Dialectal Execution Environment

Abstract

Despite the various software-based defense techniques being proposed and applied, the computing environment is still unsafe from numerous software attacks. Advances in the computing performance of embedded devices have enabled the implementation of a variety of services for the convenience of users while changing the daily lives of people in a variety of ways compared to the past. ARM TrustZone is one of the most widely deployed security architecture providing Trusted Execution Environments Unfortunately, its usage and potential benefits for third-party developers are largely limited due to restricted deployment policies imposed by device vendors. We propose Dialectal Execution Environment to ameliorate this problem. Dialectal Execution Environment builds the Trusted Execution Environment that allows only authorized users to understand the binary and run the binary correctly.
