【Abstract】 This paper presents the design of a kind of intrusion tolerant database system,the purpose of which is to guarantee the completeness and reliability of the data in the case of that the database is attacked.Using a rule-based adaptation mechanism and a set of reconfiguration operators,the system adapts itself to the dynamic changes of environment according to a specific set of adaptation criteria.And the rules are based on the current situation of the attacks,the damage,the workload,the performance,and the cost.更多还原
