Abstract

Several architectures have been recently proposed thatstore relational data in encrypted form on untrusted relationaldatabases. Such architectures permit the creation ofnovel Internet services and also offer an opportunity for abetter construction of ASP solutions. Environments wherethere are limited resources that do not permit an efficientmanagement of databases or where it is critical to offer arobust Internet access to private data may all benefit fromthe above architectures. In this paper we analyze the impactthat this architecture has on the typical services of adatabase. The analysis is based on the experience gainedin the construction of a prototype of a complete architecturefor the management of encrypted databases. Specifically,we illustrate the impact on query translation and optimization,and the main components of the software architectureof the prototype.
