题目: Security Problems and Solutions from the Data Angle







The fast evolution of Mobile, Web, and Cloud has provided us with a new platform for information services and computing. This platform raises new challenges to system and data security. It is a complex platform consisting of many different types of systems. The security policies, software qualities, etc., are diverse, and cannot be tightly controlled by a single standard. Traditional security mechanisms, such as access control and isolation of privileges, are not sufficient to provide sufficient protection in such a platform. In this talk, we look into the security problems and solutions of this platform from the data angle: how to provide users with strong data-oriented protection, where data are protected by users' security requirement even when part of the platform is not trusted. We will discuss our solution in the mobile and web platform. In addition, we will also discuss our recent work in data-oriented exploits in the traditional desktop platform.
