KG-135 (TACTICAL HIGH SPEED KEY GENERATOR)

The KG-135 is a tactical, high-speed, half duplex, self-synchronizing serial data link key generator. It is designed for use in an uninhabited airborne environment at altitudes up to 100,000 feet and satisfies Tactical Rad-Hard specifications. The KG-135 is a "Load and Go" unit, which means it can start
encrypting or decrypting, assuming a good checkword/key (CW/Key), when power is applied. The KG-135 has an external computer bus connection, key management interface, power supply, and appropriate TEMPEST filtering. It operates at speeds of 10 Mbps to 450 Mbps.

The KG-135 accepts standard paper tape key via KOI-18 or KYK-13. A maximum of six keys and associated checkwords may be loaded and stored directly into the Key Management portion of the KG-135 for retrieval. The KG-135 allows for key loading without using the Command Status port. Only one key may be used in this scenario. The external computer bus interface allows for status monitoring and transfer of stored CW/key into the KG-135 cryptologics. Key Management hardware automatically restarts the unit, reloads the last key in use, and resynchronizes on the re-application of power.

The KG-135 serves as an encryptor/decryptor for wide-band serial communications. It is approved for use at all classification levels. The authorized vendor is Motorola, Inc. The cost is estimated in the range of $100,000 to $200,000.
