中文摘要:

低压台区“源网荷储”友好互动带来用户侧智能控制设备、传感器接入需求，迫切需要面向本地HPLC+RF自组织网络技术体制，设计针对外部设备接入的安全高效身份认证方法。文中提出一种适应自组织网络的、去中心化的安全认证方案，通过台区边设备、可信代理、端设备建立本地认证链，相比现采集终端到主站的集中式认证方式，该方案可以有效降低因本地自组网网络层级加深而不断增长的安全交互开销，同时有效抵御本地自组织网络多级中继节点被挟持、流量嗅探等网络攻击。通过模拟低压台区本地自组织网络不同中继深度、不同规模外部设备接入多种场景，仿真计算获得外部设备接入台区本地通信网络安全认证交互所消耗通信资源定量分析结果，通过对比集中式认证方式，文中所提认证方案的平均资源消耗量可降低25%，且随着网络拓扑与终端规模的增长，通信资源节省效果更加明显。

英文摘要:

The friendly interaction of " source-network-load-storage" in low-voltage station area brings the demand for user-side intelligent control equipments and sensors access, so it is urgent to design a secure and eficient identity authentication method for external equipments access in local HPLC + RF Adhoc network. In this paper, a decentralized security authentication scheme adapted to Adhoc network is proposed. Local authentication chain is established through edge devices, trusted agents and terminal devices. Compared with the current centralized authentication method, the proposed scheme can effecivelye reduce the increasing security interaction cost caused by the deepening of the local Adhoc network level. It also effetively defends against network attacks , such as hijacking, taffic sniffing. By simulating various scenarios in which external devices of different relay depths and scales of equipments, the quantitative results of communication resources consumed by the security authentication interaction in the local communication network of external devices are obtained. By comparing the centralized authentication method , the average resource consumption of the proposed authentication scheme can be reduced by 25%. With the increase of network topology and terminal size, the effect of saving communication resources is more obvious.
