Abstract

The invention relates to the technical field of information security, in particular to an electronic tag ownership transfer method based on TTP. A block rearrangement algorithm Br (X, Y) adopted by the method comprises the following steps of: respectively blocking an operand X and an operand Y to obtain a first operation set and a second operation set with n elements, wherein the operand X is any one of the keys, and the operand Y is a corresponding random number; corresponding elements in the first operation set and the second operation set according to a preset rule to obtain Hamming weights of the corresponding elements; performing cyclic right shift on each element in the first operation set and the second operation set by the digit of the Hamming weight of the corresponding element to obtain an operand X' and an operand Y'; and performing XOR on the operand X' and the operand Y' to obtain an encryption result. The block rearrangement algorithm conforms to the lightweight standard and has high irreversibility, and the technical problems that in the prior art, a label ownership transfer protocol cannot provide forward privacy security and is prone to being subjected to desynchronization attacks and Dos attacks are solved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a TTP-based electronic label ownership transfer method and system. Background technique [0002] RFID radio frequency identification technology is a key technology in the sensing layer of the Internet of Things. Barcodes for optical scanning require contact with the reader within the line of sight. On the contrary, RFID tags can identify and scan without line of sight contact and without precise positioning. In addition, RFID tags can be scanned by readers hundreds of times per second. RFID tags have obvious advantages in both the flexibility of identification and the efficiency of identification. Although the use of RFID tags brings convenience, it also needs to solve the security and privacy issues existing in wireless transmission between readers and tags. Tag ownership refers to the owner's ability to control access to read and write tags. The transfer of good...
