Distributed Security Management of Network Forensic Log

A distributed security management method of network forensic log is proposed and designed in this paper. The log agents and management gateway collect and forward the log records to the multi-management nodes. The log records are respectively dispersed into n shares by information dispersal arithmetic in the node, and the node stores the corresponding share and the hash values of all shares. The management node can reconstruct the log records through corresponding information in m (mn) random nodes and validate the integrity of the log records through the hash values of all shares.
