Symmetrically and Asymmetrically Hard Cryptography [PDF]

open access: yes, 2017
The main efficiency metrics for a cryptographic primitive are its speed, its code size and its memory complexity. For a variety of reasons, many algorithms have been proposed that, instead of optimizing, try to increase one of these hardness forms.We present for the first time a unified framework for describing the hardness of a primitive along any of ...

Application Of Rectangular Matrices: Affine Cipher Using Asymmetric Keys

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2019
In cryptography, we know the symmetric key algorithms and asymmetric key algorithms. We know that the asymmetric key algorithm is more secure than the symmetric key algorithm. Affine Cipher uses a symmetric key algorithm.

Categorical composable cryptography: extended version [PDF]

open access: yesLogical Methods in Computer Science, 2023
We formalize the simulation paradigm of cryptography in terms of category theory and show that protocols secure against abstract attacks form a symmetric monoidal category, thus giving an abstract model of composable security definitions in cryptography.
