Cloud computing provides powerful pro-cessing capabilities for large-scale intelligent Internet of things (IoT) terminals. However, the massive real-time data processing requirements challenge the exist-ing cloud computing model. The edge server is closer to the data source. The end-edge-cloud collaboration offloads the cloud computing tasks to the edge envi-ronment, which solves the shortcomings of the cloud in resource storage, computing performance, and en-ergy consumption. IoT terminals and sensors have caused security and privacy challenges due to resource constraints and exponential growth. As the key tech-nology of IoT, Radio-Frequency Identification (RFID) authentication protocol tremendously strengthens pri-vacy protection and improves IoT security. However, it inevitably increases system overhead while improv-ing security, which is a major blow to low-cost RFID tags. The existing RFID authentication protocols are difficult to balance overhead and security. This paper designs an ultra-lightweight encryption function and proposes an RFID authentication scheme based on this function for the end-edge-cloud collaborative environ-ment. The BAN logic proof and protocol verification tools AVISPA formally verify the protocol's security. We use VIVADO to implement the encryption func-tion and tag's overhead on the FPGA platform. Per-formance evaluation indicates that the proposed pro-tocol balances low computing costs and high-security requirements.
