Overview Edit

The Escrowed Encryption Standard (EES) is a voluntary alternative to the original federal encryption standard used to safeguard unclassified information, the Data Encryption Standard (DES). A key-escrowing scheme is built in to ensure lawfully authorized electronic surveillance when key-escrow encryption is used.

The EES was intended for use in safeguarding voice, facsimile, or computer data communicated in a telephone system. The Clipper chip was designed for use in telephone systems; it contains the EES encryption algorithm, called SKIPJACK.
