    Document thumbnail: MI (original Matsumoto-Imai method)
    Type:
    Document
    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.

    Document
    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.
