As a response to a growing interest in RFID systems such as Internet of Things technology along with satisfying the security of these networks, proposing secure authentication protocols are indispensable part of the system design. Hence, authentication protocols to increase security and privacy in RFID applications have gained much attention in the literature. In this study, security and privac...

advanced metering infrastructure (ami) is a key part of the smart grid; thus, one of the most important concerns is to offer a secure mutual authentication.  this study focuses on communication between a smart meter and a server on the utility side. hence, a mutual authentication mechanism in ami is presented based on the elliptic curve cryptography (ecc) and one time signature (ots) consists o...

Nowadays Radio Frequency Identification (RFID) systems have appeared in lots of identification and authentication applications. In some sensitive applications, providing secure and confidential communication is very important for end-users. To this aim, different RFID authentication protocols have been proposed, which have tried to provide security and privacy of RFID users. In this paper, we a...

The wireless communication with delivering variety of services to users is growing rapidly in recent years. The third generation of cellular networks (3G), and local wireless networks (WLAN) are the two widely used technologies in wireless networks. 3G networks have the capability of covering a vast area; while, WLAN networks provide higher transmission rates with less coverage. Since the two n...
