A Study of Offline Grouping Proof Protocol for Lightweight RFID Tags

The purpose of this study is to propose a mechanism with modified grouping proof technologies to guarantee the integrity and confidentiality of a set of Radio-Frequency Identity (RFID) tags. In some cases, the correctness and integrity are the most important than other. This mechanism is robust and compatible with EPCglobal Class-1 Generation-2 standard. Due to the light-weight computing abilities of passive RFID tags, especially to the most common standard today, we designed a novel grouping proof protocol using C1G2 build-in features that guarantee the correctness and integrity of a group of tags. Instead of the consideration of security strength against to various attacks, the correctness and integrity of a group of items are our major concerns here.
