A Bit Commitment Scheme Based on Diophantine Approximation
In Using the Inhomogenous Simultaneous Diophantine Approximation Problem for Cryptographic Design, Frederik Armknecht, Carsten Elsner and me constructed a bit commitment scheme based on the above-named problem from analytic number theory.
An object oriented C++ implementation of the bit commitment scheme can be downloaded here. For the arbitrary precision arithmetic used in the scheme, you need the GNU Multiple Precision Arithmetic Library and the The GNU MPFR Library (maybe you have to adapt the Makefile according to your library installations).
If you find any bugs or if you think that something can be handled in a smarter way than I did, please let me now (email@example.com).
