Abstract: RFID grouping proof protocol, which was the instantiation of the RFID application, needs higher secure and lightweight requirement. According to the participation of the verifier in the protocol, online and offline verifier tree-based lightweight RFID group proof protocol OTLP and FTLP separately were put forward. Both protocols can meet the RFID group proof protocol’s security requirements. Compared with the existing group proof protocol, they require less computational complexity and have higher efficiency and availability.

Key words: RFID grouping proof protocol; tree-based model; lightweight
