In an underwater environment, wireless sensor networks (WSNs) have more potential applications such as homeland safety, naval surveillance, and pollution & exploration monitoring. Underwater wireless sensor networks (UWSNs) help in decreasing the rate of causalities and provide efficient ways for monitoring the underwater activities of the other countries. UWSNs can be efficiently used by the navy to monitor suspicious activities and also to counter-attack any terrorist or enemy attacks. As usual, deploying wireless sensor networks underwater is not only challenging due to environment and constrained resources but also is vulnerable to security attacks. Thus, security is an unexplored and crucial aspect of UWSNs. Here, we define a node authentication mechanism for UWSNs for securing frontier lines, maritime territory, and naval surveillance. The proposed authentication protocol is based on symmetric-key cryptography and secures against impersonation, masquerade, Sybil, and many more other attacks. We have analyzed the proposed protocol both formally and automatedly and were unable to find any possible security attack on the proposed protocol. The experimental analysis of the mechanism proved that the proposed mechanism consumes less energy compared to the existing mechanisms. Hence, the proposed mechanism can be easily adopted for maintaining the security of maritime territory and reduce the causalities in naval operations.

使用无线传感器网络的海军行动中的海上领土和边境监视安全机制

在水下环境中，无线传感器网络 (WSN) 具有更多潜在应用，例如国土安全、海军监视以及污染和勘探监测。水下无线传感器网络 (UWSN) 有助于降低事故发生率，并为监测其他国家的水下活动提供有效方法。海军可以有效地使用 UWSN 来监视可疑活动并反击任何恐怖分子或敌人的袭击。像往常一样，在水下部署无线传感器网络不仅由于环境和资源受限而具有挑战性，而且容易受到安全攻击。因此，安全性是 UWSN 的一个未开发且至关重要的方面。在这里，我们为 UWSN 定义了一个节点身份验证机制，用于保护边境线、海域和海军监视。提议的身份验证协议基于对称密钥密码术，可防止假冒、伪装、女巫和更多其他攻击。我们已经正式和自动地分析了提议的协议，并且无法发现对提议的协议的任何可能的安全攻击。对该机制的实验分析证明，与现有机制相比，所提出的机制消耗更少的能量。因此，建议的机制可以很容易地用于维护海上领土安全并减少海军行动的伤亡。我们已经正式和自动地分析了提议的协议，并且无法发现对提议的协议的任何可能的安全攻击。对该机制的实验分析证明，与现有机制相比，所提出的机制消耗更少的能量。因此，建议的机制可以很容易地用于维护海上领土安全并减少海军行动的伤亡。我们已经正式和自动地分析了提议的协议，并且无法发现对提议的协议的任何可能的安全攻击。对该机制的实验分析证明，与现有机制相比，所提出的机制消耗更少的能量。因此，建议的机制可以很容易地用于维护海上领土安全并减少海军行动的伤亡。
