摘 要: | 无线传感器网络(WSNs)由于其通信信道的开放性、节点资源受限性和部署随机性等特点,其安全性面临很多挑战。针对某些部署在危险环境中的WSNs应用对安全性要求较高的问题,提出了一种兼具主、被动防御的WSNs安全通讯策略。通过对消息的加、解密,签名认证,完整性鉴别等主动防御措施和变换基站的被动防御措施相结合的策略,为网络创造一个相对安全的工作环境。性能分析表明:该策略能降低网络受到攻击的可能性,减小攻击影响,提高网络的抗毁能力,有效地延长网络的生命周期。

A security communication strategy for WSNs with both active and passive defenses |
| |
Abstract: | Because of its nature features such as openly communication channel, resource-constrained nodes and randomly deployment, the problem of security is facing challenge for wireless sensor networks. In this paper, a security communication strategy which possesses both active and passive defenses is proposed, for the problem of some applications of WSNs which are always placed in dangerous environment that requires high safety. By combining the technology of active defenses which adopt encryption, decryption technique, signature certification, integrity identify, and with passive defenses of transforming the base-station to create a relatively safe operate environment for network. The performance analysis shows this strategy can reduce the possibility of the network under attack, decrease the effect of attack, improve the network anti-dilapidated ability and prolong the lifetime. |
