IBM’s quantum computer cracked a 6-bit ECC key—safe for now, but experts warn Bitcoin and Ethereum must prepare for quantum threats.

SK Telecom announced that it has launched a 'QKD-PQC hybrid quantum cryptography' product that combines the latest PQC (Post Quantum Cryptography) standard algorithm and QKD (Quantum Key Distribution) ...

I welcomed the New Year by playing mahjong with my family. The version we play starts with one person rolling three dice and then counting around the table of four players to whatever the total is.

Add a description, image, and links to the modular-arithmetic topic page so that developers can more easily learn about it.

From basic algorithms like Sieve, Bitwise-sieve, Segmnted-sieve, Modular Arithmetic, Big Mod to Primality test, CRT etc. all other advance number theory algorithms.

Abstract: This paper analyzes the reconfigurable design principles of public-key cryptography and the characteristics of modular arithmetic iteration process. According to the analysis results, a ...
