Agriculture plays an important role for many countries. It provides raw materials for foodand provides large employment opportunities for people in the country, especially for countrieswith a dense population. To enhance agriculture productivity, modern technology such as wirelesssensor networks (WSNs) can be utilized to help in monitoring important parameters in thwagricultural field such as temperature, light, soil moisture, etc. During the monitoring process, ifsecurity compromises happen, such as interception or modification of the parameters, it may leadto false decisions and bring damage to agriculture productivity. Therefore, it is very important todevelop secure authentication and key agreement for the system. Recently, Ali et al. proposed anauthentication and key agreement scheme using WSNs for agriculture monitoring. However, it failsto provide user untraceability, user anonymity, and session key security; it suffers from sensor nodeimpersonation attack and perfect forward secrecy attack; and even worse has denial of service as aservice. This study discusses these limitations and proposes a new secure and more efficientauthentication and key agreement scheme for agriculture monitoring using WSNs. The proposedscheme utilizes dynamic pseudonym identity to guarantee user privacy and eliminates redundantcomputations to enhance efficiency.
农业对许多国家都起着重要的作用。它为食品提供原材料，并为国家的人们提供大量的就业机会，尤其是人口密集的国家。为了提高农业生产力，可以利用现代技术（如无线传感器网络（WSN））来帮助监测农业领域的重要参数，如温度、光照、土壤湿度等。在监测过程中，如果发生安全漏洞，如参数的拦截或修改，可能会导致错误的决策，并对农业生产力造成损害。因此，为系统开发安全的认证和密钥协议非常重要。最近，Ali 等人提出了一种使用 WSN 进行农业监测的认证和密钥协议方案。然而，该方案未能提供用户可追踪性、用户匿名性和会话密钥安全性；它容易受到传感器节点伪装攻击和完美前向保密性攻击；更糟糕的是，它还存在拒绝服务攻击。本研究讨论了这些限制，并提出了一种新的用于 WSN 农业监测的安全且更高效的认证和密钥协议方案。该方案利用动态假名身份来保证用户隐私，并消除冗余计算以提高效率。
