MILSTAR satellites over a broad range of data rates. It fully accommodates all complex handshaking and resynchronization durations encountered during normal TDMA system operations. The KIV-7M fully implements all U. National Kiv 7 crypto Agency requirements for Type 1 certification, and is approved for use at the highest level of assurance.
These algorithms provide interoperability in coalition environments, and algorithm agility and reprogrammability for future security enhancements. Link Encryptor Family Interoperability Specification, and is fully compatible with previous versions of the KIV-7 family. Its innovative multi-channel design allows KIV-7M users to replace two legacy devices with one KIV-7M, thus recovering valuable space in fixed shelter environments and reducing weight for mobile applications. This upgradeability and backward compatibility allows the community of users to conduct a phased migration to the Global Information Grid without losing connectivity to legacy architectures.

Cisco 3600: RTS tied to DCD prevents DTR pulse. Cisco 3600: If DTR pulse is turned on NM-4T RTS goes full low correspondingly.
This section describes the cables necessary to connect the KG-194 and KIV-19, using the Pulse Engineering Cryptographic Equipment Enclosure, to the Cisco serial interfaces previously mentioned in this document. Platforms using the PA-4T, WIC-1T, and WIC-2T did not appear to be affected during testing. The DTR control signal is used to resync, or “prep” a crypto unit after synchronization is lost. The pulse-time x command must be entered in the serial interface configuration, or the crypto unit has no way to know the data that is received by the router is corrupt. The problem encountered on the Cisco 75xx platform is when a circuit disruption or crypto resync takes place.
The configured pulse-time x command caused DTR to transition only once, therefore the resynchronization of the external encryption gear could not take place. 36xx platforms is when a circuit disruption or crypto resync takes place. The configured pulse-time x command caused RTS to glitch every 1. 5 ms, as seen with a digital oscilloscope. This occurred until the pulse-time x command was taken out of the serial interface configuration. This glitch is detrimental because the cabling scheme calls for the control signals to be tied together.
This results in continuous interface resets. Background The military has a need for secure communications. These fall into two general catagories: Voice and Data. The method of encryption depends on the channel used. For VHF voice communications the VINSON comsec system has been in place for a number of years. KYV-2 and -2A were designed to implement VINSON on the PRC-68 series squad radios. The system also is known as SAVILLE.
The KY-57 sends a synchronization header at the start of each transmission. The radio operator should hear beeps when the crypto box syncs. There is no provision to hear a clear transmission when the SVM is installed on a radio. SVM is installed the only way is if the transmission is encrypted. When the SVM was developed the PRC-68 and PRC-68A were in service.
