New algorithm shakes up cryptography Date: May 15, 2014 Source: CNRS Summary: Researchers have solved one aspect of the discrete logarithm problem. This is considered to be one of the 'holy grails ...

The discrete Fourier-cosine transform (cos-DFT), the discrete Fourier-sine transform (sin-DFT) and the discrete cosine transform (DCT) are closely related to the discrete Fourier transform (DFT) of ...

This paper considers factoring integers and finding discrete logarithms, two problems that are generally thought to be hard on classical computers and that have been used as the basis of several ...
