Zusammenfassung:A trusted authority is provided for identifier-based cryptography. The trusted authority has a secret and derives first and second elements at least the second of which it publishes. The first element is derived from an identifier associated with the trusted authority; the second element is a combination of the first element and the secret. The trusted authority provides a private-key generation service involving the generation of a private key for a third party in dependence on the secret and an identifier string associated with that third party.
