中文摘要：
针对无线传感器网络（WSN）数据传输的特点,提出了一种WSN下虚拟多路径逐跳的数据源认证方案。方案中通过节点指定消息传送的第二跳节点,建立了两条虚拟路径,达到了对消息进行双重认证的效果。方案能够保证数据的机密性和完整性,并且能够有效地抵御捕获节点的攻击,在计算量和通信量上具有较高的效率。
英文摘要：
In order to adapt the trait of data transmission in WSN,a virtual 3-way hop by hop data communication scheme is proposed.When data is transmitted,a node cannot decide on the next node on the path by itself.This decision has been made already by the previous node.The protocol provides duple authentication during communication.It also achieves data confidentiality and integrity in the link.Analytical results show that the protocol is robust against compromised sensor nodes and efficient with low computation and storage overhead on the sensor nodes.
