On Bitcoin Security in the Presence of Broken Cryptographic Primitives [PDF]
, 2016 Digital currencies like Bitcoin rely on cryptographic primitives to operate. However, past experience shows that cryptographic primitives do not last forever: increased computational power and advanced cryptanalysis cause primitives to break frequently, and motivate the development of new ones.

THE TABULAR OF CRYPTOGRAPHIC PRIMITIVES OF NONLINEAR SUBSTITUTIONS
Ìнформаційні технології в освіті, 2015 Classic primitives nonlinear substitution is a simple replacing each character encrypted text on a fixed symbol of the same alphabet, actually realizing the transformation one alphabet simple substitution cipher. And as a consequence - the entropy cipher

Signcryption schemes with insider security in an ideal permutation model
Journal of Mathematical Cryptology, 2019 Signcryption aims to provide both confidentiality and authentication of messages more efficiently than performing encryption and signing independently. The “Commit-then-Sign & Encrypt” (CtS&E) method allows to perform encryption and signing in parallel ...

Cryptographic primitives based on compact knapsack problem
Journal of Information Security and ApplicationsIn the present paper, we extend previous results of an id scheme based on compact knapsack problem defined by one equation. We present a sound three-move id scheme based on compact knapsack problem defined by an integer matrix. We study this problem by providing attacks based on lattices.

Automated Generation of Fault-Resistant Circuits
Transactions on Cryptographic Hardware and Embedded SystemsFault Injection (FI) attacks, which involve intentionally introducing faults into a system to cause it to behave in an unintended manner, are widely recognized and pose a significant threat to the security of cryptographic primitives implemented in ...
