Claim:
A process for the packet-oriented transmission of security-relevant data under application of at least one security-oriented message consisting of a first data packet and an allocated second data packet, and at least one transmission system with a parallel and/or serial network and/or bus system with at least one communication participant connected to it, the process, comprising: transmitting the security-relevant data and redundant information based on the security-relevant data within the at least one security-oriented message, wherein the security-relevant data and the redundant information each comprise the user data and the check data; wherein, for each security-oriented message, the security-relevant data is transmitted in the first data packet and the redundant information, based solely on all the security-relevant data of the first data packet, is transmitted in the allocated second data packet of the at least one security-oriented message, wherein the check data enables the communication participant to verify the proper function of the other communication participants via checking a transmission path over signal chains by exchanging the check data, and wherein the security-relevant data is provided by a device selected from the group consisting of a sensor, an actuator, a control device, and any combinations thereof.
