面向云端拜占庭故障的列控应用安全计算架构
Secure Computing Architecture for Cloud-Based Train Control Applications Under Byzantine Faults
摘要
Abstract
Cloud-native train control applications face security challenges such as logic hijacking,timing attacks,and Byzantine failures in open computing environments.To address these issues,this paper proposes a Logic-Temporal Dual-Dimension Verification(LTDV)architecture.The proposed architecture leverages Paillier homomorphic encryption to construct a logic evidence chain for verifying the integrity of program control flow,employs a temporal hash chain to bind timestamps for ensuring real-time behavior,and implements a result-driven filtering-based majority voting mechanism to achieve lightweight Byzantine fault tolerance.Experiments conducted on a cloud-based train control simulation platform for temporary speed restriction scenarios demonstrate that the proposed architecture effectively detects various types of typical attack scenarios,achieving an average detection rate of 97.8%and a false positive rate of less than 0.1%under normal operating conditions.Meanwhile,the system latency remains stable at the hundreds of milliseconds level,ensuring controlled overhead.Overall,the proposed architecture significantly enhances the trustworthiness of cloud-based train control computing within the constraints of millisecond response times,offering promising prospects for practical engineering deployment.关键词
