Embodiment Construction

[0100] Attached below figure 1 , to further describe the specific steps of the present invention.

[0101] Step 1, initialize data.

[0102] Store the data A, B, C, and D to be initialized in the cloud server, the old owner reader, the new owner reader, and the group label, among which, the old owner reader and the new owner reader are both available mobile reader.

[0103] The data A stored in the cloud server to be initialized includes: the registered identity of the old owner reader on the cloud server, the index hash value used for searching, the encrypted group tag authentication information, the encrypted group tag’s corresponding commodity information, and the cloud The public-private key pair of the server.

[0104] The data B stored in the old owner's reader to be initialized includes: the registration identity of the old owner's reader on the cloud server, the identity of the old owner's reader, the identity of the group tag, the pair of symmetric encryption and d...

Abstract

The invention discloses a cloud-storing based radio frequency identification (RFID) group tag ownership transferring method which is carried out through the following steps: (1) initializing data; (2) using an old owner reader to obtain group tag information; (3) checking the integrity of group tag members; (4) using a new owner reader to obtain group tag information; (5) using a group tag to indirectly authenticate the old owner reader; (6) using the new owner reader to authenticate the group tag; (7)judging and comparing if the added-up number (m) is equal to the number (n) of group tag members; (8)using the group tag to authenticate the new owner reader; (9) transferring the ownership of the group tag; according to the method provided in the invention, a cloud server is adopted to store tag data, making the transferring of the ownership of a group tag free from geological restrictions. The method can be widely applied and is compatible with a mobile reader. With the method, the ownership of a plurality of tags can be transferred at a time. The method is characterized by high flexibility and high efficiency as well.

Description

technical field [0001] The invention belongs to the technical field of communication, and further relates to a cloud-based cloud storage radio frequency identification (Radio Frequency Identification, RFID) group tag ownership transfer method in the technical field of information security. The invention can realize the mutual authentication between the mobile reader and the cloud database server as well as between the mobile reader and the radio frequency group tag, thereby ensuring the safe transfer of ownership of the radio frequency group tag. Background technique [0002] At present, existing methods for transferring the ownership of radio frequency tags can be roughly divided into two categories: schemes with the participation of a trusted third party (Trusted Third Party, TTP) and schemes without the participation of a trusted third party. Among them, the ownership transfer protocol involving a trusted third party can achieve higher security, but increases the deployme...
