Abstract

The secure implementation of log management mechanisms in Internet access systems is crucial to ensuring the integrity, confidentiality, and availability of information. Access providers face challenges in meeting regulatory and compliance requirements, as logs can be altered, deleted, or disputed. These records play a fundamental role in audits, forensic investigations, and the establishment of security baselines. In this context, this paper presents the concept of proofs-of-connection for Network Access Auditing using blockchains. The performance evaluation examines log processing time for various batch sizes and analyzes the system’s average throughput (logs per second), considering the time required for hash generation, blockchain registration, and indexing. To assess multiple configurations, a queue model is used to provide quantitative results for different batch size settings.
