无线传感器网络安全性分析
1)简介
随着无线传感器的持续发展和日益普及,有效安全机制的出现显得尤为重要。在当前的无线传感器安全领域还有很大的研究空间,因为要想解决如今存在的问题,还有不少花费少效率高的渠道等待我们发现。对传感器网络来说,安全性是极其重要的。因为它常要处理敏感数据或是在无人监管的情况下进行运作。自身的延展性和资源的限制使传感器网络的安全解决方案面临挑战。传统的电脑安全技术在应用于无线传感器网络时常因资源限制面临障碍,例如,缺乏数据存储和能源消耗过大等。除了像节点聚合的可信赖程度等这些传统安全问题之外,无线传感器网络其他方面的难题还有安全及有效路径的实现、数据聚合、团队形成等。针对无线传感器领域的其他安全因素,人们提出了对传感器进行物理攻击,用于利用不可靠的通信通道进行数据传输。无人监管操作的无线传感器的定义为:由微型传感器、促动器和通用计算机元件组成的异构系统。传感器网络集自我组织、低能源和低价的无线节点于一身。无线传感器在很多领域都得到了广泛应用,例如,防窃报警器、库存控制、医疗监测和应急响应系统、边远地区居民监测、战场上的目标跟踪、赈灾网络、早期森林火灾和环境监控等。

SECURITY IN WIRELESS SENSOR NETWORKS
1)简介——INTRODUCTION:
As wireless sensor networks continue to grow and gaining in popularity, so the need for effective security mechanisms. There are currently large researches potential in the field of wireless sensor network security .The reason for the increase in its popularity due to the potentially low cost solution to the numerous types of real world challenges .Security in the senor networks is major issues as it deals with sensitive data or operative in unattended environments. Scalability and limited resources make security solutions challenging in the wireless sensor networks. Traditional computer security techniques in a wireless sensor networks faces many obstacles to the implementation due to resource constraints like lack of data storage and power consumption Some aspects of wireless sensor network, challenges are secure and efficient routing, data aggregation ,group formation and in addition to these tradition security issues like nodes are cooperative and trustworthy. Many more security issues in the field of wireless sensor networks argue the physical attacks to sensor play, many attacks designed to exploit the unreliable communication channels, unattended operation of wireless networks Sensor networks are defined to the heterogeneous systems with tiny sensors and actuators with general purpose computing elements. Sensor Network is combination of self organizing, low power, and low cost wireless nodes. Sensor Networks are used in many application /fields and are as follows burglar alarms ,inventor control ,medical monitoring and emergency response ,monitoring remote or inhospitable habitants ,target tracing in the battle field, disaster relief networks, early fire detection in forest and environmental monitoring. These demand very demanding environment to provide security. Secure routing secure discovery verification of location, key managements are the most issues which face the many security challenges
Security challenges in WSN's:
* Data confidentiality
* Data integrity
* Authentication
* Key establishment
* Availability
* Privacy
* Secure routing
* Secure group management
* Intrusion detection
* Secure data aggregation
Attacks on WSN's
Common Attacks: As the wireless medium is used as the main transmission hannel in WSN, it is easily subject to various types of attacks, either passive (eavesdropping) or active (data injection).
Denial of Service Attacks (DoS): These attacks prevent any part of WSN from functioning correctly
