摘要
分布式数据库具有一定开放性和复杂性,使得数据库面临严峻的安全挑战,为此,文章提出了基于改进遗传算法的分布式数据库访问控制方法。首先,生成分布式数据库用户的SPKI/SDSI证书链,采用参数自适应改进的遗传算法搜索SPKI/SDSI证书链,然后,构建一个基于SPKI/SDSI证书的分布式访问控制模型,通过该模型对用户访问请求中的证书链进行搜索与验证,实现分布式数据库访问控制。实验结果表明,该设计方法可准确且快速地识别恶意分布式节点,并限制其任何访问行为,保障分布式数据库的安全。
Due to the openness and complexity of the distributed database,the database is faced with severe security challenges,and the distributed database access control method based on the improved genetic algorithm is proposed.The SPKI/SDSI certificate chain of distributed database users adopts the parameter adaptive genetic algorithm to search for SPKI/SDSI certificate chain,and then builds a distributed access control model based on SPKI/SDSI certificate.Through the model,the certificate chain in the user access request is searched and verified to realize distributed database access control.The experimental results show that the design method can accurately and quickly identify malicious distributed nodes,and limit any access behavior to ensure the security of distributed database.
