Abstract

Se describen un método y aparato de autenticación de mensajes de red de área del controlador. Un ejemplo de vehículo descrito incluye una barra de distribución de datos y una primera unidad de control acoplada de forma comunicativa a la barra de distribución de datos. El ejemplo de primera unidad de control genera un mensaje seguro (a) calculando un código de autenticación del mensaje, (b) truncando el código de autenticación del mensaje (c) truncando el valor actualización que se utiliza para generar el código de autenticación del mensaje y (d) colocando partes del código de autenticación del mensaje truncado y el valor de actualización truncado en partes separadas del mensaje seguro.
