Access control is a critical aspect for improving the privacy and security of IoT systems. A consortium is a public or private association or a group of two or more institutes, businesses, and companies that collaborate to achieve common goals or form a resource pool to enable the sharing economy aspect. However, most access control methods are based on centralized solutions, which may lead to problems like data leakage and single-point failure. Blockchain technology has its intrinsic feature of distribution, which can be used to tackle the centralized problem of traditional access control schemes. Nevertheless, blockchain itself comes with certain limitations like the lack of scalability and poor performance. To bridge the gap of these problems, here we present a decentralized capability-based access control architecture designed for IoT consortium networks named IoT-CCAC. A blockchain-based database is utilized in our solution for better performance since it exhibits favorable features of both blockchain and conventional databases. The performance of IoT-CCAC is evaluated to demonstrate the superiority of our proposed architecture. IoT-CCAC is a secure, salable, effective solution that meets the enterprise and business’s needs and adaptable for different IoT interoperability scenarios.

Cloud computing enables users to accumulate their sensitive data into cloud service providers to achieve scalable services on-demand. Outstanding security requirements arising from this means of data storage and management include data security and privacy. Attribute-based Encryption (ABE) is an efficient encryption system with fine-grained access control for encrypting out-sourced data in cloud computing. Since data outsourcing systems require flexible access control approach Problems arises when sharing confidential corporate data in cloud computing. User-Identity needs to be managed globally and access policies can be defined by several authorities. Data is dual encrypted for more security and to maintain De-Centralization in Multi-Authority environment.

IoT is a network of interconnected heterogeneous devices which sense, accumulate the data and forward the same to the cloud platform for analytical purposes. There are various IoT verticals in which huge research is going on. IoT security is the most challenging research area in which researchers are investing a huge number of efforts. The challenges in IoT security include access control, trust management, authentication, authorization, privacy, and secured device to device communication. To overcome these, this paper gives an overview of proposed trust based distributed access control approach in IoT. Some of the challenges and threats can be controlled by blockchain technology. Basically, blockchain is an open and distributed ledger of records that can be verified efficiently and stored permanently. This paper checks the feasibility study of the applicability of blockchain in the IoT ecosystem to apply access control mechanism and privacy-preserving policies. This paper discusses how access control and privacy can be addressed by blockchain without compromising security. This paper consists of rigorous gap analysis which is done on the top of comprehensive literature survey. The paper also addresses the challenges and issues which can be faced while applying access control mechanism using blockchain in the context of IoT.

Purpose Pervasive computing environment allows the users to access the services anywhere and anytime. Due to the dynamicity, mobility, security, heterogeneity, and openness have become a major challenging task in the Pervasive computing environment. To solve the security issues and to increase the communication reliability, an authentication-based access control approach is developed in this research to ensure the level of security in the Pervasive computing environment. Design/methodology/approach This paper aims to propose authentication-based access control approach performs the authentication mechanism using the hashing, encryption, and decryption function. The proposed approach effectively achieves the conditional traceability of user credentials to enhance security. Moreover, the performance of the proposed authentication-based access control approach is estimated using the experimental analysis, and performance improvement is proved using the evaluation metrics. It inherent the tradeoff between authentication and access control in the Pervasive computing environment. Here, the service provider requires authorization and authentication for the provision of service, whereas the end-users require unlinkability and untraceability for data transactions. Findings The proposed authentication-based access control obtained 0.76, 22.836 GB, and 3.35 sec for detection rate, memory, and time by considering password attack, and 22.772GB and 4.51 sec for memory and time by considering without attack scenario. Originality/value The communication between the user and the service provider is progressed using the user public key in such a way that the private key of the user can be generated through the encryption function.
