This paper focuses on the protection of the confidentiality of the data space content when Shared Data Spaces are deployed in open, possibly hostile, environments. In previous approaches, the data space content was protected against access from unauthorised application components by means of access control mechanisms. The basic assumption is that the hosts (and their administrators) where the data space is deployed have to be trusted. When such an assumption does not hold, then encryption schemes can be used to protect the data space content from malicious hosts. However, such schemes do not support searching on encrypted data.
