Key management | National Security Agency encryption devices
The KSD-64[A] Crypto Ignition Key (CIK) is an NSA-developed EEPROM chip packed in a plastic case that looks like a toy key. The model number is due to its storage capacity — 64 kibibits (65,536 bits, or 8 KiB), enough to store multiple encryption keys. Most frequently it was used in key-splitting applications: either the encryption device or the KSD-64 alone is worthless, but together they can be used to make encrypted connections. It was also used alone as a fill device for transfer of key material, as for the initial seed key loading of an STU-III secure phone. Newer systems, such as the Secure Terminal Equipment, use the Fortezza PC card as a security token instead of the KSD-64. The KSD-64 was withdrawn from the market in 2014. Over one million were produced in its 30-year life. (Wikipedia).
