Simulating a Multi-domain RFID System for Replacement Part Tracking

The efficient and reliable handling of replacement parts is of high importance for airlines. It can be supported by attaching an RFID tag to replacement parts that stores data identifying unambiguously the replacement part and further information about its installation and maintenance. Security is essential so that only authenticated and authorized entities can read and modify data according to the defined access permissions. Although the information is managed in a decentralized way, it has anyhow to be synchronized with the airlines backend database finally.This paper describes data format, certificate management and access control when using these passive RFID tags in a multi-domain scenario for replacement part tracking within the avionics industry. The demonstrator architecture design is described for simulating replacement part tracking. It allows simulating use cases of the multi-domain RFID system for replacement part tracking. Both simulated and real RFID tags can be used in the simulation.
