AIM: Symmetric Primitive for Shorter Signatures with Stronger Security

IACR Cryptology ePrint Archive, 2023
Post-quantum signature schemes based on the MPC-in-the-Head (MPCitH) paradigm are recently attracting significant attention as their security solely depends on the one-wayness of the underlying primitive, providing diversity for the hardness assumption ...

A Low Power Design for Sbox Cryptographic Primitive of Advanced Encryption Standard for Mobile End-Users

Journal of Low Power Electronics, 2007
Most known Sbox Advanced Encryption Standard implementations aim at minimizing chip covered area or achieving high throughput, and usually power consumption is a secondary metric of their cost.

Cryptographic Primitives And Quantum Theory [PDF]

Workshop on Physics and Computation, 2005
only using public key cryptography, but using quantum mechanics as a support. This paper summarizes the current knowledge in the field of two-party cryptographic protocols devised f rom quantum systems. W e introduce the reader to the notion of cryptographic protocols and describe a number of sample building blocks to achieve them.

A Study of Cryptographic Backdoors in Cryptographic Primitives

Electrical Engineering (ICEE), Iranian Conference on, 2018
Since the revelations of Edward Snowden in 2013, the topic of cryptographic backdoors has been popular in both cyber security and popular culture. However, such backdoors were well known in the cryptology community well before 2013. There are a variety of mechanisms for modifying cryptographic primitives so that the resultant modified algorithm is more

Physically Unclonable Cryptographic Primitives by Chemical Vapor Deposition of Layered MoS2.

ACS Nano, 2017
Physically unclonable cryptographic primitives are promising for securing the rapidly growing number of electronic devices. Here, we introduce physically unclonable primitives from layered molybdenum disulfide (MoS2) by leveraging the natural randomness ...

Making Cryptographic Primitives Harder

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2008
This paper studies a method for transforming ordinary cryptographic primitives to new harder primitives. Such a method is expected to lead to general schemes that make present cryptosystems secure against the attack of quantum computers. We propose a general technique to construct a new function from an ordinary primitive function f with a help of ...

Random Organic Nanolaser Arrays for Cryptographic Primitives

Advanced Materials, 2019
AbstractNext‐generation high‐security cryptography and communication call for nondeterministic generation and efficient authentication of unclonable bit sequences. Physical unclonable functions using inherent randomness in material and device fabrication process have emerged as promising candidates for realizing one‐way cryptographic systems that avoid

Implementing Cryptographic Primitives in the Symbolic Model [PDF]

, 2011
When discussing protocol properties in the symbolic (Dolev-Yao; term-based) model of cryptography, the set of cryptographic primitives is defined by the constructors of the term algebra and by the equational theory on top of it. The set of considered primitives is not easily modifiable during the discussion.
