In order to solve the problems, a lightweight RFID authentication protocol supporting anonymity was proposed. Firstly, the random number generator was used to generate the unpredictable sequence for specifying the lightweight operators participating in the protocol. Then, the seed was specified to achieve the key negotiation between the reader and the tag. Finally, the mutual authentication and information updating were achieved. The comparison results with some representative lightweight schemes show that the proposed scheme saves the the tag storage overhead by up to 42% compared with the similar lightweight protocols, and the has the communication overhead also maintained at the low level of similar schemes at the same time, and is able to support the multiple security requirements. The proposed scheme is suitable for low-cost RFID systems. %U http://www.joca.cn/EN/10.11772/j.issn.1001-9081.2020121947
