A tag determines a handle and a first parameter, both of which may be random numbers, and sends the handle to a reader. Upon receiving a challenge from the reader, the tag determines and sends a cryptographic response to the challenge based on an algorithm, a tag key, the first parameter, and the challenge. Upon receiving a message with a second parameter and a tag instruction, the tag executes the tag instruction upon verifying that the second parameter derives from the first parameter and the tag handle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Tag-handle-based authentication of RFID readers","description":"An RFID tag may execute instructions from an authenticated RFID reader.
