SECURING USER INTERACTION CHANNELS ON MOBILE PLATFORM USING ARM TRUSTZONE
… commonly deployed TEE on mobile devices being ARM TrustZone.</p> <p>This dissertation utilizes ARM TrustZone to provide secure design for user interactionchannels of UI input (called Truz-UI) and Audio I/O for VoIP calls (called Truz-Call). The primary goal is to ensure that the design is …

Extending secure and trusted computation to FPGA accelerators
… trusted computing solutions such as Intel SGX or ARM TrustZone target at CPU-only environments, making external accelerators and peripheral devices unprotected. This work proposes a new scheme to extend trust computing for FPGA accelerators. The scheme consists of a security manager (SM) with …

TRUSTED RUNTIME ENVIRONMENTS FOR EMBEDDED SYSTEMS: FROM MEMORY PROTECTION TO SECURE VIRTUALIZATION
… a secure virtualization framework that extends ARM-based TEEs to multi-tenant cloud environments. VS-TEE enables multiple virtual machines to securely share TEE resources, overcoming the limitations of current hardware-backed confidential computing solutions. It integrates hypervisor-level …

Improving Digital Forensics and Incident Analysis in Production Environments by Using Virtual Machine Introspection
… access. We discuss how cold boot attacks, the ARM TrustZone and the hypervisor of cloud servers can be used to acquire data from storage. The third challenge is how to reconstruct information from main memory efficiently. This thesis describes how these questions can be solved by employing two …

Hardening Trusted Execution Environments Against Microarchitectural Side-Channel Attacks: A Constructive Approach
… TEE platforms including Intel SGX, AMD-SEV, and ARM TrustZone. Existing approaches to defend against these attacks face significant limitations. Hardware-based solutions [12–14] often require complex processor modifications with significant hardware overhead. Replacing trusted hardware with …

The Art of SRAM Security: Tactics for Remanence-based Attack and Strategies for Defense
… security solutions in the ongoing "security arms race". I present an attack, volt boot, that executes cold-boot style short-term data remanence in on-chip SRAM without using temperature effect. This attack exploits the fact that SRAM's power bus is externally accessible and allows data …

Handling mixed-criticality systems on low-end and low-power IoT devices
… as crescentes preocupações de segurança, a Arm introduziu a tecnologia TrustZone nas suas arquiteturas Cortex-M (Armv8-M). Em processadores de alto desempenho, o TrustZone tem sido o principal impulsionador na implementação de Trusted Execution Environments (TEEs). Os TEEs providenciam …
