ZK-Crypt
In cryptography, ZK-Crypt is a stream cipher developed by Carmi Gressel, Ran Granot, and Gabi Vago and has been patented. It has been submitted to the eSTREAM Project of the eCRYPT network, but has been dropped in Phase II due to the lack of documentation and limited independent security analysis.
