摘　　要：针对端到端无线通信建链缺乏安全保护,因窄带宽而无法套用常规方法的问题,提出了一种自准备、自维护的建链加密方法。该方法以预存公钥全集、少许对称密钥为起点,辅以滚动、扩散以适应新增设备、带宽恶化等变化。最终,该方法利用端设备有限的密钥存储空间,实现了低成本、可扩展、自动化的窄带建链加密保护。To address the problem that end-to-end wireless communication link building lacks security protection and cannot apply conventional methods due to narrow bandwidth,this paper proposes a selfpreparing and self-maintaining link building encryption method.The method starts with the complete set of pre-stored public keys and few symmetric keys,supplemented by rolling and diffusion keys to adapt to new devices,bandwidth degradation and other changes.Finally,this method uses the limited key storage space of end devices to achieve low-cost,scalable and automated narrowband link building encryption protection.
