Abstract:
Encryption can protect the confidentiality of data stored in the cloud, but also prevents search. To solve this
problem, searchable encryption schemes have been proposed that allow keyword search over document collections.
To investigate the practical value of such schemes and the tradeoff between security, functionality and
performance, we integrate a prototypical implementation of a searchable encryption scheme into a document-oriented
database. We give an overview of the performance benchmarking results of the approach and analyze
the threats to data confidentiality and corresponding countermeasures.
