of WSNs in logistics
