Abstract
A terminal device according to the present invention includes: a first domain configured to execute multiple software programs; and a second domain configured to operate independently of the first domain and to check whether or not the software programs are safe. The second domain includes: an execution sequence storage unit configured to store execution priority of the multiple software programs to be executed by the first domain; a software program checking unit configured to check whether or not the multiple software programs are safe, according to the execution sequence storage unit; and an execution restricting unit configured to restrict the first domain from executing a software program included in the multiple software programs and having a check result indicating that the software program is unsafe, before checking of all the multiple, software programs is completed.
