    摘要:

    为了解决现有安全接入区在设计和实现上困难、通用性差、传输效率低、安全性不足等问题,提出了基于双重隔离的电力通用安全接入区设计。该设计主要包含加密认证装置、正反向隔离装置和通用接入设备。在对现有安全接入区结构和原理分析的基础上,指出了其在实现上的不足。提出的安全接入区采用通用接入设备简化了安全接入区的设计,实现了通信双方的无感接入以及安全接入区的双重隔离和基于国密算法的加密和认证。测试及验证结果证明了该设计的可行性并给出了关键通信和安全参数的测试结果。与现有方案相比,该设计在通用性、性能和安全性上都得到了提高,具有较好的实用性。

    Abstract:

    In order to solve the problems in the design and implementation of current security access zone, such as poor universality, low transmission efficiency and lack of security, a design of power universal security access zone based on dual isolation is proposed. The design mainly includes the encryption and authentication device, the forward and reverse isolation devices and the universal access device. Based on the analysis of the structure and principle of the current security access zone, its shortcomings are given. By using universal access device, the design of security access zone is simplified, the no sense access of the two communication ends is realized, and the dual isolation of the security access zone and the encryption and authentication based on the state secret algorithm are realized. The results of test and verification prove the feasibility of the design and the test results of key communication and security parameters are given. Compared with the current schemes, the design has been improved in terms of universality, performance and security, and has good practicability.
