Abstract
Methods, systems, and computer-readable media for generating a secured hierarchical document are described herein. A hierarchical document is obtained and is processed to generate a secured hierarchical document. A security label is applied to each node in the hierarchical document. The secured hierarchical document is generated by cryptographically segregating the nodes according to the security label of each node. The secured hierarchical document comprises a plurality of encrypted layers. Each encrypted layer comprises at least a subset nodes associated with a respective security label and encrypted with a respective encryption key. The secured hierarchical document is stored to computer-readable memory. Methods, systems, and computer-readable media for searching a corpus of secured hierarchical documents indexed in an index as sensitive information by a computing entity trusted to have access to the sensitive information in the index are also described herein.
