## Abstract:

A transform analogous to the discrete Fourier transform may be defined in a finite field, and may be calculated efficiently by the ’fast Fourier transform’ algorithm. The transform may be applied to the problem of calculating convolutions of long integer sequences by means of integer arithmetic.## References
