“…The vehicle nodes were grouped optimally using the LEACH technique, and the optimum dependability network analysis was The System Lifetime for quite a number of motor vehicles is depicted in figure 5. In comparison to AES, RSA and Hybrid [22], it shows that enhanced RSA algorithm with hashing algorithm performed best. Figures 6 and 7 depict the ideal ERSA-hash algorithm output (proposed).…”

VANET is an emerging platform that enables the inter-communication between the vehicles on-road to exchange control and data messages which can be used to take decisive actions to improve user applications such as congestion and traffic monitoring, secure messaging, and general-purpose Internet connectivity. It does not have a fixed infrastructure and uses wireless, multi-hop communication channels with nodes. The main bottlenecks in implementing a rigid security protocol in VANET applications are the absence of coordinated transmission and the fixed network topology in the VANET. The wireless medium requires various safety applications for the passengers. The availability of the pervasive computing infrastructure paves various paths for security vulnerability. Data security is a concern not only in the vehicular network but also in almost all networked systems, especially wireless networks. The network is vulnerable to compromising key pointers in the system such as confidentiality, integrity, authenticity, and privacy (CIAP). Compromising the CIAP parameters will provide access to any level of control over the network. The paper introduced a secure robust framework to establish the network and enable data communication in VANET using an enhanced RSA algorithm for ESM (Enhanced Security Module) model. The optimized LEACH cluster-based routing algorithm is also used to reduce energy consumption as well as to enhance the security of the data.

“…Cryptography based access control and data a security in cloud have been under constant research. [21] Proposed a new steganography-based access control model that used Improved Key generation scheme of RSA for encrypting data over cloud and substring indexing and keyword search mechanism for extracting the encrypted stored data. The research compared its proposed method with the proposed method and compare with existing cryptographic methods over New York State Department of Health dataset [21].…”

Cloud computing belongs to a set of policies, protocols, technologies through which one can access shared resources such as storage, applications, networks, and services at relatively low cost. Despite the tremendous advantages of cloud computing, one big threat which must be taken care of is data security in the cloud. There are a dozen of threats that we are being exposed to while availing cloud services. Insufficient identity and access management, insecure interfaces and Applications interfaces (APIs), hijacking, advanced persistent threats, data threats, and many more are certain security issues with the cloud platform. APIs and service providers face a huge challenge to ensure the security and integrity of both network and data. To overcome these challenges access control mechanisms are employed. Traditional access control mechanisms fail to monitor the user operations on the cloud platform and are prone to attacks like IP spoofing and other attacks that impact the integrity of the data. For ensuring data integrity on cloud platforms, access control mechanisms should go beyond authentication, identification, and authorization. Thus, in this work, a trust-based access control mechanism is proposed that analyzes the data of the user behavior, network behavior, demand behavior, and security behavior for computing trust value before granting user access. The method that computes the final trust value makes use of the fuzzy logic algorithm. The trust value-based policies are defined for the access control mechanism and based on the trust value outcome the access control is granted or denied.

“…It provides critical services such as restricting unauthorized access, maintaining data integrity, and ensuring data availability. To ensure cloud security, security challenges must be addressed to take full advantage of this computing paradigm [35]. To deeply analyze the origins of unauthorized access in cloud computing systems regarding causation, we followed a proper research methodology.…”

Big Data Handling Approach for Unauthorized Cloud Computing Access

Nowadays, cloud computing is one of the important and rapidly growing services; its capabilities and applications have been extended to various areas of life. Cloud computing systems face many security issues, such as scalability, integrity, confidentiality, unauthorized access, etc. An illegitimate intruder may gain access to a sensitive cloud computing system and use the data for inappropriate purposes, which may lead to losses in business or system damage. This paper proposes a hybrid unauthorized data handling (HUDH) scheme for big data in cloud computing. The HUDH scheme aims to restrict illegitimate users from accessing the cloud and to provide data security provisions. The proposed HUDH consists of three steps: data encryption, data access, and intrusion detection. The HUDH scheme involves three algorithms: advanced encryption standards (AES) for encryption, attribute-based access control (ABAC) for data access control, and hybrid intrusion detection (HID) for unauthorized access detection. The proposed scheme is implemented using the Python and Java languages. The testing results demonstrated that the HUDH scheme can delegate computation overhead to powerful cloud servers. User confidentiality, access privilege, and user secret key accountability can be attained with more than 97% accuracy.
