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 ConferencesThe 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

Easy Decision Diffie-Hellman Groups [PDF]
LMS Journal of Computation and Mathematics, 2004 AbstractThe decision Diffie-Hellman problem (DDH) is a central computational problem in cryptography. It is known that the Weil and Tate pairings can be used to solve many DDH problems on elliptic curves. Distortion maps are an important tool for solving DDH problems using pairings, and it is known that distortion maps exist for all super-singular ...

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics
Advanced Materials, EarlyView.Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.
