🤖 AI Summary
To address inherent deficiencies in log management for distributed systems—specifically tamper resistance, scalability, and real-time performance—this paper proposes a blockchain-based log auditing framework tailored for large-scale deployments. The approach employs a hybrid on-chain/off-chain architecture: on-chain smart contracts automate log validation, enforce fine-grained access control, and anchor cryptographic hash timestamps; off-chain logs are stored immutably in IPFS, with zero-knowledge proofs enabling privacy-preserving, regulatory-compliant verification. Experimental evaluation demonstrates sustained throughput exceeding 10⁴ logs per second, support for over ten million logs, end-to-end latency under 200 ms, and a 67% reduction in storage overhead. The framework fully satisfies audit requirements of China’s Multi-Level Protection Scheme (MLPS) Level 3 and the EU’s General Data Protection Regulation (GDPR).
📝 Abstract
Log management is crucial for ensuring the security, integrity, and compliance of modern information systems. Traditional log management solutions face challenges in achieving tamper-proofing, scalability, and real-time processing in distributed environments. This paper presents a blockchain-based log management framework that addresses these limitations by leveraging blockchain's decentralized, immutable, and transparent features. The framework integrates a hybrid on-chain and off-chain storage model, combining blockchain's integrity guarantees with the scalability of distributed storage solutions like IPFS. Smart contracts automate log validation and access control, while cryptographic techniques ensure privacy and confidentiality. With a focus on real-time log processing, the framework is designed to handle the high-volume log generation typical in large-scale systems, such as data centers and network infrastructure. Performance evaluations demonstrate the framework's scalability, low latency, and ability to manage millions of log entries while maintaining strong security guarantees. Additionally, the paper discusses challenges like blockchain storage overhead and energy consumption, offering insights for enhancing future systems.
