Abstract
A method for deriving a verification token from a credential may be provided. The credential may be a set of attributes certified by an issuer to a user using a public key of the issuer. The method may comprise generating the verification token out of the credential and binding the verification token to a context string, wherein the verification token may comprise at least one commitment. A commitment may be a blinded version of an attribute. The method may also comprise generating an opening key for the verification token enabling a generation of a confirmation for a validity of the attribute.
