Security issues in wireless sensor networks

摘要: Providing security to wireless sensor networks is very challenging, as they include protection against damages, losses, attacks, and dangers. Moreover, a node has limited computation power, memory, I/O resources. The classic issues that are usually considered in upholding the secrecy avoiding intrusion. Securing access general difficult task when compared fixed/wired because use transmission medium. WSNs more challenging than for traditional networks. This mainly due resources of harsh working environments these systems most cases. In this chapter, we present key issues, challenges, vulnerabilities, existing solutions, comparison major techniques related WSNs. Background general, heterogeneous systems. They contain general-purpose computing elements with actuators tiny sensors. have computational bandwidth, peripherals. These aspects make it design secure WSN system [1–71], secured schemes require large power consumption, among other providing not an easy resource limitation on nodes, high risk physical density size networks, unknown topology prior deployment, also nature characteristics communication channels.
