摘要
针对现有技术中网络安全防护技术滞后的问题,提出了新型的网络安全防护技术。根据电力物联网运行逻辑,分析感知层、网络层、平台层和应用层运行风险。确定安全防护整体性目标,利用纠删码技术构造编码函数,分析纠删码编码过程,采用Reed-Solomon码作为BCH码,以此纠正随机错误,得到生成矩阵。通过设置密钥认证机制,完成防护方案设计。试验表明,防攻击效率达到99%,防护效果好。
Aiming at lagging network security protection technology,a novel network security protection technology was proposed.According to the operational logic of the Power Internet of Things,operation risks of the perception layer,network layer,platform layer and application layer were analyzed.Overall goal of security protection was determined.Coding function was constructed by means of erasure coding and erasure coding process was analyzed.Reed-Solomon code was used as BCH code to correct random errors and obtain the generator matrix.A key authentication mechanism was set up to complete protection scheme design.The experiments showed that the proposed technology can achieve an anti-attack efficiency of 99%and produce good protection effects.
