Abstract：As most ownership transfer protocols of RFID tags were subject to no independence of the original owner and security privacy issues,the RFID tags ownership dynamic transfer protocol of multi-owner with trusted third party (TTP) weights was proposed based on Lagrange polynomial interpolation algorithm.In the protocol,the new owner would obtain the original subkey and weight from the original owner in the way of purchasing,the legality of the original owner and the new owner were verified by recovering the original key and TTP,and the subkey was distributed according to the weight of the new owner by using the secrete sharing scheme.The simulation result showed that the protocol significantly improved the security of ownership transfer,and the calculation quantity and time-consuming were within the acceptable scope,which was applicable to the low cost tag.
