Title: Keeping Data Private in the Cloud Using Homomorphic Encryption


Many applications handle data that are very sensitive, but nevertheless wants to use the processing capability of the cloud.

In particular, the ability to make use of cloud processing capabilities for very large datasets is attractive.
Up till now we have had to decide if we want to trust those data to the provider or abstain from the processing capabilities the provider can offer.

However, a recent advance in cryptology opens up the possibility for letting the provider side do the computational work on such sensitive data without having access to the contents of the data: Homomorphic encryption.
