Abstract:

Nowadays, there is an increasing number of concerns about how to ensure both usability and security of data. In this paper, we propose a trusted execution environment (TEE) based confidential computing architecture to protect the data privacy without affecting its usability. We first abstract a model for the scenarios that privacy-preserving computing applies, then design a TEE-based confidential computing architecture and analysis its security.

Key words: trusted execution environment, confidential computing, privacy preserving computation
