ASSERTION MESSAGE SIGNATURES

摘要

The invention relates to a method for providing an assertion message (200) from a proving party (20) to a relying party (40), the method comprising the steps of: - creating an assertion (A) comprising one or more statements, - creating an assertion proof (p A), - creating a temporary private key and a corresponding temporary public key (K) from the assertion (A) and the assertion proof (p A), - creating a key proof (PK) for the temporary public key (K), - creating an assertion message signature (S) by means of the temporary private key, - creating the assertion message (200) comprising the temporary public key (K), the assertion proof (PA), the key proof (PK), the assertion (A), a message body (220) and the assertion message signature (S) to the relying party (40).
