摘要
针对当前电力物联终端设备接入请求过多,导致终端单位吞吐量较低的问题,文章提出基于边缘计算的电力物联终端设备身份公钥安全接入方法。根据电力物联终端设备特征信息,获取设备指纹参数。以边缘计算体系为基础,设计较为简单的设备身份可信度评估方法,以边缘计算单元中的信任属性为基础进行局部计算,简化认证参数的容量。依托于终端签名技术,建立身份信息安全传递机制,结合标识密码认证算法,实现设备身份公钥安全接入。实验结果表明,所提接入方法的平均单位吞吐量为47000 kbit,得到了较大提升。
Aiming at the problem of low unit throughput due to excessive access requests for power IoT terminal equipments,a secure access method for ubiquitous power IoT terminal equipments based on edge computing is proposed.According to the characteristic information of the power IoT terminal equipment,the fingerprint parameters of the equipment are obtained.Based on the edge computing system,we design a simple equipment identity trustworthiness assessment method to simplify the capacity of authentication parameters by localizing the computation based on the trust attributes in the edge computing unit.Based on the terminal signature technology,the secure transmission mechanism of identity information is established,and the authentication algorithm of identity password is combined to realize the secure access of equipment identity public key.The experimental results show that the average unit throughput of the proposed access method is 47000 kbit,which is greatly improved.
