Abrégé

The present disclosure relates to technology for correcting a regular expression that is vulnerable to ReDoS attacks. The purpose of the present disclosure is to ensure that a correction result having, as a subject, a regular expression including real-world extensions is not vulnerable while minimizing memory consumption.　For the aforementioned purpose, a correction device 30 carries out an iterative deepening depth-first search to thereby correct an inputted regular expression to a form that satisfies RWS1U (prohibits the same characters from appearing consecutively) by using the regular expression, a positive example, and a negative example, and then output the corrected regular expression. It is expected that this will make it possible to support development of a program that is safe against ReDoS in more scenarios.
