A Novel Approach to Safeguard against Insider Attacks
Wissenschaftliches Paper zu Sealed Cloud – Aufsatz in englischer Sprache: Sealed Cloud – A Novel Approach to Safeguard against Insider Attacks
Security and privacy have turned out to be major challenges of the further Internet evolution in general and cloud computing, in particular. This paper proposes a novel approach to safeguard against previously unimpeded insider attacks, referred to as Sealed Cloud. A canonical set of technical measures is described, which, in conjunction, sufficiently complicate and thus economically prevent insider access to unencrypted data. This paper shows the advantages versus end-to-end encryption relative to communication services. Another application of the Sealed Cloud, referred to as Sealed Freeze, provides a seminal solution to privacy issues pertaining to data retention.
