Triple

Target class: cryptographic key-agreement protocol
Context triple: [ZRTP, instanceOf, cryptographic key-agreement protocol]

• A. cryptographic protocol chosen
  A cryptographic protocol is a precisely defined sequence of operations and message exchanges that uses cryptographic primitives to achieve security goals such as confidentiality, integrity, authentication, and non-repudiation between parties.
• B. cryptographic protocol framework
  A cryptographic protocol framework is a structured set of tools, abstractions, and rules that enables the design, specification, analysis, and implementation of secure communication protocols.
• C. cryptographic protocol message
  A cryptographic protocol message is a structured unit of data exchanged between parties in a cryptographic protocol, containing information such as identifiers, nonces, keys, and signatures to achieve security goals like confidentiality, integrity, and authentication.
• D. cryptographic key
  A cryptographic key is a piece of information, usually a string of bits, used by cryptographic algorithms to encrypt, decrypt, sign, or verify data securely.
• E. cryptographic primitive
  A cryptographic primitive is a low-level, well-defined algorithm or protocol (such as a hash function, block cipher, or digital signature scheme) that serves as a basic building block for constructing more complex cryptographic systems and protocols.
• F. None of above.
