Method of Secret Splitting: Novel Way to Authenticate Rfid Tags and Reader

A globally accepted, auto-identification technology, became popular in the post World War II period – the RFID technology works without any contact between the participating entities. As an auto-identification technology, RFID has overcome the demerits of barcodes. RFID find its applications in pharmaceuticals, animal tracking, and inventory control to name a few. However, inspite of its huge area of applications, deploying RFID technology has become a great challenge for the organizations. In many cases, either the reader is not properly authenticated or tags are not authenticated, due to which malicious tags easily communicate with the reader. Hence, in this article, we propose to extend the scheme of “secret splitting” which involves the reader, tag and also the back-end server in the process of authentication, thus eliminating the threat of replay attack.
