Abstract

UNA DISPOSICION PARA PROTEGER EL SOFTWARE, ESPECIALMENTE EL SOFTWARE DE APLICACION DISTRIBUIDO LIBREMENTE, CONTRA EL USO NO AUTORIZADO POR EL TITULAR DEL COPYRIGHT. CODIFICANDO EL SOFTWARE UTILIZANDO UNA CLAVE (K1) QUE ES DIFERENTE DE LA CLAVE (K2) QUE SE UTILIZA EN LA DESCODIFICACION, SE OBTIENE UNA MEJOR PROTECCION CONTRA EL USO NO AUTORIZADO CUANDO EL USUARIO MANTIENE EL SECRETO DE LA CLAVE DE DECODIFICACION. LA SEGURIDAD MEJORADA SE CONSIGUE EJECUTANDO ADICIONALMENTE ALEATORIZACION-DESALEATORIZACION DE LA COMUNICACION ENTRE EL ORDENADOR EN EL QUE SE UTILIZA EL SOFTWARE Y LA UNIDAD EXTERNA EN QUE SE ALMACENA LA CLAVE DE DECODIFICACION. ASIMISMO, LA UNIDAD EXTERNA ESTA DISPUESTA DE FORMA QUE DEVUELVE AL ORDENADOR PRINCIPAL EL RESULTADO DEL PROCESAMIENTO DE LOS DATOS RECIBIDOS DEL ORDENADOR PRINCIPAL, SIENDO UTILIZADO EL RESULTADO EN LA EJECUCION POSTERIOR DEL PROGRAMA RESPECTIVO.
