Implementation of the attacks on the bm-fssagg and ar-fssagg signature schemes

Abstract: This publication contains the implementation of the attacks on the BM-FssAgg and AR-FssAgg cryptographic signature schemes. These attacks were published and presented at the Financial Cryptography Conference 2017. TechnicalRemarks: The implementation is written for the computer algebra System SageMath. It was developed with SageMath version 6.7.

The code can be configured by editing the variables at the start of the file. To run the code, simply execute the file with the SageMath interpreter.
