A Dynamic Join-leave Multi-purpose Scheme for RFID Infrastructure

Abstract

Previously, a multi-purpose RFID tag needs one purpose stored one key in the tag and server, otherwise there will be security issues. In this paper, we propose a scheme for multi-purpose RFID tags. In this scheme, user can dynamic join-and-leave the purposes in multiple applications. Moreover, just authorized tags can be accessed. Our scheme is capable of applying multi-purpose tags, and we just need to store one key in a tag. Our approach will not cause the large computations of the database.
