Full text available as: AbstractSometimes there is a need to store sensitive data on an untrusted
database server. Song, Wagner and Perrig have introduced a way
to search for the existence of a word in an encrypted textual document.
The search speed is linear in the size of the document. It does not scale
well for a large database. We have developed a tree search algorithm
based on the linear search algorithm that is suitable for XML databases.
It is more efficient since it exploits the structure of XML. We have built
prototype implementations for both the linear and the tree search case.
Experiments show a major improvement in search time. | Item Type: | Conference or Workshop Paper (Full Paper, Talk) |
