Abstract :
The covert storage channels found in disk I/O optimization schemes are studied. The authors examine the source of the problems in the context of various disk architectures, propose several classes of generic solutions and conclude with recommendations for future storage-system architectures. The work was done as part of the covert channel analysis for Digital´s VAX security kernel
