Abstract: With the emergence of Internet of Things (IoT), smart and intelligent applications are being developed. One of the key enabling technologies of IoT is Radio Frequency Identification (RFID). RFID uniquely identifies all connected devices and things in an IoT use case like smart home which may be part of smart city use case in turn. Therefore IoT applications are implicitly made RFID critical. Thus ensuring security and privacy in RFID communications is indispensable for sustainable growth in such applications. With respect to smart home access control, there might be privacy attacks since RFID carries sensitive information of users. Cyber criminals may target to destroy critical digital infrastructure. RFID authentication is made large scale in IoT integrated applications. Therefore, it is essential to have cloud-assisted solution. With cloud integration, RFID authentication reaps benefits of cloud such as scalability, availability and fault tolerance at server side. Nevertheless, cloud is untrusted environment from user point of view and vulnerable to attacks. Therefore there is need for secure and privacy preserving RFID based authentication mechanism. Such system should be able to prevent both internal and external attacks. The mechanisms found in literature are using various schemes to implement security. However, consideration of probability of internal attacks solicits a new model for enhancing security in smart home use case. Towards this end, we proposed a secure and privacy preserving framework to safeguard interests of all stakeholders of the use case as far as security is concerned. The framework is known as RFID based Cloud-assisted Access Control (RCAC). It enables secure communications among parties involved in access control mechanism. It is lightweight, secure, privacy preserving and prevents external and internal attacks. Amazon EC2 is used as cloud platform to evaluate the framework. Experimental results are encouraging and RCAC shows performance improvement over the state of the art.
