报告内容简介：

Driven by lower cost, higher reliability, better performance, and faster deployment, data and computing services have been increasingly outsourced to clouds such as Amazon EC2. However, privacy has been the key road block to cloud computing. On one hand, to leverage the computing and storage capability offered by clouds, we need to store data on clouds. On the other hand, due to many reasons, we may not fully trust the clouds for data privacy. In this talk, I will present our work on high-speed query processing with strong privacy protection for cloud computing. We aim to achieve both provable security and computational efficiency for both range queries and keywork queries. For security, we aim to satisfy the strongest security model of adaptive security. For efficiency, we aim to achieve a query processing speed of a few milliseconds over millions of records.
