In view of the existing defects of RFID authentication protocol

based on the Hash function

and the low efficiency of the security protocol authentication in the application of the Internet of Things

it proposed an improved RFID security mutual authentication protocol

based on the Hash function. This protocol can protect data privacy

and prevent replay attack

privacy track

and spoofing attack. Compared with other protocols of this kind in security and performance

this protocol

which uses Label certification mark Tuse

Tstore and dynamic secret value S

can prevent desynchronization attack

has higher efficiency

and is suitable for low-cost RFID systems.
