A Scalable and Lightweight Grouping Proof Protocol for Internet of Things Applications.

The Internet of Things (IoT) is a new technology, which enables objects to exchange data via the internet network. One part of the infrastructure of IoT is Radio Frequency Identification (RFID). One way to fortify the system and prevent it against an unauthorized access is an authentication process. A grouping proof protocol is a protocol by which a reader authenticates two or more tags simultaneously in an authentication process. In this paper, we present a novel scalable grouping proof protocol. Since scalability is a challenge in grouping proof protocol, to solve the scalability problem in the proposed protocol, the reader broadcasts the messages and the tags respond to it independently. In terms of the performance, we use a 64-bit lightweight Pseudo-Random Number Generator (64-PRNG) function, which meets the needs of low-power and low-cost systems. In addition, the security analysis results prove that the proposed protocol is resistant against RFID threats and provides an acceptable security level and low computation cost. [ABSTRACT FROM AUTHOR]
