SkipJack cryptography
An encryption algorithm created by the NSA (National Security Agency) which encrypts 64-bit blocks of data with an 80-bit key. It is used in the Clipper chip, a VLSI device with an ARM processor core, which is intended to perform cryptographic operations while allowing the security agencies listen in.
