(English Abstract) |
Preventing the creation of covert channels in concurrency control is the most important issue in the database security, i.e., ensuring secret information keep secret from unauthorized users. Developing secure concurrency control mechanisms, however, often incurs additional problems including the starvation of high transactions and the possibility of non-serializable schedule due to the execution of low transactions. We, in this paper, propose a secure multiversion concurrency control algorithm based on the concepts of a C-set and a T-lock. The main objective of our algorithm is to make the high security level transactions free from starvation incurred by retrieval anomaly. We also show that our algorithm satisfies the security and correctness requirements.
