Documentation of service measures on a motor vehicle
First Claim
1. A method for documentation of service measures on a motor vehicle using an electronic memory, comprising the acts of:
- generating a hash value of input data which identifies at least one concrete service measure, encrypting the hash value using a personal key as part of a public key method, and inputting the input data, the encrypted hash value and a certificate including in plain text at least a public key complementary to the personal key and data on a key holder into the electronic memory.
