Abstract
The Cloud of Things (IoT) that refers to the integration of the Cloud Computing (CC) and the Internet of Things (IoT), has dramatically changed the way treatments are done in the ubiquitous computing world. This integration has become imperative because the important amount of data generated by IoT devices needs the CC as a storage and processing infrastructure. Unfortunately, security issues in CoT remain more critical since users and IoT devices continue to share computing as well as networking resources remotely. Moreover, preserving data privacy in such an environment is also a critical concern. Therefore, the CoT is continuously growing up security and privacy issues. This paper focused on security and privacy considerations by analyzing some potential challenges and risks that need to be resolved. To achieve that, the CoT architecture and existing applications have been investigated. Furthermore, a number of security as well as privacy concerns and issues as well as open challenges, are discussed in this work.
Highlights
The world is undergoing major changes or technological developments with the advent of computer “things”, first on the Internet and in Cloud Computing (CC)
The considered smart devices are capable in collecting, storing, transferring and processing data from the environment, without discontinuity between the virtual and the physical worlds [1,2,3]. This is known as the Internet of Things (IoT), which has been defined by the International Telecommunication Union (ITU) as a network that enables connectivity in any place and any time for any connected whatever devices
The Concept of Cloud of Things (CoT) which is from the combination of modern cloud technology and IoT represents a big leap ahead in the future Internet
Summary
The world is undergoing major changes or technological developments with the advent of computer “things”, first on the Internet and in Cloud Computing (CC). Computer networks are no longer isolated, they are opening up to the great world of Internet, which connects computers and a number of smart and miniaturized objects of our daily life such as embedded electronic chips, sensors, actuators, and smart software, for providing pervasive information access. A new computing paradigm in which the CC functionalities and IoT act as two merged linked technologies is expected in order to disrupt the actual and the future Internet Once these two technologies, i.e., IoT and CC are put together, the resulting technology called CloudIoT or Cloud of Things (CoT) become the post CC era [13,21], which enabled new perspectives including Big Data collection and processing [10,22] as well as resource constraints, scalability, security and privacy concerns [23,24].
