Equivalent keys in ℳultivariate uadratic public key systems [PDF]

open access: yesJournal of Mathematical Cryptology, 2011
ℳultivariate uadratic public key schemes have been suggested as early as 1985 by Matsumoto and Imai as an alternative for the RSA scheme. Since then, several schemes have been proposed, for example hidden field equations, unbalanced oil and vinegar ...

A Novel Chaotic Image Encryption Scheme Armed with Global Dynamic Selection

open access: yesEntropy, 2023
Due to the equivalent keys revealed by a chosen-plaintext attack or a chosen-ciphertext attack, most of the existing chaotic image encryption schemes are demonstrated to be insecure.

Security Analysis of the Image Encryption Algorithm Based on a Two-Dimensional Infinite Collapse Map

open access: yesEntropy, 2022
This paper analyzes the security of the image encryption algorithm based on a two-dimensional (2D) infinite collapse map. The encryption algorithm adopts a permutation–diffusion structure and can perform two or more rounds to achieve a higher level of ...

A Triple Unlocking Mechanism Model Against Forging Signature Attack Based on Multivariate Polynomial Public Key Cryptosystem

open access: yesIEEE Access, 2023
Since the original signature model did not account for the possible threat of the forging signature attack, the majority of existing multivariate polynomial public key based signature schemes are at risk of forging signatures by equivalent key attacks ...

Improved Equivalent Method for Large-Scale Wind Farms Using Incremental Clustering and Key Parameters Optimization

open access: yesIEEE Access, 2020
Large-scale wind farms (WFs) generally consist of hundreds of wind turbines (WTs), and the WFs simulation model construction would be complex and even impossible if we develop each individual WT in detail.

Key Issues on the Design of an Offshore Wind Farm Layout and Its Equivalent Model

open access: yesApplied Sciences, 2019
Offshore wind farms will have larger capacities in the future than they do today. Thus, the costs that are associated with the installation of wind turbines and the connection of power grids will be much higher, thus the location of wind turbines and the
