ABSTRACT

While the secure concurrency control schemes in multilevel secure database management systems synchronize transactions cleared at different security level they must consider the problem covert channel. although previous works achieve the confidentiality successfully, they overlook the integrity or the availability. For being evaluated as highly secure database systems , the multilevel secure database management systems must achieve the confidentiality, integrity, and the availability that are the well-known major security aspects. By use of verified transactions ordering relationship, in this paper, we propose a new secure concurrency control scheme that is capable of increasing the degree of fairness among transactions cleared at different security levels.
