Demonstration of Grover’s algorithm for retrieving secret keys in a basic SPN block cipher

CTU Journal of Innovation and Sustainable Development
In this study, we present in detail the application of Grover's quantum algorithm to the searching problem of the secret key of a simple SPN (Substitution–permutation network) block cipher called Yo-yo.

Free-Space Quantum Key Distribution

, 2016
Based on the firm laws of physics rather than unproven foundations of mathematical complexity, quantum cryptography provides a radically different solution for encryption and promises unconditional security.

Kleptography: Using Cryptography Against Cryptography [PDF]

, 1997
The notion of a Secretly Embedded Trapdoor with Universal Protection (SETUP) has been recently introduced. In this paper we extend the study of stealing information securely and subliminally from black-box cryptosystems. The SETUP mechanisms presented here, in contrast with previous ones, leak secret key information without using an explicit subliminal

Cryptography: Mathematical Advancements on Cyber Security [PDF]

, 2019
The origin of cryptography, the study of encoding and decoding messages, dates back to ancient times around 1900 BC. The ancient Egyptians enlisted the use of basic encryption techniques to conceal personal information.
