Abstract
The present invention relates to a method for distributing a software file in a vehicle-to-vehicle communication network, executed by an ego vehicle. To ensure secure distribution, the ego vehicle first receives encoded data packets containing a digital signature from a trusted source. In a relay mode (6), the ego vehicle verifies the digital signature of the received data packets and forwards the successfully verified data packets to other vehicles without modification. After a sufficient number of data packets for reconstructing the software file has been received and their integrity has been successfully verified, the ego vehicle switches to an operating mode (9) referred to as source mode (9). In source mode (9), the ego vehicle autonomously generates new encoded data packets from the previously verified software file and sends them to other vehicles in the network.
