Abstract. RFID (Radio Frequency Identification) has achieved widespread
success in supply chain management, object identification, and assets tracking.
In these applications, we often need to search for a particular set of products
in a large-scale collection of products. Existing schemes have been proposed,
but they are limited by a couple of problems. Firstly, they fail to work under the
situation when the cardinality of X is much larger than that of Y. Secondly, they
implicitly assume the RFID readers are adequate powerful so that readers can
handles a large number of query requests in a short time. To this end, we
propose ITSP -- Cloud-based Iterative Tag Search Protocol, which can locate
the tags in a secure and efficient manner. To be secure, ITSP authenticates the
communications between RFID readers and tags to in advance. To be efficient,
ITSP reformats the single-round communication model to a multi-round
communication one between readers and tags. Furthermore, ITSP employs a
cloud-based service to rapidly conduct the searching process. Extensive
experimental results show that the proposed scheme achieves high-levels of
searching efficiency with the improvement at least 19%.

1 Introduction
RFID (Radio Frequency Identification) is a wireless communication technology [1],
which applies radio signals to identify specific targets without touching objects
mechanically and optically. Usually, An RFID system consists of three parts:
readers, tags, and antennae. The readers transmit encoded radio signal to interrogate
the tags and gets stored information within tags. Readers have relatively powerful
computation and storage capability [11]. Each tag has a unique ID according to the
EPC global Class-1 Gen-2 standard [12]. It receives the reader message and responds
with required information. RFID antenna receives and transmits the radio signal
between tags and readers. Owing to its low cost, non-contact sensing, and
miniaturization, RFID has been widely adopted in inventory management [2], product
tracking, intelligent transportation systems [3-5], animal identification and healthcare
systems [6-8].
