Fog Computing: A Taxonomy, Survey and Future Directions
In recent years, the number of Internet of Things (IoT) devices/sensors has
increased to a great extent. To support the computational demand of real-time
latency-sensitive applications of largely geo-distributed IoT devices/sensors,
a new computing paradigm named "Fog computing" has been introduced. Generally,
Fog computing resides closer to the IoT devices/sensors and extends the
Cloud-based computing, storage and networking facilities. In this chapter, we
comprehensively analyse the challenges in Fogs acting as an intermediate layer
between IoT devices/ sensors and Cloud datacentres and review the current
developments in this field. We present a taxonomy of Fog computing according to
the identified challenges and its key features.We also map the existing works
to the taxonomy in order to identify current research gaps in the area of Fog
computing. Moreover, based on the observations, we propose future directions
for research
I2PA : An Efficient ABC for IoT
Internet of Things (IoT) is very attractive because of its promises. However,
it brings many challenges, mainly issues about privacy preserving and
lightweight cryptography. Many schemes have been designed so far but none of
them simultaneously takes into account these aspects. In this paper, we propose
an efficient ABC scheme for IoT devices. We use ECC without pairing, blind
signing and zero knowledge proof. Our scheme supports block signing, selective
disclosure and randomization. It provides data minimization and transactions'
unlinkability. Our construction is efficient since smaller key size can be used
and computing time can be reduced. As a result, it is a suitable solution for
IoT devices characterized by three major constraints namely low energy power,
small storage capacity and low computing power
Securing Our Future Homes: Smart Home Security Issues and Solutions
The Internet of Things, commonly known as IoT, is a new technology transforming businesses, individuals’ daily lives and the operation of entire countries. With more and more devices becoming equipped with IoT technology, smart homes are becoming increasingly popular. The components that make up a smart home are at risk for different types of attacks; therefore, security engineers are developing solutions to current problems and are predicting future types of attacks. This paper will analyze IoT smart home components, explain current security risks, and suggest possible solutions. According to “What is a Smart Home” (n.d.), a smart home is a home that always operates in consideration of security, energy, efficiency and convenience, whether anyone is home or not
