Abstract

This work presents Computer Security by Hardware-Intrinsic Authentication (CSHIA), a secure computer architecture for embedded systems that aims at providing authenticity and integrity for code and data. The work encompassed three phases: Design, Implementation, and Security Evaluation. In design, we laid out the basic ideas behind CSHIA, namely, how integrity and authenticity are employed through the use of Physical Unclonable Functions (PUFs), and we proposed an algorithm to extract cryptographic keys from the intrinsic memories of processors. In implementation, we made CSHIA¿s design more flexible, allowing different configurations without compromising security. Then, we evaluated CSHIA¿s performance and overheads, such as area, energy, and memory, for multiple configurations. Finally, we evaluated security of PUFs, which led us to develop a new side-channel-based attack that enabled us to circumvent PUFs¿ uniqueness property through their architectural elements (AU)
