ソフトウェアアプリケーションを実行するための方法、システム及びセキュアプロセッサ

摘要

A host (110) reads host software code (131) and secure processor software code (132) of an software application (130) and passes the secure processor software code (132) to the secure processor (120) that requests an activation sequence (133) for the software application (130) from a remote server (260). The secure processor (120) receives the activation sequence (133) for the software application (130) and applies it to the secure processor software code (132) to make it executable. The host (110) executes the host software code (131) and calls a procedure of the executable secure processor software code (132) in the secure processor (120), which executes the procedure of the executable secure processor software code (132) to obtain a response to the call that is then returned. The activation sequence (133) is advantageously software code. The invention can enable protection of a plurality of software titles using a single secure processor that is dynamically adapted for each title.
