KYK-13

KYK-13 on display at the National Cryptologic Museum.

The KYK-13 Electronic Transfer Device is a common fill device designed by the United States National Security Agency for the transfer and loading of cryptographic keys with their corresponding check word. The KYK-13 is battery powered and uses the DS-102 protocol for key transfer. Its National Stock Number is 5810-01-026-9618.

Even though the KYK-13 was first introduced in 1976 and was supposed to have been made obsolete by the AN/CYZ-10 Data Transfer Device, it is still widely used because of its simplicity and reliability.[1] A simpler device than the CYZ-10, the KIK-30 "Really Simple Key Loader" (RASKL) is now planned to replace the KYK-13, with up to $200 million budgeted to procure them in quantity.[2][3]
