Abstract:

Aiming at the conflict of the storage cost, the update frequency in P₁ and the de-synchronizing defect in P₂, an improved scalable radio frequency identification tag (RFID) ownership transfer protocol-lightweight scalable desynchronizing attack resistant protocol (LSDARP) was proposed. By the mechanism of sliding windows, the scheme only stores the tag's old and new adjacent eigenvalues to reduce the storage cost and avoid search efficiency degeneration when a group of eigenvalues was used out. It can be also re-synchronized when suffering de-synchronizing attacks continuously. Comparative analysis shows that LSDARP performs very well in aspects of the storage cost, computational complexity, backward security, de-synchronizing attack resistant and Tag Killing resistant.

Key words: ownership transfer, scalability, desynchronizing attack, radio frequency identification tag protocol
