Abstract: A secure model was proposed which not only relied on prevention controls but also incorporated detect intrusion and tolerant intrusion. The model can detect intrusions and locate and repair the damage caused by intrusion based on transactions, which protect the database system and provide secure services to legitimate clients. The techniques of both redundancy and diversity were utilized for secret data storage. Threshold secret share approach was presented to protect confidential data based on Chinese remainder theorem.
