Abstract

A method for asymmetrical key derivation by a signing entity for a terminal including introducing identical cryptographic material into the signing entity and into the terminal; deriving in each case a private key from the cryptographic material in the signing entity and in the terminal; calculating in each case a public key from the private key in the signing entity and in the terminal; generating a signature and/or a signed public key in the signing entity; transferring the signature and/or the signed public key from the signing entity into the terminal; and appending the signature of the signing entity to the public key in the terminal.
