Description

This package provides a symbolic representation of Linear Feedback Shift Registers, often used in cryptography. With this package, you can generate bit sequeneces from LFSRs, and from bit sequences determine the minimal generating LFSR along with the linear complexity profile using the Berlekamp-Massey algorithm.

New to version 2.0 is implementation that is 10x faster than previous ones for computing the linear complexity.

In particular the guide and examples are at http://modp.com/release/mma_lfsr.
