KIV-78 — Mode 4/Mode 5 IFF Crypto Appliqué

Identification Friend or Foe Crypto Solutions Supporting the Customer’s Needs

• Appliqué form-factor supports easy removal and storage without host impact
• Mark XIIA (Mode 4 and Mode 5)
• AIMS 04-900 compliant, NSA certified
• Simultaneous Mode 4/5 interrogate and transpond support
• Software upgradeable

As a leading supplier of cryptography for avionics systems, General Dynamics C4 Systems has over 40 years of Type 1 system development experience. Our avionics systems include some of the most advanced hardware, software and mechanical designs, integrated to meet the community’s high standards for security, in lightweight, low-power, ruggedized form factors.

The General Dynamics KIV-78 provides cryptographic and time-of-day services for a Mark XIIA (Mode 4 and Mode 5) IFF Combined Interrogator/Transponder (CIT), individual interrogator, individual transponder or IFF system deployed to identify cooperative, friendly systems.

The General Dynamics KIV-78 is capable of concurrent Mode 4/Mode 5 operations as well as concurrent interrogator/transponder operations. It performs black key management supporting up to three months’ worth of keys for Mode 4 and Mode 5 IFF and stores these keys in encrypted format, allowing black key recovery.

General Dynamics’ KIV-78 is capable of both battery powered (Cold Load) and prime powered (Warm Load) key loading via DS-101. KIV-78 is compatible with both the CYZ-10, PYQ-10, KIK-20 and other EKMS308/608 compliant DS-101 key load devices. Other functions KIV-78 provides for the IFF system include time-of-day services, status reporting, and host key management services. The KIV-78 interface is specified in the Department of Defense AIM 04-900 document and is NSA-certified.

IFF Crypto Support Tools

Emulator: Performs Mode 4 and Mode 5 interrogate and transpond functions that are compliant to 04-900 Option A with respect to interface voltages, waveforms and timing. However, this emulation does not use actual cryptography, and therefore is not a CCI device.

STE: Performs closed box confidence testing on KIV-78 and emulator to verify unit is functional. The STE can also be used to collect crypto status, verify QKEK, check for low battery, and confirm which image versions are loaded.

Why General Dynamics?

Designing any system is difficult, but given the gravity of IFF-based decisions, disciplined system design is even more critical. Our background and experience in cryptographic designs, paired with our strong design processes, result in low-risk, highly reliable systems.

At General Dynamics C4 Systems, we build IFF crypto solutions for every branch of the military. Our IFF crypto solutions provide legacy interoperability and the programmability to adapt to new cryptographic protocols without hardware modification. With 40 years of overall cryptographic experience and 15 years building IFF systems, General Dynamics C4 Systems has the proven ability to secure IFF systems.
