无线传感器网络需要广播的操作，如软件更新，网络查询和命令分发。除了确保源和数据的真实性外，保持广播数据的机密性在某些应用中至关重要，例如战场控制，应急响应和自然资源管理。在本文中，我们提出了一种机制，以确保在单跳网络的广播数据的机密性和真实性的原型，并讨论了可能的扩展到多跳设置。我们的方案使用已知的低复杂度对称加密技术的机密性，同时改变加密密钥的基础上，每个数据包在一个可验证的，但不可伪造的方式，以确保真实性。还提供了消息完整性、新鲜性和语义安全性，并且广播数据可以被动态地和增量地处理。我们将我们的安全方案到tinyOS，事实上的网络编程协议，并量化成本的广播数据传输时间和节点内存空间的TelosB基于微尘的平台。
Wireless sensor networks need broadcast for operations such as software updates, network queries, and command dissemination. Alongside ensuring authenticity of the source and data, keeping the broadcast data secret is vital in certain applications such as battlefield control, emergency response, and natural resource management. In this paper we propose and prototype a mechanism for ensuring confidentiality and authenticity of broadcast data in single-hop networks, and discuss possible extensions to multi-hop settings. Our scheme uses known low-complexity symmetric encryption techniques for confidentiality, while changing the encryption key on a per-packet basis in a verifiable but non-forgeable way to ensure authenticity. Message integrity, freshness, and semantic security are also provided, and the broadcast data can be dynamic and incrementally processed. We incorporate our security scheme into Deluge, the de facto network programming protocol in TinyOS, and quantify the cost in terms of broadcast data transfer time and node memory space on a TelosB mote based platform.
