A key derivation function is used to derive the different keys used in a crypto context (SRTP and SRTCP encryption keys and salts, SRTP and SRTCP authentication keys) from one single master key in a cryptographically secure way. Thus, the key management protocol needs to exchange only one master key, all the necessary session keys are generated ...
It supports packet recovery while maintaining low latency (default: 120 ms). SRT also supports encryption using AES. The protocol was derived from the UDT project, [2] which was designed for fast file transmission. It provided the reliability mechanism by utilizing similar methods for connection, sequence numbers, acknowledgements and re ...
Per CNSSP-15, the 256-bit elliptic curve (specified in FIPS 186-2), SHA-256, and AES with 128-bit keys are sufficient for protecting classified information up to the Secret level, while the 384-bit elliptic curve (specified in FIPS 186-2), SHA-384, and AES with 256-bit keys are necessary for the protection of Top Secret information.

As of October 2012, CNSSP-15 [4] stated that the 256-bit elliptic curve (specified in FIPS 186-2), SHA-256, and AES with 128-bit keys are sufficient for protecting classified information up to the Secret level, while the 384-bit elliptic curve (specified in FIPS 186-2), SHA-384, and AES with 256-bit keys are necessary for the protection of Top ...
A High Assurance Internet Protocol Encryptor (HAIPE) 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).

ChaCha20-Poly1305 usually offers better performance than the more prevalent AES-GCM algorithm, except on systems where the CPU(s) have the AES-NI instruction set extension [1]. As a result, ChaCha20-Poly1305 is sometimes preferred over AES-GCM due to its similar levels of security and in certain use cases involving mobile devices , which mostly ...
