一個使用於2G-RFID-Sys的安全基礎架構設計

Abstract

RFID is a mature technology in identification application based on Internet of Things (IoT). On the other hand, the traditional RFID system may suffer from the availability and scalability. Without the disadvantage of centralized management, a new type of RFID application named 2G-RFID-Sys will be more efficient. It can continue to provide services, even if the backend system is disconnected or unavailable. However, the validity and legitimacy of the executed data in the tag are not addressed in the original design of 2G-RFID-Sys. Besides, it lacks an infrastructure if it will be applied to an environment. The infrastructure has to be adjusted when it faces different environments. In this study, a 3-role-layer infrastructure of 2G-RFID-Sys is proposed. The prototype of 2G-RFID-Sys and the responsibility of each participant are refined. We apply it to manage the tagged objects in a huge range such as ambulance dispatch, cold chain system and certificate verification. In Medical Emergency System, we apply the infrastructure to the ambulance dispatch. The proposed protocol will ensure the traffic condition of the ambulance and increase a patient’s chance of survival. In the cold chain system, a Refined Smart Cold Chain System (RSCCS) was proposed in which the semi-passive tags are replaced with the passive tags to reduce the cost. The number of temperature sensors can be reduced to a minimum with a reader locally. In order to avoid vicious competition on business, our design can prevent the food information from being tampered. Not only the food producer can ensure the food freshness but also the consumer can safely purchase the products via RSCCS without accessing the backend system. For the demand of international talent, a global certificate verification mechanism with RFID-embedded technology is proposed. Without the factor of localization, it is a more flexible solution based on 2G-RFID-Sys to meet the transnational demand. 2G-RFID-Sys facilitates the system’s operations to perform actions on demand for different objects in different situations, and improves scalability. In summary, our proposal keeps the advantage of the original 2G-RFID-Sys and further ensures the correctness of the system execution.
