摘　　要：LogicSQL数据库是自主研制基于Linux的高安全级别安全数据库。重点对安全数据库的隐蔽通道标识技术进行研究,为寻求更好的隐蔽通道标识方法,对共享资源矩阵、信息流公式法、无干扰法等标识方法从理论上进行分析,以Log-icSQL安全数据库的隐蔽通道进行实例分析。改进的共享资源矩阵是目前相对比较成功的隐蔽通道标识方法,无干扰法的实际应用可作以后的隐蔽通道标识方法研究重点。LogicSQL database was the independent development based on the Linux high security rank security database. Focus on covert channel logo technology research of security database, in the search for better methods of covert channel logo, for sharing resources matrix, information flow formula method, without interference method and logo technology from theoretical analysis, and covert channel examples analysis of LogicSQL database security. Improved sharing of resources matrix is relatively successful convert channel logo methods. And practical application of the method without interference can become future research priorities of convert channel logo methods.
