Software-defined networking (SDN) is a programmable architecture for networking domain in which the security is provided by devising the network policies with the help of the network administrator. This is very cumbersome for the administrator to handle different attacks at various planes in SDN architecture. Blockchain can be used to prevent various attacks in SDN by providing a decentralization authentication environment. In this article, a secure Blockchain-based privacy-preserving protocol is proposed to thwart various security vulnerabilities in the SDN architecture. The proposed approach uses Modified-Delegated Proof of Stake as the consensus protocol to ensure safety and reliability in the network. Besides, a security protocol is designed using cryptographic primitives and analyzed using a detailed security analysis. Initially, the consensus protocols are implemented using solidity smart contracts and deployed to the public Blockchain using Ethereum. Consequently, the proposed approach is simulated on OMNet++ using INET framework. The experimental results show that the proposed SDN-Chain is secure, efficient, less incentive to centralize, and practically implementable in resource-limited wireless and mobile environments.

Nowadays, cloud computing is one of the important and rapidly growing paradigms that extend its capabilities and applications in various areas of life. The cloud computing system challenges many security issues, such as scalability, integrity, confidentiality, and unauthorized access, etc. An illegitimate intruder may gain access to the sensitive cloud computing system and use the data for inappropriate purposes that 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 HUDU aims to restrict illegitimate users from accessing the cloud and data security provision. The proposed HUDH consists of three steps: data encryption, data access, and intrusion detection. HUDH 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 Python and Java language. Testing results demonstrate that the HUDH can delegate computation overhead to powerful cloud servers. User confidentiality, access privilege, and user secret key accountability can be attained with more than 97% high accuracy.

With the advancement in digital forensics, digital forensics has been evolved in Cloud computing. A common process of digital forensics mainly includes five steps: defining problem scenario, collection of the related data, investigation of the crime scenes, analysis of evidences and case documentation. The conduction of digital forensics in cloud results in several challenges, security, and privacy issues. In this paper, several digital forensics approaches in the context of IoT and cloud have been presented. The review focused on zone-based approach for IoT digital forensics where the forensics process is divided into three zones. Digital forensics in cloud provides the facilities of large data storage, computational capabilities and identification of criminal activities required for investigating forensics. We have presented a brief study on several issues and challenges raised in each phase of Cloud forensics process. The solution approaches as well as advancement prospects of cloud forensics have been described in the light of Blockchain technology. These studies will broaden the way to new researchers for better understanding and devising new ideas for combating the challenges.
