Cryptanalysis of Xinyu et al.'s NTRU-Lattice Based Key Exchange Protocol

Xinyu et al. proposed a public key exchange protocol, which is based on the NTRU-lattice based cryptography. In this paper, we show how Xinyu et al.’s NTRU-KE: A lattice based key exchange protocol can be broken, under the assumption that a man-in-the middle attack is used for extracting private keys of users who participate in the key exchange protocol.

NTRU-KE: A Lattice-based Public Key Exchange Protocol

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 security is based on DH problems over different groups. Note that there exists Shor’s polynomial-time algorithm to solve these DH problems when a quantum computer is available, we are therefore motiva...

Cryptanalysis of the dragonfly key exchange protocol

Dragonfly is a password authenticated key exchange protocol that has been submitted to the Internet Engineering Task Force as a candidate standard for general internet use. We analyzed the security of this protocol and devised an attack that is capable of extracting both the session key and password from an honest party. This attack was then implemented and experiments were performed to determi...

Cryptanalysis of a noncommutative key exchange protocol

In the papers by Alvarez et al. and Pathak and Sanghi a noncommutative based public key exchange is described. A similiar version of it has also been patented (US7184551). In this paper we present a polynomial time attack that breaks the variants of the protocol presented in the two papers. Moreover we show that breaking the patented cryptosystem US7184551 can be easily reduced to factoring. We...

Cryptanalysis of an identity-based authenticated key exchange protocol

Authenticated Key Exchange (AKE) protocols represent an important cryptographic mechanism that enables several parties to communicate securely over an open network. Elashry, Mu and Susilo proposed in 2015 an Identity Based Authenticated Key Exchange (IBAKE) protocol where different parties establish secure communication by means of their public identities. The authors also introduced a new secu...
