The fourth and last ASSURED webinar, entitled “ASSURED Cybersecurity and Insider Threats: Blockchain-Empowered Mobile Edge Intelligence for Secure and Sustainable Computing“, was held on Tuesday, July 11th, focusing on the use of Blockchain-based technologies as part of the ASSURED framework. The ASSURED Blockchain Infrastructure is a core component of the framework, since it is responsible for providing highly secure data access, sharing, and storage capabilities in a decentralized manner, as well as fulfilling the security, privacy, and trustworthiness requirements of systems adopting the ASSURED framework.
Three presentations were given by members of the ASSURED consortium, discussing various aspects of the Blockchain-related components and functionalities of ASSURED. First, the motivation behind the use of Blockchain technologies in ASSURED framework was discussed, and the positioning of the Blockchain Infrastructure and related components was presented. Next, an overview of the core design of the ASSURED Blockchain was provided, as well as a technical description of the relevant data management and access control schemes, namely Attribute-Based Encryption (ABE), Attribute-Based Access Control (ABAC), and Dynamic Symmetric Searchable Encryption (DSSE). Afterwards, the ASSURED TPM-based Wallet was presented, which constitutes a significant step forward towards adopting decentralized user-centric identity management based on the concept of Self-Sovereign Identities (SSI), aiming to shift the responsibility of identity management to the devices themselves by providing hardware-based trustworthiness guarantees. Finally, demo presentations of the ASSURED framework were performed on the execution flow of the entire ASSURED framework, including the generation and deployment of the attestation policies to the Blockchain, the execution of the attestation actions specified in these policies by the target device, and the storage of the attestation report on the Blockchain.
The webinar was attended by experts and academics from various application domains, and was part of the ASSURED dissemination activities geared towards sharing the outcomes and innovations of the project, both from a research and an implementation standpoint. This is particularly significant in the case of Blockchain technologies, since they have recently attracted considerable research interest and are used in a wide variety of applications. This webinar was a significant step towards sharing the contributions of ASSURED in this regard, and towards the advancement of the state-of-the-art in research fields related to Blockchain and data sharing methods.
