Mobile App to SGX Enclave Secure Channel
2019
The current challenge for several applications is to guarantee the user's privacy when using personal data. The broader problem is to transfer and process the data without exposing the sensitive content to anyone, including the service provider(s). In this paper, we address this challenge by proposing a protocol to combine secure frameworks in order to exchange and process sensitive data, i.e. respecting user's privacy. Our contribution is a protocol to perform a secure exchange of data between a mobile application and a trusted execution environment. In our experiments we show independent implementations of our protocol using three different encryption modes (i.e., CBC, ECB, GCM encryption). Our results support the feasibility and importance of an end-to-end secure channel protocol.
