*Abstract*

Google and Amazon have turned their huge infrastructure into a cloud
computing environment and are aggressively recruiting businesses to run
applications on their platforms. Many top-tier IT vendors have been
promoting cloud computing as a new service model. However, serious
concern has been raised about the security and privacy on such a service
platform. Corporate users would need to protect their data running on
the cloud computing platform from the “untrusted” service provider.
Unfortunately, traditional encryption methods that aim at providing
“unbreakable'' protection are often not adequate because they are not
designed to support applications to be executed on the encrypted data.
In this seminar, the general problem of computing on encrypted data will
be discussed. The key issue is how to balance the need on security and
the requirement to perform computation. As a case study, the problem of
k-nearest neighbor (kNN) computation will be used to illustrate a new
model of secure computation on encrypted database.
