1993: Clinton administration proposed "Clipper Chip" method

From Wikipedia: The Clipper Chip was a chipset that was developed as an encryption device that secured “voice and data messages," with a built-in backdoor. It was intended to be adopted by telecommunications companies for voice transmission. It could not only encode messages but decode them as well. It was part of a Clinton Administration program to “allow Federal, State, and local law enforcement officials the ability to decode intercepted voice and data transmissions." Each clipper chip had] a unique serial number and a secret ‘unit key,’ programmed into the chip when manufactured."[2] This way, each device was meant to be different from the next. It was announced in 1993 and by 1996 was entirely defunct.

On This Day In History


  • Birthday of cryptologic machine designer Edward Hebern. Hebern's five-rotor cipher machine is cryptologically significant as part of the overall evolution in U.S. manufactured rotor devices. The National Cryptologic Museum has two very rare five-rotor Hebern cipher machines in its collection.

About Us

The NCMF directly supports the National Cryptologic Museum (NCM), the first public museum in the U.S. Intelligence Community. We think you will agree it is truly a "museum like no other."

Located adjacent to the National Security Agency (NSA) in Maryland, the NCM houses a priceless collection of artifacts that represent our Nation's history in code making and code breaking, as well as a world class library of cryptologic media. The NCMF acquires the best artifacts for the NCM and supports new educational and interactive exhibits.

The NCMF provides exceptional cryptologic programs throughout the year, encourages young minds to explore cryptology and innovation through valued awards, and hosts educational, cryptology-related exhibits at various community events.

As part of the Foundation's partnership with NSA to build the Cyber Center for Education and Innovation - Home of the National Cryptologic Museum (CCEI-NCM), the NCMF also serves as a leader in the field of cybersecurity - striving to provide the best in educational resources and programs.

The NCMF and NCM share a joint three-fold mission to Educate, Stimulate, and Commemorate. Learn more about our MISSION.
