SecTube: SGX-Based Trusted Transmission System.

Trusted communication is a key component in trusted computing paradigm. Sensitive data usually has to be migrated between two applications or platforms in the environment of open network. In this case, not only file integrity monitor tools but also trusted transmission is needed. However, existing trusted transmission solutions run on the user's application platform or operating system. The lack of the isolation makes such security software easy to be subverted. In this paper, we present a novel approach called SecTube to protect the data safety in transmission. It utilizes Intel's new security technology SGX to give user application a safer execution environment. We also present the design and implementation of enclave socket in this paper. We realize the SecTube in Ubuntu 14.04 and several experiments are conducted. The experimental results show the effectiveness of SecTube and demonstrate that the average performance overhead of SecTube is only about 15%.
