Encyclopedia > Type 1 encryption

In cryptography, a Type 1 product is a device or system certified by the National Security Agency (NSA) for use in cryptographically securing classified U.S. Government information.


Type 1 certification is a rigorous process that includes testing and formal analysis of (among other things) cryptographic security, functional security, tamper resistance (QUADRANT), emissions security (EMSEC/TEMPEST), and security of the product manufacturing and distribution process.


For a historically-oriented list of NSA encryption products (most of them Type 1), see NSA encryption systems. For algorithms that NSA has participated in the development of, see NSA encryption algorithms.

RFC 2946 (rfc2946) - Telnet Data Encryption Option (1964 words)
It is used by various encryption mechanisms to identify which encryption key is to be used, when multiple encryption keys might be known on either side of the connection.
The order of the encryption types in a SUPPORT command must be ordered to indicate a preference for different encryption types, the first type being the most preferred, and the last type the least preferred.
If encryption is requested by the user, and the client is unable to negotiate enabling or re-enabling encryption, the client must assume that it is being attacked, and MUST immediately terminate the telnet connection.
