Reversing and Fuzzing the Google Titan M Chip
Damiano Melotti, Maxime Rossi-Bellom, Andrea Continella · Reversing and Offensive-Oriented Trends Symposium · 2021
Google recently introduced a secure chip called Titan M in its Pixel smartphones, enabling the implementation of a Trusted Execution Environment (TEE) in Tamper Resistant Hardware. TEEs have been proven effective in reducing the attack surface exposed by smartphones, by protecting specific security-sensitive operations. However, studies have shown that TEE code and execution can also be targeted and exploited by attackers, therefore, studying their security lays the basis of the trust we have in their features.
