摘要：As it is known, the researches on ownership transfer issues of RFID tag have focused on a single owner. However in practice, RFID tag may have multiple owners who occupy different weights. To solve the problem, the ownership transfer protocol of multi-owner with different weights based on Lagrange has been proposed. Assuming the key is divided into n parts in this paper, and the owner gets the corresponding sub secret key according to the weight. Then, If and only if the sum of the weights of the owners involved in the restoration of the secret key is equal to or greater than t, the secret key can be obtained, or not. Therefore, security of ownership transition and flexibility in the practical application are enhanced
