Implementation of the eXtended Naor-Yung Signature Scheme. It was specifically designed for use in blockchain technologies.
XNYSS uses a modified form of Naor-Yung chaining to transform a One-Time Signature (OTS) scheme into a many-time scheme. This is achieved by including the hashes of two public keys, to be used for future signatures, in every created signature. Thus every signature in the resulting binary tree can be traced back to the first one.
This implementation is part of my master's thesis, which can be found here.
