Abstract

Aparato, sistema y método proporcionan validacion de la integridad de los datos transmitidos, transmitiendo periodicamente un valor truncado del resumen del mensaje con los paquetes de datos cifrados seleccionados. Se calcula un resumen del mensaje para los datos, se trunca en el valor truncado del resumen del mensaje y se anexa a una carga de trabajo cifrada, formada por el cifrado de los datos. El paquete de datos cifrados resultante se transmite por un sistema de comunicaciones a un receptor. El receptor extrae el valor truncado del resumen del mensaje y descifra la carga de trabajo cifrada para revelar los datos recibidos. Se calcula un resumen del mensaje local para los datos recibidos, se trunca para formar un valor truncado del resumen del mensaje local y se lo compara con el valor truncado del resumen del mensaje extraído del paquete de datos recibido. Si no coinciden los dos valores de resumenes de mensajes, se considera comprometida la integridad de los datos, que se vuelven a transmitir.Apparatus, system and method provide validation of the integrity of the transmitted data, periodically transmitting a truncated value of the message summary with the selected encrypted data packets. A message summary for the data is calculated, truncated at the truncated value of the message summary and appended to an encrypted workload, formed by data encryption. The resulting encrypted data packet is transmitted by a communications system to a receiver. The receiver extracts the truncated value from the message summary and decrypts the encrypted workload to reveal the received data. A summary of the local message for the received data is calculated, truncated to form a truncated value of the summary of the local message and compared to the truncated value of the message summary extracted from the received data packet. If the two message summary values do not match, the integrity of the data, which is transmitted again, is considered compromised.
