Modification, insertion and replay of data. Disclosure of secret data. Jamming the radio channel. The first two of these are the greatest threats for the prometheus services, especially the services for safer driving in pro-net. The convoy driving service, for example, relies on continuous correct communication between the cars in the convoy.
Malicious information can result in a disaster.
The third threat, disclosure of secret data, is not very important for most services mentioned above. At least, the threat doesn't affect traffic safety. In addition to the communication threats, the prometheus environment is exposed to other threats, which are outside the scope of pro-com. Protection against masquerading. The prometheus environment places special requirement on this service.
