SAMA: Serverless Anonymous Mutual Authentication for Low-Cost RFID Tags

An RFID system generally consists of tags, readers, and backend servers with the readers charged with authenticating/identifying the tags with the help of the servers. Two important enhancements have been suggested for widespread adoption of RFIDs, namely the use of low cost (5? or less) passive RFID tags and serverless system design to overcome the need for persistent connection between the readers and the servers. Unfortunately, the low cost tags lack computation and storage capabilities to implement sophisticated security protocols to provide tag privacy and anonymous mutual authentication between the readers and the tags.
