Multi-owner RFID Tag Ownership Transfer Protocol based on the Chinese Remainder Theorem

다국어 초록 (Multilingual Abstract)

For the security issue of the single tag ownership transfer, this paper proposes a multi-owner RFID Tag ownership transfer protocol based on the Chinese remainder theorem. By using secret sharing scheme, this protocol divides the sharing key into n parts, which then are distributed to n owners. Only when t owners cooperate together, the sharing key will be recovered. Thus, it ensures the tag’s security during the authentication and transformation of the ownership. Under the Linux environment, this protocol was achieved through simulationtest and the experiment data about the calculate time of the tag was got. Then with the number of owners increasing gradually, different results were compared. The result shows that in the protocol, when increasing the owners’ number, the calculate time of tag is in the acceptable range, which is also apply to the low cost tag.
