Abstract
Self-Certified keys provide an attractive alternative to traditional certificate-based public key infrastructures. Many self-certified key issuing protocols strive to blind trusted third parties to users ’ private keys. One such key issuing protocol is based on the Nyberg-Rueppel signature scheme, but requires a proof of knowledge to avoid impersonation attacks. This paper describes a version of this protocol that uses elliptic curves and eliminates the impersonation attacks and the proof of knowledge.
