A '''HAIPE (High Assurance Internet Protocol Encryptor)''' is a [[Type 1 encryption]] device that complies with the [[National Security Agency]]'s HAIPE IS (formerly the HAIPIS, the High Assurance Internet Protocol Interoperability Specification). The [[cryptography]] used is [[NSA Suite A Cryptography|Suite A]] and [[NSA Suite B|Suite B]], also specified by the NSA as part of the [[Cryptographic Modernization Program]]. HAIPE IS is based on [[IPsec]] with additional restrictions and enhancements. One of these enhancements includes the ability to encrypt [[multicasting|multicast]] data using a "preplaced key" (see definition in [[List of cryptographic key types]]). This requires loading the same key on all HAIPE devices that will participate in the multicast session in advance of data transmission. A HAIPE is typically a secure gateway that allows two enclaves to exchange data over an untrusted or lower-classification network.
