Modifying The Tropical Version of Stickel’s Key Exchange Protocol
Stickel’s protocol Tropical Algebra Cryptography
2019/8/2
A tropical version of Stickel’s key exchange protocol was suggested by Grigoriev and Sphilrain [2] and successfully attacked by Kotov and Ushakov [5]. We suggest some modifications of this scheme that...

2018/1/2
In November 2017, Juan edro Hecht and Jorge Alejandro Kamlofsky submitted a quaternions/octonions based Diffie-Hellman key agreement protocol HK17 to NIST post quantum cryptography project. Daniel J. ...
Comparison analysis and efficient implementation of reconciliation-based RLWE key exchange protocol
RLWE Post Quantum Key Exchange
2017/12/11
Error reconciliation is an important technique for Learning With Error (LWE) and Ring-LWE (RLWE)-based constructions. In this paper, we present a comparison analysis on two error reconciliation-based ...
A Faster Software Implementation of the Supersingular Isogeny Diffie-Hellman Key Exchange Protocol
SIDH protocol Montgomery ladder post-quantum cryptography
2017/10/19
Since its introduction by Jao and De Feo in 2011, the supersingular isogeny Diffie-Hellman (SIDH) key exchange protocol has positioned itself as a promising candidate for post-quantum cryptography. On...
Provably Secure Three-party Password Authenticated Key Exchange Protocol Based On Ring Learning With Error
Key Exchange Three-Party PAKE Lattice
2017/4/27
Three-party Password Authenticated Key Exchange (3PAKE) protocol is an important cryptographic primitive, where clients can establish a session key using easy-to-remember passwords. A number of 3PAKE ...
Comments on “Flaw in the Security Analysis of Leakage-resilient Authenticated Key Exchange Protocol from CT-RSA 2016 and Restoring the Security Proof”
public-key cryptography Security Analysis
2016/12/15
In CT-RSA 2016, Chen, Mu, Yang, Susilo and Guo proposed a strongly leakage-resilient authenticated key exchange (AKE) protocol. In a rencent work, Chakraborty et al. claimed that they identified a fla...
