Subsets of groups in public-key cryptography [PDF]

arXiv, 2023
We suggest the usage of algebraic subsets instead of subgroups in public-key cryptography. In particular, we present the subset version of two protocols introduced by Shpilrain and Ushakov with some examples in ascending HNN-extensions of free-abelian groups and discuss their resistance to length and distance based attacks.

New approach to practical leakage-resilient public-key cryptography

Journal of Mathematical Cryptology, 2020
We present a new approach to construct several leakage-resilient cryptographic primitives, including leakage-resilient public-key encryption (PKE) schemes, authenticated key exchange (AKE) protocols and low-latency key exchange (LLKE) protocols.

A Design of Secure Communication Architecture Applying Quantum Cryptography

Journal of Information Science Theory and Practice, 2022
Existing network cryptography systems are threatened by recent developments in quantum computing. For example, the Shor algorithm, which can be run on a quantum computer, is capable of overriding public key-based network cryptography systems in a short ...

Adaptive authentication and key agreement mechanism for future cellular systems [PDF]

, 2006
Since the radio medium can be accessed by anyone, authentication of users is a very important element of a mobile network. Nowadays, in GSM/GPRS a challenge response protocol is used to authenticate the user to the mobile network.

A New Class of Strongly Asymmetric PKA Algorithms: SAA-5

Cryptography, 2019
A new class of public key agreement (PKA) algorithms called strongly-asymmetric algorithms (SAA) was introduced in a previous paper by some of the present authors.

Thompson’s Group and Public Key Cryptography [PDF]

, 2005
Recently, several public key exchange protocols based on symbolic computation in non-commutative (semi)groups were proposed as a more efficient alternative to well established protocols based on numeric computation. Notably, the protocols due to Anshel-Anshel-Goldfeld and Ko-Lee et al.

LPKI - A Lightweight Public Key Infrastructure for the Mobile Environments

, 2008
The non-repudiation as an essential requirement of many applications can be provided by the asymmetric key model. With the evolution of new applications such as mobile commerce, it is essential to provide secure and efficient solutions for the mobile ...

IMPLEMENTATION OF BLOM’S KEY PREDISTRIBUTION SCHEME BY USING ELLIPTIC CURVE CRYPTOGRAPHY

Malaysian Journal of Computing, 2021
Cryptography, along with its various methods is used to serve the security communication purpose. Cryptography is said to be secure if the encryption key is hard to break by the attacker.

Breaking the Hidden Irreducible Polynomials Scheme [PDF]

arXiv, 2019
In 2019 G\'omez described a new public key cryptography scheme based on ideas from multivariate public key cryptography using hidden irreducible polynomials. We show that the scheme's design has a flaw which lets an attacker recover the private key directly from the public key.
