Method for processing messages and message processing device
First Claim
1. A method for processing roadside traffic/vehicle flow messages in a message processing device having at least one reception buffer, the reception buffer storing a plurality of messages, wherein each roadside traffic/vehicle flow message comprises at least one authentication element and a message content, the method comprising:
- receiving in a receiver of the message processing device, the plural roadside traffic/vehicle flow messages;
determining a characteristic variable of a priority for security checking each of the plurality of roadside traffic/vehicle flow messages based on respective message content of each of the plurality of roadside traffic/vehicle flow messages;
defining a processing sequence for security checking the plurality of roadside traffic/vehicle flow messages based at least in part on the at least one respective authentication element and the characteristic variable of the priority for security checking of each of the plurality of roadside traffic/vehicle flow messages stored in the reception buffer; and
performing the security checking of the roadside traffic/vehicle flow messages in accordance with the defined processing sequence.

Abstract
A message processing device for processing messages has at least one reception buffer, a message includes at least one authentication element and one message content. The message is received and stored in the reception buffer. A characteristic variable of a priority for security checking of the message is determined as a function of the message content. A processing sequence for further message processing for the security checking, taking into account the at least one authentication element of the messages in the reception buffer is defined and carried out as a function of the characteristic variable.

23. A message processing device for processing roadside traffic/vehicle flow messages, wherein each roadside traffic/vehicle flow message comprises at least one authentication element and message content, wherein the roadside traffic/vehicle flow message processing device comprises:
-
a receiver to receive the roadside traffic/vehicle flow message; at least one reception buffer to store the roadside traffic/vehicle flow message; a first computing unit to determine a characteristic variable of a priority for security checking of the roadside traffic/vehicle flow message as a function of the message content; and a second computing unit configured to define a processing sequence for further roadside traffic/vehicle flow message processing for the security checking based at least in part on the at least on the authentication element and the characteristic variable of the priority for security checking of the roadside traffic/vehicle flow messages stored in the reception buffer; and a third computing unit performing the security checking of the roadside traffic/vehicle flow messages in accordance with the defined processing sequence. - View Dependent Claims (24)
