Abstract

For communication of a first participant with at least one additional participant in a communication system via multiple protocols, the protocols using at least two different certificate formats, the first participant uses different certificates with the respective certificate formats for the communication via the different protocols, the different certificates being based on a shared public key. The first participant holds a shared associated private key for the different certificates. Provision of the certificates for the first participant includes generating the public key and the associated private key, signing the public key for provision of the first certificate, and signing the public key for provision of the second certificate.
