A method is provided for generating on-demand cryptographic keys in a vehicle-to-vehicle communication system. At least one unique identifier is obtained relating to a user of the vehicle. The host vehicle generates cryptographic keys for encrypting, decrypting, and authenticating secured messages between the host vehicle and at least one remote vehicle in the vehicle-to-vehicle communication system. The cryptographic keys are generated as a function of the at least one unique identifier. A respective cryptographic key used to decrypt or encrypt messages communicated between the host vehicle and the at least one remote entity is temporarily stored in a memory device of the host vehicle. The host vehicle utilizes the respective cryptographic key to decrypt or encrypt a secure message transmitted between the host vehicle and the remote vehicle. The respective cryptographic key temporarily stored in the memory device of the host vehicle is deleted after the vehicle-to-vehicle communications of the host vehicle is disabled. |
