Trusted Execution Environments (TEEs), initially developed for cloud computing, create secure processor areas to protect sensitive data. However, TEEs are not yet integrated into emerging platforms due to their recency and ongoing development. Despite this, increasing security expectations and new privacy regulations necessitate adapting TEEs for these platforms. This thesis focuses on hardening and adapting TEEs for emerging platforms, particularly Virtual Reality (VR).\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003ETo harden existing TEEs,\u0026nbsp;\u003C\/em\u003Ethis thesis presents SENSE, an architectural extension that allows TEE programs to subscribe to fine-grained microarchitectural events, thus improving the microarchitectural awareness of TEEs and enabling proactive defenses previously unfeasible. \u003Cem\u003ETo understand VR security,\u0026nbsp;\u003C\/em\u003Ethis thesis introduces MIRAGE, a black-box fuzzing framework for commercial VR applications. MIRAGE features a virtual device driver that replicates VR devices for accurate session replays without hardware. It mutates VR inputs to simulate user interactions and evaluates quality of experience (QoE), detecting abnormalities. \u003Cem\u003ETo enable TEEs on emerging platforms,\u0026nbsp;\u003C\/em\u003Ethis thesis finally presents PORTAL, a secure and efficient device I\/O interface for Arm Confidential Compute Architecture (CCA) on modern mobile Arm processors, facilitating practical adoption on VR platforms. PORTAL addresses challenges due to memory encryption in the architectural trend of an increasing number of integrated devices within Arm processors. By leveraging Arm CCA\u2019s memory isolation mechanism, PORTAL enforces hardware-level access control without memory encryption. PORTAL offers robust security guarantees while eliminating the overhead of memory encryption, maintaining the QoE crucial for interactive mobile platforms such as VR.\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EHardening and Adapting Trusted Execution Environments for Emerging Platforms\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Hardening and Adapting Trusted Execution Environments for Emerging Platforms"}],"uid":"27707","created_gmt":"2024-07-09 15:47:07","changed_gmt":"2024-07-09 15:51:46","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2024-07-22T10:00:00-04:00","event_time_end":"2024-07-22T12:00:27-04:00","event_time_end_last":"2024-07-22T12:00:27-04:00","gmt_time_start":"2024-07-22 14:00:00","gmt_time_end":"2024-07-22 16:00:27","gmt_time_end_last":"2024-07-22 16:00:27","rrule":null,"timezone":"America\/New_York"},"location":"CODA C0915 \/ Zoom","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
