Description/Abstract:: Programs for solving univariate and multivariate polynomials. load "Univariate"; will load a collection of routines for polynomials in one variable. The file main_univariate shows how to call the different routines. load "solve_overdetermined.txt"; will generate an overdetermined system and the uses the relinearization method to solve it. Delete the first part of the program in order to run it with your own system of equations.

Description/Abstract:: Magma programs for the original method of Matsumoto-Imai. Download the files and then in Magma use load "keygen.txt"; load "encrypt.txt"; load "decrypt.txt"; The first program will generate the files private_key.txt and public_key.txt. With load "LinearizationEquations.txt";. the equations are produced to break this method. Experiment by changing the parameters.

Description/Abstract:: Magma programs to chapter 5 of the book "Multivariate Public Key Cryptosystems" by Ding, Petzoldt and Schmidt. For the rainbow cryptosystems load "keygen.txt'; will generate the files public_key.txt and private_key.txt, which are then used via load "sign.txt"; to genertate the signature of a randomly generated document, and by load "verify.txt"; to chack that it is a valid signature

Description/Abstract:: Programs used and described in the book "Multivariate Public Key Cryptosystems" by Ding, Petzoldt and Schmidt. All programs can be downloaded via the attached zip file. Modify the file "startup.txt" so that the base directory matches your setup. Put this file where magma can find it. After starting magma run: load "startup.txt"; It will then allow you to select the method on which you want to work. Files can be downloaded individually by clicking on a chapter name and then selecting the scheme of interest.
