Abstract

The security of operation and maintenance phase in systems that share long-life cycles like weapon systems is of great importance. Even if the system passes the security evaluation at the development stage before release, it can be adversely affected by the penetration of counterfeit components (parts) during the operation and maintenance phase. Such security issues are concatenated with data related to supply chain, accordingly, system parts need to fulfill the traceability on a fundamental basis. In addition to traceability, supply chains should also meet the data security standards of availability, integrity and confidentiality in the long run. Also, even without trusted third party, these data should be available to users. In this paper, we, therefore, propose a framework that utilizes blockchain and key escrow encryption system in a bid to optimize the security of supply chains for long-lifecycle systems and provide better measures to improve services for global business survivability.
