Trust Through Origin and Integrity: Protection of Client Code for Improved Cloud Security

Keywords: cloud security; integrity attestation; trusted computing; Google ChromeOS

Abstract:
Military computing is migrating to cloud architecture for several reasons, one of them is the opportunities for improved security management. One opportunity is to ensure that cloud clients are running approved and untainted program code, provided as a proof presented to the cloud service. Such proofs can extend the trust in the client’s integrity further than what traditional access control protocols can provide. While access control protocols can ensure that a computer is operated by authorized and trained personnel, they cannot ensure that the client computer is unaffected by malware or poor software control. Problems related to illegitimate program code cannot, in general, be solved by traditional security protocols. The contribution of this paper is an arrangement whereby proof of software approval and integrity can be established, exchanged and validated during service invocations. The demonstration program is a chat forum where the exchanged messages are signed and validated in the client computers, a typical use case which may benefit from our contribution. Two different client-server protocols were tested in order to study the applicability of our contribution.
