Secret Sharing-based RFID Authentication Protocol in Smart Hospital

摘要

Privacy preserving is one of the most concern in our daily life, especially in public. So we propose a RFID mutual authentication protocol which is available in the smart hospital to solve these problems. The authentication between the tag and the reader is carried out only after the back-end server has verified the validity of both the tag and the reader. Then the server is able to keep track of the tag together with its owner precisely. With the special secret sharing, all the tags are monitored in our hospital, but a malicious adversary can't trace any tag. Our scheme is not only secure against lots of attacks, but also achieves high efficiency in the identification of these tags.
