摘要

传统的动态异构冗余(DHR)架构存在执行器之间的稳定性差异和相似漏洞所造成的安全威胁。为了克服这些挑战,我们提出了一种智能 DHR 架构,通过智能地结合基于随机分布的动态调度算法(RD-DS)和基于信息权重和异构性的仲裁算法(IWHA),该架构更加可行。在所提出的架构中,利用随机分布函数和信息权重实现了 RD-DS 过程中执行器的最优选择,避免了传统 DHR 架构中部分执行器因稳定性差异而无法被选择的情况。然后,通过引入异质性来限制 IWHA 过程中的信息权重,所提出的架构解决了因相似漏洞存在多个相同错误输出结果而导致的共模逃逸问题。实验结果表明,在相同条件下,拟议架构在异构性、调度时间、安全性和稳定性方面均优于传统的 DHR 架构。

Intelligent dynamic heterogeneous redundancy architecture for IoT systems
The conventional dynamic heterogeneous redundancy (DHR) architecture suffers from the security threats caused by the stability differences and similar vulnerabilities among the executors. To overcome these challenges, we propose an intelligent DHR architecture, which is more feasible by intelligently combining the random distribution based dynamic scheduling algorithm (RD-DS) and information weight and heterogeneity based arbitrament (IWHA) algorithm. In the proposed architecture, the random distribution function and information weight are employed to achieve the optimal selection of executors in the process of RD-DS, which avoids the case that some executors fail to be selected due to their stability difference in the conventional DHR architecture. Then, through introducing the heterogeneity to restrict the information weights in the procedure of the IWHA, the proposed architecture solves the common mode escape issue caused by the existence of multiple identical error output results of similar vulnerabilities. The experimental results characterize that the proposed architecture outperforms in heterogeneity, scheduling times, security, and stability over the conventional DHR architecture under the same conditions.
