Distributed database access control method based on improved genetic algorithms
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.
