Toward Cloud-Based Key Management for Outsourced Databases

摘要

A major drawback of implementing Database-as-a-Service (DaaS) on untrusted servers is the complexity of key management required for handling revocation. In this paper we put forward the idea of using the cloud for decoupling the management of local, user-specific encryption keys from the one of role-specific protection keys, obtaining simple key management and revocation schemes.
