N2 - In this paper we present a dependable Email repository service that explores multiple untrusted cloud storage repositories for storing, accessing and searching private Email data. The system architecture provides security and reliability services while leveraging the heterogeneity and diversity offered by different untrusted cloud storage solutions from different service providers. To address dependability issues, TMS enforces a security model that protects confidentiality and integrity of mailboxes stored in those clouds, adding availability, reliability and intrusion-tolerance guarantees. The system uses homomorphic encryption mechanisms and indexing techniques allowing ranked multi-keyword searching operations over encrypted Email messages and its contents. We illustrate TMS feasibility from an implemented prototype, evaluating its performance, design options, and services.
