Abstract

In this paper, we proposed an improved memory integrity protection scheme to provide real-time protection service. In addition, we for the first time propose a provably secure scheme that takes advantage of the "error inheritance" property, which can minimize the costly check process that is normally required before every access. The security of the proposed scheme is rigorously analyzed and the performance is measured. The peak performance of the new scheme can be improved by up to a factor of 5 over a previously proposed scheme based on Merkle Trees.
