Obelix: Mitigating Side-Channels through Dynamic Obfuscation

Trusted execution environments TEEs offer hardware-assisted means to protect code and data. However, as shown in numerous results over the years, attackers can use side-channels to leak data access patterns and even single-step the code. While the vendors are slowly introducing hardware-based...
