In the wireless sensor network(WSN) security is a major issue. There are several network security schemes proposed in research. In the network, malicious nodes obstruct the performance of the network. The network can be vulnerable by Sybil attack. When a node illicitly assertions multiple identities or claims fake IDs, the WSN grieves from an attack named Sybil attack. This attack threatens wireless sensor network in data aggregation, synchronizing system, routing, fair resource allocation and misbehavior detection. Henceforth, the research is carried out to prevent the Sybil attack and increase the performance of the network. This paper presents the novel security mechanism and Fujisaki Okamoto algorithm and also application of the work. The Fujisaki-Okamoto (FO) algorithm is ID based cryptographic scheme and gives strong authentication against Sybil attack. By using Network simulator2 (NS2) the scheme is simulated. In this proposed scheme broadcasting key, time taken for different key sizes, energy consumption, Packet delivery ratio, Throughput were analyzed.
在无线传感器网络（WSN）中，安全是一个主要问题。研究中提出了几种网络安全方案。在网络中，恶意节点会阻碍网络性能。网络可能会受到女巫攻击的影响。当一个节点非法宣称多个身份或声称虚假身份时，无线传感器网络就会遭受一种名为女巫攻击的攻击。这种攻击在数据聚合、系统同步、路由、公平资源分配和行为不当检测方面威胁着无线传感器网络。因此，开展了相关研究以防止女巫攻击并提高网络性能。本文提出了新颖的安全机制和富崎-冈本算法以及该工作的应用。富崎-冈本（FO）算法是一种基于身份的加密方案，能有效抵御女巫攻击。通过使用网络模拟器2（NS2）对该方案进行了模拟。在这个提出的方案中，分析了广播密钥、不同密钥大小所需的时间、能耗、数据包交付率和吞吐量。
