SecureBus: towards application-transparent trusted computing with mandatory access control

The increasing number of software-based attacks has attracted substantial efforts to prevent applications from malicious interference. For example, Trusted Computing (TC) technologies have been recently proposed to provide strong isolation on application platforms. On the other hand, today pervasively available computing cycles and data resources have enabled various distributed applications that require collaboration among different application processes. These two conflicting trends grow in parallel. While much existing research focuses on one of these two aspects, a few authors have considered simultaneously providing strong isolation as well as collaboration convenience, particularly in the TC environment. However, none of these schemes is transparent. That is, they require modifications either of legacy applications or the underlying Operating System (OS). In this paper, we propose the SecureBus (SB) architecture, aiming to provide strong isolation and flexible controlled info...
