Hi there, I have uploaded the constructor to http://sage.math.washington.edu/home/malb/sr/ . You will have to attach both files. sr.py contains the Small Scale AES variants constructor and mpolynomialsystem.py a class to deal with multivariate polynomial systems. I am not that satisfied with either of them. I think MPolynomialSystem will change a lot in the future and feedback/input is very welcome. The idea is to have a class to deal conveniently with sets/lists of polynomials with a common solution. In some other CASes this would be called an ideal but SAGE makes the mathematically correct distinction between ideals and the set of generators. So, let me know what you think about it. About the SymbolicData export: Wouldn't it be better to have a symbolic_data method on either Ideal and/or MPolynomialSystem to export the set of generators to the SymbolicData format instead of writing a custom one for all the cryptosystems? Btw: Michael Brickenstein (of SINGULAR) also worked with the SymbolicData format and recommended including lxml to SAGE for that reason.
