RSA cryptography, which is one of the typical public key cryptosystems, is a cryptosystem based on the fact that it is difficult to factor a composite number with a large number of digits into prime ...

Abstract: RSA is a significant cryptographic technique depending on public key cryptography. In fact, if this technique does not have any vulnerabilities, it is considered as a robust algorithm.

Abstract: Compared with traditional Fast Fourier Transform (FFT), modulation FFT preserves its characteristics of low complexity when used to estimate the frequencies of real-valued signals. But there ...

Prime numbers are all the rage these days. I can tell something’s up when random people start asking me about the randomness of primes—without even knowing that I’m a mathematician! In the past couple ...

The implemented template class recursion has P levels. Every FFT calculation process runs from level P to level 1, while the level 1 is empty (Listing Three, in part one of this article). Some ...
