As the Internet of Things (IoT) has become prevalent, a massive number of logs produced by IoT devices are transmitted and processed every day. The logs should contain important contents and private information. Moreover, these logs may be used as evidences for forensic investigations when cyber security incidents occur. However, evidence legality and internal security issues in existing works were not properly addressed. This paper proposes an autonomous log storage management protocol with blockchain mechanism and access control for the IoT. Autonomous model allows sensors to encrypt their logs before sending it to gateway and server, so that the logs are not revealed to the public during communication process. Along with blockchain, we introduce the concept “signature chain”. The integration of blockchain and signature chain provides efficient management functions with valuable security properties for the logs, including robust identity verification, data integrity, non-repudiation, data tamper resistance, and the legality. Our work also employs attribute-based encryption to achieve fine-grained access control and data confidentiality. The results of security analysis using AVSIPA toolset, GNY logic and semantic proof indicate that the proposed protocol meets various security requirements. Providing good performance with elliptic curve small key size, short BLS signature, efficient signcryption method, and single sign-on solution, our work is suitable for the IoT.

The Internet of Things is taking hold in our everyday life. Regrettably, the security of IoT devices is often being overlooked. Among the vast array of security issues plaguing the emerging IoT, we decide to focus on access control, as privacy, trust, and other security properties cannot be achieved without controlled access. This article classifies IoT access control solutions from the literature according to their architecture (e.g., centralized, hierarchical, federated, distributed) and examines the suitability of each one for access control purposes. Our analysis concludes that important properties such as auditability and revocation are missing from many proposals while hierarchical and federated architectures are neglected by the community. Finally, we provide an architecture-based taxonomy and future research directions: a focus on hybrid architectures, usability, flexibility, privacy, and revocation schemes in serverless authorization.

With the Internet services increased explosively, the requirement for network bandwidth is rigorous. Upon the extraordinary development of process capability, Memory access control has become a key factor that impacts the performance of network processor. The paper proposed a storage management for fast packet buffers in network processor, which can enhance the utilization of bandwidth. Experiment results shows that this approach improved the rates of accessing to memory system in network processor remarkably.

Due to the ever increasing number of web services available through the Internet, the privacy as a fundamental human right is endangered. Informed consent and collection of information are two important aspects while interacting on the Internet through web services. The ease of data access and the ready availability of it through Internet, made it easier for interested parties to intrude into the individual's privacy in unprecedented ways. The regulatory and technical solutions adopted to curb this have achieved only a limited success. The main culprits in this regard are the incompatibilities in the regulatory measures and standards. This research work focuses on privacy preserving access control for sharing sensitive information in the arena of web services, provides some recent outlooks towards the critical need of privacy aware access control technologies and a comprehensive review of the existing work in this arena. Besides, a novel framework for privacy aware access to web services is also provided.
