Sticky Advance Overflow (SAV) & Block Scaling in FFT The Sticky Advance Overflow (SAV) bit, which is set whenever an overflow "almost" occurred, can be used in block scaling of intermediate results during an FFT (Fast Fourier Transformation) calculation. Before each pass of applying a butter...

On the 8-bit platform (i.e. AVR), their implementation of the Fast Fourier Transform (FFT) needs 755 k and 2.2 M cycles for medium and long-term security, respectively. Thanks to the efficiency of the polynomial multiplication and the Gaussian sampler function, their LWE-based encryption ...
