KY-68
Encyclopedia : K : KY : KY6 : KY-68
The TSEC/KY-68 is a ruggedized telephone terminal with a built-in encryption/decryption module for secure traffic. It can be used in the field. It is a full-duplex voice and data interface terminal that converts voice to digital form, encrypts it and transmits at 16 or 32 kbit/s. The KY-68 can operate via civilian and military switches. Although used primarily for secure communications, the KY-68 can operate with a Digital Non-secure Voice Terminal - a DNVT as its partner. The local switch provides the KY-68 user with a warning tone when communicating with a nonsecure terminal; however, the tone stops as soon as the DNVT user picks up the handset. For data communications, the KY-68 is equipped with a data port for encryption with various data devices.
The key is inserted into the KY-68 using a KYK-13 keying device.
The office version of the KY-68 is the KY-78. It is made from lighter materials, but has the same insides as the KY-68.
The KY-68 and KY-78 are approved at the SECRET level.
The KY-78 was compromised in the early 1990's, but it and the KY-68 are still in use.
