Abstract
Embodiments are directed to providing attribute-based data access. In an embodiment, a data request specifies one or more search data attributes describing requested data that is to be found in a data store. The data store is configured to provide access to secured data according to access controls defined by one or more clients. The secured data includes data that is associated with a particular client and that is encrypted using attribute-based encryption, which associates the data with one or more encryption data attributes and that enables the data to be provided if conditions in the corresponding access controls are met. The particular portion of data is provided based on determining that the conditions in the corresponding access controls are met, and that at least one of the search data attributes is determined to be relevant to at least one of the encryption data attributes.
