A Secure Time-Stamp Based Concurrency Control Protocol For Distributed Databases

Shashi Bhushan, R. B. Patel and Mayank Dave

Abstract

In distributed database systems the global database is partitioned into a collection of local databases stored at different sites. In this era of growing technology and fast communication media, security has an important role to play. In this paper we presented a secure concurrency control protocol (SCCP) based on the timestamp ordering, which provides concurrency control and maintains security. We also implemented SCCP and a comparison of SCCP is presented in three cases (High, Medium and Low security levels). In this experiment, It is observed that throughput of the system decreases as the security level of the transaction increases, i.e., there is tradeoff between the security level and the throughput of the system.
