Credential Management Enforcement and Secure Data Storage in gLite

This article describes new security solutions for Grid middleware, and specifically faces the issues related to the management of users’ and servers’ credentials, together with storing and secure data transmission in the Grid. Our work, built on Grid Security Infrastructure (GSI), provides new capabilities (i.e. smart card Grid access, and strong security file storage XML-based) to be used on top of different Grid middlewares, with a low level of changes. This work is currently implemented on gLite and accomplishes the access to Grid resources in a uniform and transparent way. These improvements enable the Grid computing toward the new processing model known as business services.

Hardware Platforms

Tools for archiving and extraction of data in Ukrainian National Grid for end-users’ applications are proposed, implemented and deployed for practical applications in medical imaging, non-linear dynamics, and molecular biology. Proposed tools provide the facilities to utilize large distributed storage space in grid infrastructures for different practical tasks including desktop applications. Tools may be successfully used even when on client platforms it is impossible to setup grid middleware, use web browser interfaces or grid security infrastructure authentication. Tools consist of extensible client compatible with different software and hardware platforms; web service for data transfer; web service for transparent data replication on grid storage elements.

Secure Data

In this paper, a blockchain-based secure data sharing mechanism is proposed for Vehicular Networks (VNs). Edge service providers are introduced along with ordinary nodes to efficiently manage service provisioning. The edge service providers are placed in the neighborhood of the ordinary nodes to ensure smooth communication between them. The huge amount of data generated by smart vehicles is stored in a distributed file storage system, known as Interplanetary File System (IPFS). It is used to tackle the issues related to data storage in centralized architectures, such as data tampering, lack of privacy, vulnerability to hackers, etc. Monetary incentives are given to edge vehicle nodes to motivate them for accurate and timely service provisioning to ordinary nodes. In response, ordinary nodes give reviews to the edge nodes against the services provided by them, which are further stored in a blockchain to ensure integrity, security and transparency. Smart contracts are used to automate the system processes without the inclusion of an intermediate party and to check the reviews given to the edge nodes. To optimize gas consumption and to enhance the system performance, a Proof of Authority (PoA) consensus mechanism is used to validate the transactions. Moreover, a caching system is introduced at the edge nodes to store frequently used services. Furthermore, both security and privacy are enhanced in the proposed system by incorporating a symmetric key cryptographic mechanism. A trust management mechanism is also proposed in this work to calculate the nodes’ reputation values based upon their trust values. These values determine the authenticity of the nodes involved in the network. Eventually, it is concluded from the simulation results that the proposed system is efficient for VNs.
