Abstract
A method of secure data export from an automotive ECU to a requesting entity includes receiving a signed request, the request transmitting a first public encryption key. The signature is verified using a second public key stored in the automotive ECU. Further, the requesting entity is authenticated. Only upon successful verification and authentication the automotive ECU generates a random symmetric key for encrypting the data to be exported. The symmetric key is encrypted using the first public key received in the request, and unencrypted data is deleted. The encrypted data is exported to the requesting entity, which decrypts the symmetric key using a first private key associated with the first public key, and decrypts the data encrypted with the symmetric key.
