Secure Data Management in Trusted Computing

Abstract

Abstract. In this paper we identify shortcomings of the TCG speci-fication related to the availability of sealed data during software and hardware life cycles, i.e., software update or/and hardware migration. In our view these problems are major obstacles for large-scale use of trusted computing technologies, e.g., in e-commerce, as adopters are concerned that the use of this technology might render their data inaccessible. We propose both software and hardware solutions to resolve these prob-lems. Our proposals could be easily integrated into the TCG specification and preserve the interests of involved parties with regard to security and availability as well as privacy. 1
