21.11.2009 More secure than AES – mode FMC

Saturday, November 21st, 2009

Since I am planning a project which relies on storing encrypted information on a potentially hostile host, I tried to design a cryptographic mode, called mode FMC. This mode should, when combined with AES, provide a higher security margin than AES alone would. Basically mode FMC is a try to defend your private data (like credit card numbers or password lists stored in the application I am going to write) against yet to be discovered weaknesses in AES. As with any cryptographic project, it would be great to get review.
I’ve written a paper and published the code under LGPL. The code is implemented in C++ and includes a python binding.
