An efficient cryptographic technique using modified Diffie–Hellman in wireless sensor networks

International Journal of Distributed Sensor Networks, 2020
In wireless sensor networks, the sensors transfer data through radio signals to a remote base station. Sensor nodes are used to sense environmental conditions such as temperature, strain, humidity, sound, vibration, and position. Data security is a major

Analysis of the conjugacy search problem of the Diffie-Hellman protocol based on the SL(2,3) subgroup [PDF]

ITM Web of Conferences
The purpose of the Diffie-Hellman key exchange is to establish a shared secret key given that the protocol works in an abelian group setting. In this paper, conditions are presented to attain a shared secret key over a nonabelian group for the well-known

Variants of the Diffie-Hellman Problem

, 2018
Many variations of the Diffie-Hellman problem exist that can be shown to be equivalent to one another. We consider following variations of Diffie-Hellman problem: square computational and Square decisional Diffie-Hellman problem, inverse computational ...

Diffie-Hellman without Difficulty

, 2011
An excellent way for a protocol to obtain shared keys is Diffie-Hellman. For the automated verification of security protocols, the use of Diffie-Hellman poses a certain amount of difficulty, because it requires algebraic reasoning.

A Probability‐Aware AI Framework for Reliable Anti‐Jamming Communication

CAAI Transactions on Intelligence Technology, Volume 11, Issue 2, Page 349-366, April 2026.
ABSTRACT Adversarial jamming attacks have increased on communication systems, causing distortion and threatening transmissions. Typical attacks rely on traditional, well‐defined cryptographic protocols and frequency‐hopping techniques. Nevertheless, these techniques become vulnerable when facing intelligent jammers.
