A new lightweight RFID grouping authentication protocol for multiple tags in mobile environment (vol 76, pg 22761, 2017)

Radio Frequency Identification (RFID) is a promising technology in logistics management of mobile environment. Due to the practical prospects of low-cost RFID tags, multiple tags authentication remains an interesting topic. However, because of the resource restriction of low-cost tags, security and privacy risks remain crucial issues. Lots of research findings have been made emphasizing on the arrangement where single object to be verified is combined with only one tag, while the scenario that one object is attached with multiple tags is out of consideration, especially the authentication of large-size objects. In this paper, a new lightweight RFID grouping authentication protocol for multiple tags in mobile environment is proposed. A number of tags are attached to different parts of the large-size object. The proposed protocol can tolerate missing tags. The tags that do not respond will not disturb the entire authentication process, which guarantees that the object can be timely verified. Moreover, the security analysis shows that this protocol can offer sufficient security assurances and resist various attacks. Besides, the proposed protocol has better performance in terms of the execution time compared to previous studies.
