S\u00e9minaire R3S de Sana Belguith, universit\u00e9 d’Auckland, le vendredi 20 avril 2018, \u00e0 14h00 en Salle G10<\/p>\n
Title:<\/strong> Research project STRATUS: Security Technologies Returning Accountability, Trust and User-centric Services in the Cloud<\/p>\n Abstract:<\/strong> From the Apple iCloud celebrity nude photo leaks [1], to the abuse of user\u2019s photographs on social networking services (e.g. Instagram and Facebook) for use of explicit sites [2], to the recent leakage of information belonging to 1 billion user accounts on Yahoo platform [3], we are regularly witnessing a serious problem: the inability for data owners to help themselves in cyber security breaches situations.<\/p>\n STRATUS project is a New Zealand cyber security research project focusing on empowering users with control over their data in third party environments such as the cloud.<\/p>\n First, this talk will present an overview of STRATUS project goals and achievements.<\/p>\n Then, the presentation will focus on the research activities performed by Cyber Security Foundry, The University of Auckland. These research contributions are mainly related to data security and user\u2019s privacy in Distributed Systems such as Cloud Computing, Software Defined Networks, Publish and Subscribe Systems, Content Delivery Network, etc., based on Cryptographic techniques.<\/p>\n Indeed, I will present our applications of Searchable Encryption to hide search, access and size patterns of outsourced data to CDNs and Clouds in order to prevent inference attacks [4,5,6]. In addition, the presentation will introduce our contributions to secure Pub\/Sub systems mainly enhancing subscribers\u2019 privacy [7] and ensuring efficient revocation [8]. Finally, I will give few details about our research in progress to reserve the privacy of access pattern using Intel SGX-assisted solutions [9], to prevent denial of service attacks in Software Defined Networks and to protect intellectual property (IP) from reverse engineering using program obfuscation techniques [10].<\/p>\n [1] CNN Money, Goldman, D., Pagliery, J., Segall, L.
