Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO CON EL CUAL PUEDE CONVENIRSE UNA CLAVE DE SESION (K) ENTRE UNA PRIMERA UNIDAD DE ORDENADOR (U) Y UNA SEGUNDA UNIDAD DE ORDENADOR (N) SIN QUE UN TERCERO NO AUTORIZADO PUEDA OBTENER INFORMACION UTIL RELATIVA A LA CLAVE O A LA IDENTIDAD DE LA PRIMERA UNIDAD DE ORDENADOR (U). ELLO SE CONSIGUE MEDIANTE LA INCLUSION DEL PRINCIPIO DE INTERCAMBIO DE CLAVES E1-GAMAL EN EL PROCEDIMIENTO DE LA INVENCION CON LA FORMACION ADICIONAL DE UNA FIRMA DIGITAL MEDIANTE EL VALOR ''HASH'' DE LA CLAVE DE SESION (K) FORMADA POR LA PRIMERA UNIDAD DE ORDENADOR (U).
