A security evaluation of TrustZone based trusted execution environments
Αξιολόγηση της ασφάλειας των αξιόπιστων περιβάλλοντων εκτέλεσης που βασίζονται στη τεχνολογία Trustzone
Trusted execution environments are marketed as a secure and robust solution that can greatly enhance the overall security of the system it is installed on. In this work we aim to analyze the architecture of trusted execution environment as a concept while also seeing in detail the implementation aspects of the TrustZone based trusted execution environments. Furthermore we aim to evaluate the actual security provided by this solution through an exploration of the characteristics of the various attacks and vulnerabilities that have been recorded in the bibliography.
