Abstract

Un dispositivo para proteger el programa de computo, particularmente el programa de computo de aplicacion distribuido libremente contra la utilizacion sin permiso del propietario de los derechos de autor. Mediante la codificacion del programa de computo que emplea una clave (k1) que es diferente de aquella clave (k2) que se emplea en la decodificacion, se obtiene la mejor proteccion contra la utilizacion no autorizada cuando la clave de decodificacion es mantenida en secreto por el usuario. La seguridad mejorada adicional se logra ejecutando adicionalmente la combinacion-separacion de la comunicacion entre el computador en el que se utiliza el programa de computo y la unidad externa en la cual está almacenada la clave de decodificacion. Así mismo, la unidad externa está colocada de manera que regresa a la computadora principal, el resultado de su procesamiento de datos recibidos desde la computadora principal, el resultado siendo utilizado en la ejecucion adicional del programa respectivo.
