In a fog-enabled IoT environment, a fog node is regarded as the proxy between end users and cloud servers to reduce the latency of data transmission, so as to fulfill the requirement of more real-time applications. A data storage scheme utilizing fog computing architecture allows a user to share cloud data with other users via the assistance of fog nodes. In particular, a fog node obtaining a re-encryption key of the data owner is able to convert a cloud ciphertext into the one which is decryptable by another designated user. In such a scheme, a proxy should not learn any information about the plaintext during the transmission and re-encryption processes. In 2020, an ID-based data storage scheme utilizing anonymous key generation in fog computing was proposed by some researchers. Although their protocol is provably secure in a proof model of random oracles, we will point out that there are some security flaws inherited in their protocol. On the basis of their work, we further present an improved variant, which not only eliminates their security weaknesses, but also preserves the functionalities of anonymous key generation and user revocation mechanism. Additionally, under the Decisional Bilinear Diffie–Hellman (DBDH) assumption, we demonstrate that our enhanced construction is also provably secure in the security notion of IND-PrID-CPA.

“…Central Authentication Service (CAS) performs distributed identity and it also presents architecture for distributed identity services in cloud dependent technologies. In federated identity management design, such as OpenID Connect, it does not require registration in cloud for accessing [6]. However, incorporation between identity management and cloud computing is still a trail-particularly with respect to privacy and security issues [7].…”

Emphasis on security for providing Access Control in Cloud computing environment plays a significant role. Cloud computing provides number of benefits such as resource sharing, low speculation and large storage space. Huge amount of information stored in cloud can be accessed from anywhere, anytime on pay-per use basis. Resources in cloud should be accessed only by the authorized clients. Access Control in cloud computing has become a critical issue due to increasing number of users experiencing dynamic changes. Authentication, authorization and approval of the access ensuring liability of entities from login credentials including passwords and biometric scan is essential. Also, the federated authentication management is secured. Current approaches require large-scale distributed access control in cloud environment. Data security and access control are the drawbacks in existing access control schemes. Due to the drawbacks in existing access control schemes such as privacy of information when susceptible information is stored in intermediary service provider a federated identity access management is essential. Access control applications majorly concentrate on Healthcare, Government Organizations, Commercial, Critical Infrastructure and Financial Institutions. This review illustrates a detailed study of access control models in cloud computing and various cloud identity management schemes.

Cloud Computing was a disruptive technology that reshaped the entire global industry, decentralizing the operational exchange and use of data and information. More companies are transitioning to a cloud-based infrastructure and are shifting some basic as well as advanced functionalities to it due to its salient features such as security, availability, scalability and popularity. Nevertheless, there is uncertainty attached to its limitations considering the possible saturation of the ceiling of growth and subsequent maturity of the technology’s potential. Therefore, it is essential to grasp the scope of the technology to be ready for the prospective trends and changes, as well as to channel its full incremental potential. For this, an elucidated statistical analysis of the technology is conducted, including the assessment of the trends of publications and patents signifying the evolution of the technology, its projected time of maturity, and finally, a befitting evidential roadmap for its future. This original work aims to add value by analyzing the numerical information concerning the growth of the technology over the years since its inception, and subsequently construct a detailed plan to adapt business objectives to the possible tapering of the growth curve of Cloud and build a suggestive and tentative contingency plan for the stage of technological maturity. Our finding indicates that Cloud technology may reach its maturity sooner than expected and an investment today might give the companies a competitive edge early on in the era of technological advancements and uncertainty.
