Security Analysis of the MOR Cryptosystem

The paper cryptanalyses a new public key cryptosystem that has been recently proposed by Paeng, Ha, Kim, Chee and Park [5]. The scheme works on finite non-abelian groups. We focus on the group SL(2, ZZp)×θ ZZp which was discussed in [5] extensively.

Public key cryptosystem and a key exchange protocol using tools of non-abelian group

Abstract. Public Key Cryptosystems assure privacy as well as integrity of the transactions between two parties. The sizes of the keys play an important role. The larger the key the harder is to crack a block of encrypted data. We propose a new public key cryptosystem and a Key Exchange Protocol based on the generalization of discrete logarithm problem using Non-abelian group of block upper tria...

Design und Analyse kryptografischer Bausteine auf nicht-abelschen Gruppen

English Abstract Public-key cryptography enables two (or more) parties to execute cryptographic protocols (e.g. to send confidential messages) without requiring a common secret. The methods in use today are mostly based on abelian groups (see [35] for example). Recently, several cryptographic protocols using non-abelian groups were proposed [23, 42]. The underlying security assumption on which ...
