Mykotronx: "Rainbow was responsible for developing and supporting top secret encryption devices used by the NSA, NRO and other government agencies [2]. In 2004, Rainbow Technologies was acquired by SafeNet and went on as SafeNet Government Solutions, LLC, providing INFOSEC and COMSEC products for the US government [3]. Nevertheless, the KIV-7 COMSEC products were still sold under the Mykotronx brand, just like the Fortezza Crypto Cards."
