  "id": "MLC-T-CYB-002331",
  "term": "key establishment",
  "field": "Cybersecurity",
  "definition": "1. A procedure conducted by two or more participants, after which the resultant keying material is shared by all participants.\n\n2. The procedure that results in keying material that is shared among different parties.\n\n3. A procedure that results in secret keying material that is shared among different parties.\n\n4. A procedure that results in secret keying material that is shared among different parties. Key agreement, using a KEM, and key transport are all types of key establishment.\n\n5. A function in the lifecycle of keying material; the process by which cryptographic keys are securely established among cryptographic modules using manual transport methods (e.g., key loaders), automated methods (e.g., key-transport and/or key-agreement protocols), or a combination of automated and manual methods (consists of key transport plus key agreement).\n\n6. A procedure, conducted by two or more participants, after which the resultant keying material is shared by all participants.\n\n7. The process that results in the sharing of a key between two or more entities, either by transporting a key from one entity to another (key transport) or generating a key from information shared by the entities (key agreement).\n\n8. A procedure that results in generating shared keying material among different parties.\n\n9. A procedure that results in establishing secret keying material that is shared among different parties.\n\n10. The process that results in the sharing of a key between two or more entities, either by manual distribution, using automated key transport or key agreement mechanisms or by using key derivation that employs an already-shared key between or among those entities. Key establishment may include the creation of a key.\n\n11. A function in the lifecycle of keying material; the process by which cryptographic keys are securely established among cryptographic modules using manual transport methods (e.g., key loaders), automated methods (e.g., key-transport and/or key-agreement protocols), or a combination of automated and manual methods.\n\n12. A stage in the lifecycle of keying material; the process by which cryptographic keys are securely distributed among cryptographic modules using manual transport methods (e.g., key loaders), automated methods (e.g., key transport and/or key agreement protocols), or a combination of automated and manual methods (consists of key transport plus key agreement).\n\n13. The procedure that results in keying material that is shared among different entities.\n\n14. A function in the lifecycle of a cryptographic key; the process by which cryptographic keys are securely established among entities using manual transport methods (e.g., key loaders), automated methods (e.g., key-transport and/or key-agreement protocols), or a combination of automated and manual methods.\n\n15. The procedure that results in keying material that is shared between the participating parties in a key-establishment transaction.",
