An Improved Sealing Scheme for Trusted Storage

Abstract

According to trusted computing standard, sealing provides assurance that sealed messages are bound to a set of platform metrics specified by the message sender, it ensures the security of data, but it can't handle asynchronous operation under multiple processes environment. An improved sealing method is given in this paper based on trusted storage, by introducing Root of Trust for Reporting (RTR) and Stored Measurement Log (SML) which provide real-time validation of trusting state, and it solves asynchronous operation problem for multiple tasks.
