PROBLEM TO BE SOLVED: To improve safety in information processing by authenticating an encrypted execution code, for example, and executing only the execution code which is successfully authenticated. SOLUTION: A secure processor includes: a secure process identifier generating means 109 for generating a secure process identifier when a process generation instruction is issued, which is the secure process identifier to be compared with a secure process identifier corresponding to a page, where a secure page flag for indicating the correct authentication of the page storing the execution code is set, before executing the process corresponding to the execution code; and a process information holding means for holding the generated secure process identifier as information related to the process.
