Securing OPEN-RAN Equipment Using Blockchain-Based Supply Chain Verification

arXiv:2402.17632v1 Announce Type: new
Abstract: The disaggregated and multi-vendor nature of OPEN-RAN networks introduces new supply chain security risks, making equipment authenticity and integrity crucial challenges. Robust solutions are needed to mitigate vulnerabilities in manufacturing and integration. This paper puts forth a novel blockchain-based approach to secure OPEN-RAN equipment through its lifecycle. By combining firmware authentication codes, a permissioned blockchain ledger, and equipment node validators, we architect a tamper-resistant ecosystem to track provenance. The outlined design, while conceptual, establishes a …
