Privacy And Security

With the advent of IoT, Device-to-Device (D2D) communications has afforded a new paradigm that reliably facilitates data exchange among devices in proximity without necessarily involving the base (core) network. It is geared towards the need to improve network performance where short-range communications is concerned, as well as supporting proximitybased services. However, the relentless growth in the number of network end-users as well as interconnected communication-capable devices, in the next-generation IoT-based 5G cellular networks has resulted in novel services and applications, most of which are security-sensitive. It is thus of paramount importance that security issues be addressed. A posing challenge is that the devices are mostly resource-constrained in both power and computing. As such, it is not practical to implement present day as well as traditional security frameworks and protocols under such a scenario, unless strides are taken towards the improvements of data throughput rates, higher bandwidth provisioning, lower round trip latencies, enhanced spectral efficiencies, and energy efficiency (leading to even lower power consumption, by the already constrained devices) in IoT 5G/LTE networks. Therefore, this work focused on exploring and designing schemes that enhance security and privacy among communicating parties. Otherwise, without reliable as well as robust privacy and security preservation measures in the network, most services and applications will be exposed to various forms of malicious attacks. With such a widened cyber-attack space, both privacy and security for end users can easily be compromised. The work herein addresses privacy for subscribers to the various available services and applications as well as security of the associated data. Ultimately, we propose a Fog-Cloud computing paradigm-assisted security framework that comprises two schemes. The aim is to implement a lightweight-based cartographic algorithm that ensures that communication overheads, round trip latencies, computational loads as well as energy consumption by the otherwise resource-constrained surveillance cameras deployed remotely, are kept minimal. Overall, by way of both analysis and simulation, we ascertain that a Fog-Cloud computing-based lightweight security-based scheme has the potential to greatly improve security and privacy preservation, as well as overall performance despite the resource-constrained nature of the devices.

Time Latency

The world has experienced a huge advancement in computing technology. People prefer outsourcing their confidential data for storage and processing in cloud computing because of the auspicious services provided by cloud service providers. As promising as this paradigm is, it creates issues, including everything from data security to time latency with data computation and delivery to end-users. In response to these challenges, the fog computing paradigm was proposed as an extension of cloud computing to overcome the time latency and communication overhead and to bring computing and storage resources close to both the ground and the end-users. However, fog computing inherits the same security and privacy challenges encountered by traditional cloud computing. This paper proposed a fine-grained data access control approach by integrating the ciphertext policy attribute-based encryption (CP-ABE) algorithm and blockchain technology to secure end-users’ data security against rogue fog nodes in case a compromised fog node is ousted. In this approach, we proposed federations of fog nodes that share the same attributes, such as services and locations. The fog federation concept minimizes the time latency and communication overhead between fog nodes and cloud servers. Furthermore, the blockchain idea and the CP-ABE algorithm integration allow for fog nodes within the same fog federation to conduct a distributed authorization process. Besides that, to address time latency and communication overhead issues, we equip each fog node with an off-chain database to store the most frequently accessed data files for a particular time, as well as an on-chain access control policies table (on-chain files tracking table) that must be protected from tampering by rogue fog nodes. As a result, the blockchain plays a critical role here because it is tamper-proof by nature. We assess our approach’s efficiency and feasibility by conducting a simulation and analyzing its security and performance.

The cloud computing paradigm is being used because there is no need to setup additional IT infrastructure such as hardware and software, its low up-front cost. Security and privacy of data is important in day to today life especially for applications that uses cloud computing such as social media. Customer information that is stored at Cloud is crucial that needs to be protected against potential intruders. There is threat to maintain the data in transit and data at cloud due to different possible attacks. Due to this there is growing need of privacy and security of data. In this paper, the privacy and issues, privacy preservation techniques are addressed. In addition to this, in order to protect the data, the secret sharing algorithm is implemented and analyzed. The shamir’s secret sharing (k,n) algorithm is used to split the data into n partial shares which can be distributed in cloud. The user collects at least k partial shares to reconstruct the complete data. It is observed that if the file size is increased, the data recovery time is also increased. The paper concludes with privacy preservation guidelines.

AbstractThis article analyzes and highlights the security perspective of Internet of Things (IoT) connected devices and their communication challenges, as IoT is considered one of the key emerging fields in Industry 4.0. The IoT architectures can consist of physical systems, virtual ones or even hybrids, combining a collection of different physically active things, sensors, cloud services, specific IoT protocols, communication layers, users and developers. On top of all, it is the business layer, because the scope of the entire IoT environment is to deliver data, to monitor and to facilitate the management of complex processes. In order to facilitate the data exchange between the IoT layers, there have been developed a series of protocols particular to the IoT domain. As in many IT related fields, the solutions are not perfect from the data security and privacy perspectives, many challenges being still open research issues. As the two concepts of IoT and Cloud of Things are connected, bringing real world data into the Cloud to process it, raises Cloud Computing security concerns regarding the privacy and security of data. Although in recent years, many efforts have been made to improve Cloud Computing security, there are risks that need to be taken into consideration. From the Web of Data’s point of view, things are even more prone to security risks. Because privacy is one of the fundamental right of digital users, it is extremely important for new technologies to comply with privacy regulations and policies, such as the new European data protection and privacy frameworks. In this context, companies must take into account standards, challenges and new trends in IoT. In the absence of specific measures, raw or processed data can be easily stolen from the Web of Data. In this paper we analyze and present the main protocols of communication in the IoT field from a data security perspective. Also, we do a review of the main architectures that can improve the security of the communication between IoT devices and the Cloud data storage.
