摘要

無線射頻標籤技術已經廣範地用於企業管理。然而，應用在管理庫存時，只是掃描ID無法防範偽造的無線射頻標籤。因此群組證明協議被提出來證明多個標籤的同時存在性，提供數據證明。過去的研究存在一些限制，諸如協議產生過程需要由後端服務器發起、需要鏈狀的步驟或預先分類的群組。這些限制使得群組證明難以落實。在本文中，我們針對六個不同應用情境內的群組證明分組歸納為設計準則。我們提出兩個群組證明協議，讓讀取器能平行操作這些標籤，並降低了過去研究的諸多限制。

RFID technology has been adopted by enterprises for better management. However, in the inventory scenario, scanning IDs is not enough due to RFID counterfeiting. Grouping proof protocols were proposed to provide security tokens that prove the existence of multiple RFID tags at the same period of time. They have limitations such as continuous connection to the back-end server, sequentially chained steps and previously fixed group that make grouping proofs difficult to implement. In this paper, we addressed how to adopt grouping proofs in six different scenarios and summarized design guidelines for grouping proof protocols. We propose two grouping proof protocols that allow the reader to access tags in parallel and reduce restrictions of previous works.
