Separation Model

Abstract Separation is the primary consideration in cloud computing security. A series of security and safety problems would arise if a separation mechanism is not deployed appropriately, thus affecting the confidence of cloud end-users. In this paper, together with characteristics of cloud computing, the separation issue in cloud computing has been analyzed from the perspective of information flow. The process of information flow in cloud computing systems is formalized to propose corresponding separation rules. These rules have been verified in this paper and it is shown that the rules conform to non-interference security, thus ensuring the security and practicability of the proposed rules.

Abstract –Today Security issue is the topmost problem in the cloud computing environment. It leads to serious discomfort to the Governance and end-users. Numerous security solutions and policies are available however practically ineffective in use. Most of the security solutions are centered towards cloud technology and cloud service providers only and no consideration has been given to the Network, accessing, and device securities at the end-user level. The discomfort at the end-user level was left untreated. The security of the various public, private networks, variety of devices used by end-users, accessibility, and capacity of end-users is left untreated. This leads towards the strong need for the possible modification of the security architecture for data security at all levels and secured service delivery. This leads towards the strong need for the possible adaption of modified security measures and provisions, which shall provide secured hosting and service delivery at all levels and reduce the security gap between the cloud service providers and end-users. This paper investigates the study and analyze the security architecture in the Cloud environment of Govt. of India and suggest the modifications in the security architecture as per the changing scenario and to fulfill the future needs for the secured service delivery from central up to the end-user level.

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.

Fog computing is a new paradigm believed to be an extension of cloud computing and services to the sting of the network. Similarly, like Cloud, Fog provides computing, data, storage, and various application services to the connected end-users. Fog computing uses one or a lot of combined end users or nearby end users edge devices to perform the configuration, communication, storage, control activity, and management functions over the infrastructure supported. This new paradigm solves the latency and information measure limitation issues encountered from the cloud computing. Primarily, the architecture of the fog computing is discussed and analyzed during this work and then indicates the connected potential security and trust problems. Then, however such problems are tackled within the existing literature is systematically reportable. Finally, the open challenges, analysis, trends, and future topics of security and trust in fog computing are mentioned.

High Scalability

Pushing computing, control, data storage, and processing into the cloud has been a key trend in the past decade. However, the cloud alone encounters growing limitations, such as reduced latency, high mobility, high scalability, and real-time execution in order to meet the upcoming computing and intelligent networking demands. A new paradigm called fog computing has emerged to overcome these limits. Fog extends cloud computing and services to the edge of the network. It provides data, computing, storage, and application services to end-users that can be hosted at the network edge. It reduces service latency, and improves QoS/QoE, that results in superior user experience. This chapter is about introduction and overview of fog computing, comparison between fog computing and cloud computing, fog computing and mobile edge computing, possible fog computing architecture, applications of fog computing, and possible research directions.

Access To Data

Cloud computing has been heralded as a new era in the evolution of information and communications technologies. ICT giants have invested heavily in developing technologies and mega server facilities, which allow end users to access web-based software applications and store their data off-site. Businesses using cloud computing services will benefit from reduced operating costs as they cut back on ICT infrastructure and personnel. Individuals will no longer need to buy and install software and will have universal access to their data through any internet-ready device. Yet, hidden amongst the host of benefits are inherent legal risks. The global nature of cloud computing raises questions about privacy, security, confidentiality and access to data. Current terms of use do not adequately address the multitude of legal issues unique to cloud computing. In the face of this legal uncertainty, end users should be educated about the risks involved in entering the cloud.

This paper describes an empirical investigation of the usability of different dialogue designs for voiceprint authentication in automated telephone banking. Three strategies for voice authentication were evaluated in an experiment with 120 telephone banking end-users: 1-Factor (voiceprint authentication based on customers' utterances of their account number and sort code); 1-Factor with Challenge (1-Factor plus a randomly generated digit string); and 2-Factor (1-Factor plus secret information known only to the caller). The research suggests the 2-Factor approach is the most effective strategy in this context: results from a Likert questionnaire show it to be highly usable and it is rated highest in terms of both security and overall quality. Participants welcome the option to use voiceprint technology but the majority would prefer it to augment rather than replace existing security methods.
