Secure CXL protocol for cloud application

• According to the most recent white papers, CXL is not sufficiently prepared for secure inter-device communication 

• Currently working on identifying potential performance problems in the setup and alleviating the problems in a simulator 

• Leading this ongoing project 

TEE technology for serverless computing

• Serverless applications consist of multiple functions provided by mutually distrustful parties.

• Proposed an extended TEE model which supports trusted serverless applications hardened by hardware.

• Participated as the first author leading the project.

Supporting Multi-level security in TEE

• Monolithic design of intel SGX is hard to represent complex software structure securely. 

• Designed and emulate new instructions in SGX SDK/Driver to provide fine-grained hierarchical isolation within TEE 

• Participated as the first author leading the project

• Published in ISCA 2020.

Secure key-value storage with Intel SGX

• Limited enclave protected memory significantly slows down in-memory key-value store 

• Proposed a secure key-value store that has a hash-based index structure and provides fine-grained data protection 

• Participated as the second author to discuss the idea, implement the key-value store, and motivational experiments.

• Published in SoCC 2018 as a poster and published in EuroSys 2019.
