Findings
Developed a blind signature scheme from Paillier cryptosystem
Proposed a three-pass protocol using homomorphic property
Enhanced cryptographic toolkit with novel schemes
Abstract
Englisch: In this paper we study the paillier cryptosystem and derive form it to new schemes. First we transform the signature of paillier in a Blind signature. Secondly we propose a three-pass protocol wich use the homomorphic property instead of the commutativity as the Shamir protocol does. German: Basierend auf dem Kryptosystem von Paillier und dem damit eingef\"uhrten Problem der zusammengesetzten Residuenklasse werden in diesem Artikel zwei kryptographische Verfahren vorgeschlagen. Zun\"achst wird die Signatur von Paillier in ein blindes Signaturverfahren umgewandelt. Des Weiteren wird mit der homomorphen Eigenschaft des Kryptosystems von Paillier ein sogenanntes Three-Pass-Protocol - auch No-Key-Protocol genannt - entwickelt.
