A Public Key Exchange Cryptosystem Based on Ideal Secrecy
one way function ideal secrecy asymmetric key cryptography
2018/11/29
This paper proposes two closely related asymmetric key (or a public key) schemes for key exchange whose security is based on the notion of ideal secrecy. In the first scheme, the private key consists ...
Public key exchange protocol is identified as an important application in the field of public-key cryptography. Most of the existing public key exchange schemes are Diffie-Hellman (DH)-type, whose sec...
Public key exchange using semidirect product of (semi)groups
public-key cryptography public key exchange
2014/3/13
In this paper, we describe a brand new key exchange protocol based on a semidirect product of (semi)groups (more specifically, on extension of a (semi)group by automorphisms), and then focus on practi...
Public Key Exchange Using Matrices Over Group Rings
public-key cryptography / public key exchange
2013/4/18
We offer a public key exchange protocol in the spirit of Diffie-Hellman, but we use (small) matrices over a group ring of a (small) symmetric group as the platform. This ``nested structure" of the pla...
