An Optimized RFID Unidirectional Authentication Method

Abstract:

To solve the problems of consumers security and privacy, an optimized RFID unidirectional authentication method is proposed, comparing with other asymmetric cryptography, this method has stronger security, shorter key length, less computation and so on. This method achieves one-way authentication between tag and reader-writer, and allow the labels to automatically update the key to improve the performance of RFID authentication, and also can enhance security through updating keys. This method allows the label to update its own name and private key, so can prevent attackers tracking them, so as to solve the privacy problem of the tags.
