FASCINATOR is a digital voice encryption standard for the Federal Government. It is based on voice being digitized using 12 kbit/s Continuously Variable Slope Delta modulation (CVSD) and then encrypted using a National Security Agency (NSA) Commercial COMSEC Endorsement Program (CCEP) Type I encryption algorithm.
FED-STD-1023 Governs the design and interoperability requirements for Facinator.
Fascinator is used on a 25 KHz channel above 30 MHz.
Encryption of the digitized voice shall be accomplished with the encryption algorithm used in the INDICTOR and WINDSTER COMSEC Modules using the cryptographic mode that has cryptographic compatibility with the KY-57/58.
Fascinator encryption modules are considered Controlled Cryptographic Items (CCI).
