Zusammenfassung:The invention allows a creator of a key pair-a public and a private key-to associate user data with the public key in such a way that verification data needed to cryptographically verify the association can be made public without compromising the key pair. An integer for use as a public exponent in the public key is derived such that it is a function of the user data to be associated with the public key.
