AN/PYQ-10
From Wikipedia, the free encyclopedia
The AN/PYQ-10 Simple Key Loader (SKL) is a portable, hand-held fill device, for securely receiving, storing, and transferring data between compatible cryptographic and communications equipment. Developed by SAIC under the auspices of the United States Army and the National Security Agency, it is intended to supplement and eventually replace the AN/CYZ-10 Data Transfer Device (DTD). The PYQ-10 provides all the functions currently resident in the CYZ-10 and incorporates new features that provide streamlined management of COMSEC key, Electronic Protection (EP) data, and Signal Operating Instructions (SOI). The SKL is backward-compatible with existing End Cryptographic Units (ECU) and forward-compatible with future security equipment and systems.
Something to note with the SKL is that it uses a Windows based platform. It is similar to a Tablet PC in the way that it uses a small plastic stylus to move the mouse around the screen and perform the 'click' action. This is viewed commonly by the Air Force as the weakest design flaw of the SKL. These stylus often break after 50 to 100 flights rendering the device unusable until more can be ordered. Another issue with the SKL is that they tend to dump the database for no apparent reason and must often be reloaded from another SKL or rebuilt manualy.
