Trusted Execution Environments, such as Intel SGX, use hardware supports toensure the confidentiality and integrity of applications against a compromisedcloud system. However, side channels like access patterns remain foradversaries to exploit and obtain sensitive information. Common approaches useoblivious programs or primitives, such as ORAM, to make access patternsoblivious to input data, which are challenging to develop. This demonstrationshows a prototype SGX-MR-Prot for efficiently protecting access patterns ofSGX-based data-intensive applications and minimizing developers' efforts.SGX-MR-Prot uses the MapReduce framework to regulate application dataflows toreduce the cost of access-pattern protection and hide the data obliviousdetails from SGX developers. This demonstration will allow users to intuitivelyunderstand the unique contributions of the framework-based protection approachvia interactive exploration and visualization.
