Abstract:
(EN) In the present invention, a client device (200) operates on multiple threads. A control unit (303) receives a decryption key from a server device (100) in a main thread. After receiving the decryption key from the control unit (303), the decryption-compilation unit (305) receives, from the server device (100) and in a sub-thread, an encrypted program obtained by using a server device (100) to encrypt a pre-compilation program, decrypts the received encrypted program using a decryption key to obtain the pre-compilation program, and compiles the pre-compilation program thus obtained.
(FR) Dans l'invention, un dispositif client (200) fonctionne sur de multiples fils. Une unité de commande (303) reçoit une clé de déchiffrement d'un dispositif serveur (100) dans un fil principal. Après avoir reçu la clé de déchiffrement de l'unité de commande (303), l'unité de déchiffrement-compilation (305) reçoit, du dispositif serveur (100) et dans un sous-fil, un programme chiffré obtenu à l'aide d'un dispositif serveur (100) afin de chiffrer un programme de pré-compilation, puis déchiffre le programme chiffré reçu à l'aide d'une clé de déchiffrement afin d’obtenir le programme de pré-compilation et compile le programme de pré-compilation ainsi obtenu.
(JA) クライアント装置(200)は、マルチスレッドで動作する。制御部(303)は、メインスレッドにおいて、サーバ装置(100)から復号鍵を受信する。復号コンパイル部(305)は、制御部(303)による復号鍵の受信後に、サブスレッドにおいて、サーバ装置(100)から、コンパイル前のプログラムがサーバ装置(100)で暗号化されて得られた暗号化プログラムを受信し、受信した暗号化プログラムを復号鍵を用いて復号してコンパイル前のプログラムを取得し、取得したコンパイル前のプログラムをコンパイルする。
