Onboard embedded network file access control method based on static allocation list

The invention relates to an onboard embedded network file access control method based on a static allocation list. The onboard embedded network file access control method includes the following steps that firstly, a network file system is divided into a file access module, an authorization data managing module and an authorization allocation tool according to a logic function; secondly, a user generates the static allocation list according to a demand utilization authorization allocation tool; thirdly, the user sends a file operation request through a network file operation interface and the file operation request comprises an operation object and file operation; fourthly, a client terminal judges whether an operation object belongs to a local node or a remote node according to the received file operation request. The onboard embedded network file access control method based on the static allocation list is used for solving the problem of safety of onboard embedded network file sharing, can meet the requirements that an onboard application supports node isolated allocation and maintenance is convenient to carry out and can ensure file access safety at an onboard distributed application software integration stage.
