The need for vehicular data security and privacy protection is already enormous and increases even further. Prominent application areas are for instance theft protection, anti-counterfeiting, secure data storage and secure communication inside the vehicle and from the vehicle to the outside world. However, most of the vehicular security and privacy protection solutions involve modern cryptography and require availability of cryptographic keys in the vehicle and in related backend infrastructure. A central aspect for ensuring this availability and a controlled usage of such cryptographic keys is a secure key management, which affects the whole lifecycle of the key, from creation and distribution, usage, backup and update up to key deactivation.
