Original Titel:
SemCrypt - Secure XML Processing in Outsourced Databases
Sprache des Titels:
Englisch
Original Kurzfassung:
The increasing number and size of XML documents require efficient techniques for storing, querying and updating XML data. Current XML databases disregard privacy and security concerns when processing sensitive documents at external storage providers because they cannot prevent the untrustworthy storage provider from accessing either the content or the structure of the outsourced documents. At the external storage provider, SemCrypt1 exclusively processes encrypted documents. Documents or document fragments are only decrypted at the client-side for authorized users. To query and update encrypted documents, the approach developed explores the structural semantics of the documents as well as special index structures. The SemCrypt database provides an administration tool that visualizes how data is stored and processed.
