Safety for Low-Cost RFID Tags Using Lightweight Authentication Protocol

Abstract

In this article we consider the actual problem of safety for Low-Cost RFID Tags which are used pretty often in an everyday life, for example in shops. Thus the basic complexity consists that Low-Cost RFID Tags are limited in resources and as consequence, cannot support strong cryptography. Therefore for Low-Cost RFID Tags it is expedient to use the special lightweight algorithms and protocols which should be developed taking into account functional limitation of RFID Tags. We produce one of possible authentication protocol which can be applied as the lightweight protocol to use in Low-Cost RFID Tags, and also we will result its comparative analysis with other authentication protocols developed earlier
