| Abstract | The classical Early Prepare commit protocol (EP), used in many commercial systems, is not suitable for use in multilevel secure distributed databases systems that employ a locking protocol for concurrency control. This is because EP requires that read locks are not released by a participant during its window of uncertainty; however, it is not possible for a locking protocol to provide this guarantee in a multilevel secure system (since the read lock of a higher level transaction on a lower level data object must be released whenever a lower level transaction wants to write the same data). The only available work in the literature, namely the Secure Early Prepare protocol (SEP), overcomes this difficulty by aborting those distributed transactions that release their low level read locks prematurely. We see this approach as being too restrictive. |
