Failure analysis system, application execution device, failure analysis device and failure analysis method

摘要

PROBLEM TO BE SOLVED: To analyze a fault, while ensuring security.SOLUTION: In a fault analysis system, an application execution apparatus 1 includes: a conversion table storage section 3 which stores a conversion table for associating multiple pieces of pre-conversion information with one piece of post-conversion information; and a conversion processing section 4 which converts fault related information on a fault of an application into post-conversion fault related information including the post-conversion information, on the basis of the conversion table. A fault analysis apparatus 2 includes: a reverse conversion table storage section 5 which stores a reverse conversion table for associating one piece of post-conversion information with multiple pieces of pre-conversion information; a reverse conversion processing section 6 which reversely converts the post-conversion fault related information into fault verification information including at least one piece of the pre-conversion information, on the basis of the reverse conversion table; and a fault verification section 7 which verifies the application, on the basis of the fault verification information reversely converted.SELECTED DRAWING: Figure 1
