Underwater wireless sensor networks (UWSNs) have emerged as the most widely used wireless network infrastructure in many applications. Sensing nodes are frequently deployed in hostile aquatic environments in order to collect data on resources that are severely limited in terms of transmission time and bandwidth. Since underwater information is very sensitive and unique, the authentication of users is very important to access the data and information. UWSNs have unique communication and computation needs that are not met by the existing digital signature techniques. As a result, a lightweight signature scheme is required to meet the communication and computation requirements. In this research, we present a Certificateless Online/Offline Signature (COOS) mechanism for UWSNs. The proposed scheme is based on the concept of a hyperelliptic curves cryptosystem, which offers the same degree of security as RSA, bilinear pairing, and elliptic curve cryptosystems (ECC) but with a smaller key size. In addition, the proposed scheme was proven secure in the random oracle model under the hyperelliptic curve discrete logarithm problem. A security analysis was also carried out, as well as comparisons with appropriate current online/offline signature schemes. The comparison demonstrated that the proposed scheme is superior to the existing schemes in terms of both security and efficiency. Additionally, we also employed the fuzzy-based Evaluation-based Distance from Average Solutions (EDAS) technique to demonstrate the effectiveness of the proposed scheme.
水下无线传感器网络（UWSNs）已成为许多应用中使用最广泛的无线网络基础设施。传感节点经常部署在恶劣的水生环境中，以便收集在传输时间和带宽方面严重受限的资源数据。由于水下信息非常敏感且独特，用户认证对于访问数据和信息非常重要。UWSNs有独特的通信和计算需求，现有数字签名技术无法满足这些需求。因此，需要一种轻量级签名方案来满足通信和计算要求。在本研究中，我们提出了一种用于UWSNs的无证书在线/离线签名（COOS）机制。所提出的方案基于超椭圆曲线密码系统的概念，该系统提供与RSA、双线性配对和椭圆曲线密码系统（ECC）相同程度的安全性，但密钥大小更小。此外，所提出的方案在超椭圆曲线离散对数问题下的随机预言模型中被证明是安全的。还进行了安全性分析，并与适当的当前在线/离线签名方案进行了比较。比较表明，所提出的方案在安全性和效率方面均优于现有方案。此外，我们还采用了基于模糊的离平均解评估距离（EDAS）技术来证明所提出方案的有效性。
