Nowadays, developments in the car industry result in more and more complicated technologies. Broader communication bandwidths are demanded by a lot of developments. The safety-critical steering and brake systems in tomorrow’s cars will not contain any mechanical connection, thus a complicated encryption is needed for the car to be protected against external attacks. Thereby, the required bandwidth can be way broader, than what the effective data would need. Moreover, the state-of-the-art driver assistant systems also communicate with large data packs, more and more applications need to transmit sounds, and even uncompressed videos through the communication channels.
However, the communication protocols, that were used until nowadays, cannot comply with the growing needs of the car industry. This way, the importance of new communication protocols grows significantly. Probably the most promising of them is the Automotive Ethernet protocol.
The goal of this thesis is to give an overview of the main communication protocols used in the car industry, to present the Automotive Ethernet standard, and – as this is the first part of a long-time development – to plan an environment that makes the communication and different encryption algorithms easy to test.
