Abstract:

A dynamic ownership transfer protocol of RFID tag based on Lagrange algorithm was proposed to achieve the transfer for multi-owner with different weights.When the ownership of a tag changed,the agreement could recover the original secret key to verify the legitimacy of the owners,and use secret sharing algorithm to redistribute sub-key according to the new weights of the owners to make the security and flexibility of the ownership transfer improved.The simulation is carried out to show that it adapts to a low-cost RFID tag because the calculation and time consuming are low in the protocol.

Key words: multi-owner, Lagrange algorithm, shared secret key, dynamic ownership transfer
