The Pohlig-Hellman algorithm, published in 1978 by Stephen Pohlig and Martin Hellman [1], demonstrates that the discrete logarithm problem (DLP) becomes significantly easier when the group order has ...

Given the large volumes of sensitive information transmitted over the Internet, digital signatures are essential for verifying message authenticity and integrity. A key challenge is minimizing ...

A basic feature of number theory, prime numbers are also a fundamental building block of computer science, from hashtables to cryptography. Everyone knows that a prime number is one that cannot be ...

Number theory, the study of integers and their properties, has been a fundamental branch of mathematics for centuries. What many may not realize is that number theory plays a crucial role in the field ...

Prime numbers have fascinated mathematicians for centuries. These unique numbers can only be divided evenly by themselves and one, making them the building blocks of the world of mathematics. This ...

Abstract: We analyze the security of RSA prime generation implemented on embedded devices by a practical power analysis attack. Unlike previous differential power analysis-based attack on primality ...
