Multi-domain RFID applications, such as asset tracking across domains, shift the paradigm in business model and enable next-generation business processes for aviation industry. The increasing number of RFID applications also merits the consolidation of RFID tags so they can serve multiple purposes. However, the adoption of such multi-domain RFID applications depends on their ability to enforce access control to the tags that will be accessed by different stakeholders across multiple domains. This paper addresses multi-domain RFID access control. The paper evaluates existing solutions in the literature and identifies their limitations. The paper proposes using asymmetric key based tag-reader mutual authentication to grant only the authorized read/write access to tags.
