ESMVCC: AN ENHANCED SECURE REAL-TIME MULTIVERSION CONCURRENCY CONTROL ALGORITHM

Abstract

In addition to ensuring database integrity, secure concurrency control techniques must be free of covert channels emerging from data conflicts between transactions. Transactions with higher access classes are mistreated by current secure concurrency control techniques. Because it solves the priority inversion problem more effectively. This paper introduces and evaluates a novel secure multiversion concurrency control technique. These experiments show that when comparing the proposed concurrency control algorithm to the SMVCC concurrency control protocol, the proposed algorithm outperforms the SMVCC protocol in terms of total average response time. ESMVCC has the lowest overall average transaction response time and the highest level of fairness among secure concurrency control protocols.
