摘要
隐通道对安全数据库的危害是不言而喻的,通过对隐通道产生的分析,总结了几种避免隐通道的算法,通过对算法的模拟可以发现其均能够消除低安全级事务对高安全级事务的递交依赖,从而避免隐通道的产生。
Covert channel endanger the safety database is self-evident, covert channel analysis, summarizes several algorithms to avoid covert channels through the simulation of the algorithm can be found to eliminate the low security level transaction dependent on the submission of high security level transaction, thus avoiding the generation of the covert channel.
