A New Ownership Transfer Protocol for RFID Tags

【Abstract】 Aiming at the problem of the tag’s ownership safe transfer during its lifetime,an ownership transfer protocol for Radio Frequency Identification(RFID) is proposed,which is based on the Hash function without the Third Trust Party (TTP). It adopts the challenge-response mechanism,and uses the Status flag to indicate the tag’ s owner. In this protocol,the previous owner and the new owner share different secret keys with the target tag respectively, with communication information transferred between them,and the entities in systems can be authenticated. After a serious of authentication,the new owner obtains the ownership of the target tag. Analysis result shows that the protocol can satisfy the proposed security requirements for tag ownership transfer. The target tag is owned by the previous owner,and only owned by the new owner after the protocol’ s execution. So it can make the tag’ s ownership transfer exclusively. Compared with the previous works,the protocol’s performances on security and implementations are improved.
