Abstract

Sistema para la protección anti-copia y gestión de licencias de software, que usa un dispositivo procesador resistente a ataques físicos (p.ej. una tarjeta inteligente) conteniendo un par de claves asimétricas, basado en que durante la fase de producción del software se sustituyen algunas secciones por código que debe ejecutarse en el dispositivo, siendo tales secciones cifradas mediante un criptosistema simétrico. Para el uso del software se genera una licencia cifrada con la clave pública del dispositivo (y por tanto específica para el mismo) que contiene, entre otras cosas, la clave simétrica con la que se cifraron las secciones de código protegidas e información acerca de las condiciones de uso. Esta licencia queda almacenada en el dispositivo, que posteriormente la gestiona y la usa para la ejecución del software. También está prevista su aplicación para protección de software y datos en entornos de computación móvil y comercialización de información.
