The Research Of Wireless Sensor Network Security Support Technology

Wireless sensor network is a cross-disciplinary, involving computers. microelectronics, sensors, networks, communications, signal processing and other fields, is the automation, communications engineering and computer science and technology disciplines in a new research area, with wide application prospects. As sensor networks continues to apply in various fields, its security issues become increasingly prominent. Sensor networks used in wireless communications, channel lack the necessary shielding and protection to make it more vulnerable to attacks and eavesdropping. Due to resource-constrained sensor networks, traditional encryption,decryption can not be directly applied to the sensor network.This requires the need to design appropriate to meet the practical application of wireless sensor network security solutions and the corresponding key management scheme to enhance the sensor network security mechanism.This paper introduces the sensor network, based on the knowledge to study the sensor network security technologies and operating systems necessary for energy analysis. Main tasks are as follows:â‘ According to the wireless sensor network architecture and characteristics analysis of sensor networks face a variety of attacks and security issues, combined with the inherent characteristics of sensor networks proposed security needs.â‘¡Analysis of the sensor network key management features of the program and indicators. focused on the current use of the more extensive the key pre-distribution mechanism, its advantages and disadvantages compared.â‘¢This paper presents a wireless sensor network for the key pre-distribution scheme,And the program characteristics and indicators of the analysis and evaluation.â‘£According to the program's energy consumption standards for sensor networks through the embedded operating system TinyOS open-source analysis, demonstrating the program's design and simulation of the key pre-distribution scheme given node energy loss carried out a preliminary study. Ideas used in this paper and the proposed algorithm has a certain relevance, to a certain extent, inable ensure the security of sensor networks.Sensor network security involves more extensive knowledge, this article mainly one of the key management, key pre-distribution mechanism, based on the TinyOS energy loss in doing analysis and research program are given full consideration the limited resources of the sensor network characteristics, greatly enhanced the anti-node sensor network capture performance, and the link in the security establishment in the identification of forged nodes, effectively improves the security of sensor networks.
