相邻传感器之间的密钥建立是无线传感器网络（WSN）中的身份验证和机密性等安全服务最具挑战性的问题。最近提出了许多密钥建立方案，但大多数都存在安全或性能问题。在本文中，我们提出了一种适用于低资源传感器节点的新型密钥建立协议。在该协议中，每个传感器都有一个秘密密钥和一些与其他传感器的公共密钥。两个传感器之间的公共密钥是使用一个传感器的秘密和另一个传感器的身份生成的。该密钥存储在其中一个传感器中，另一个传感器在需要安全连接时生成该密钥。我们为不同的密钥分发模型开发了拟议的协议。这些模型使用预部署知识在传感器之间分配公共密钥。基于连接性、可扩展性、内存消耗和抗攻击性对所提出的方案进行了分析。与以前的方法相比，所提出的协议对于受损节点攻击最具弹性。此外，它的内存需求低，计算开销也低。
Key establishment among neighboring sensors is the most challenging issue for security services such as authentication and confidentiality in wireless sensor networks (WSNs). Many key establishment schemes have recently been proposed, but most have security or performance issues. In this paper, we propose a novel key establishment protocol which is suitable for low resource sensor nodes. In this protocol, each sensor has a secret key and some common keys with other sensors. A common key between two sensors is generated using the secret of one sensor and the identity of the other. This key is stored in one of the sensors, and the other sensor generates it when a secure connection is required. We develop the proposed protocol for different key distribution models. These models use pre-deployment knowledge to distribute the common keys among sensors. The proposed scheme is analyzed based on connectivity, scalability, memory consumption and resistance against attacks. In comparison with previous approaches, the proposed protocol is the most resilient against compromised node attacks. In addition, it has low memory requirements and low computational overhead.
