Distributed Access Control and Authorization (DACA) for Internet of Things

Abstract

In the 21st century, devices surrounding us are
increasing at faster rate and these devices are providing
contextual and adaptive services to all the stake holders. This
paradigm of communication computing which is distributed in
nature is referred as Internet of Things (IoT). Equally, time is
also the crucial factor for any business use cases. To run a
successful business the resource and time need to be
efficiently managed. Now the atomization in all the fields of
engineering helps to save time as well as money. IoT
communication helps to reduce time but now we reach one
step ahead of this traditional communication. This IoT needs
to be intelligent and can be viewed as an intelligent device to
device communication network in which devices are
connected via the Internet. Security in IoT in terms of access
control and authorization is very important. Controlling access
to information is usually done by defining access control
model, which decides who is allowed and who is not. In the
sequel, this paper presents proposed Distributed Access
Control and Authorization (DACA) model for IoT. This paper
also gives idea about challenges and issues faced for
implementation of DACA. Relational calculus based
mathematical model for DACA is also presented and
discussed in the next part of this paper. Implementation of
DACA shows that the local device access time and remote
device access time requires nearly same amount of time which
significant contribution of this paper. This finding proves that
the proposed DACA model is most suited for the IoT.
