报告1： Flexible and Secure Access to Encrypted Data in the Cloud
Traditionally, access controls to data are enforced by employing trusted servers to store data and mediate access
control. However, services are increasingly storing data across many servers
shared with other data owners. An example of this is cloud computing which has the
great potential of providing various services to the society at significantly
reduced cost due to aggregated management of elastic resources. Since software
systems are not guaranteed to be bug-free and hardware platforms are not under direct
control of data owners in such distributed systems, security risks are
abundant. To mitigate users’ privacy concern about their data, a common
solution is to outsource data in encrypted form so that it will remain private
even if data servers are not trusted or compromised. The encrypted data, however,
must be amenable to sharing and access control. In this talk, I will discuss
various security issues related to outsourced data storage and provide an
overview of emerging solutions for realizing secure access to encrypted data in
