  "term": "key pair",
  "field": "Cybersecurity",
  "definition": "1. A set of two keys with the property that one key can be made public while the other key must be kept private. In this standard, this could refer to either the (encapsulation key, decapsulation key) key pair of a KEM or the (encryption key, decryption key) key pair of a PKE.\n\n2. A public key and its corresponding private key.\n\n3. A set of two keys with the property that one key can be made public, while the other key must be kept private. In this publication, this could refer to either the (encapsulation key, decapsulation key) key pair of a KEM or the (encryption key, decryption key) key pair of a public-key encryption (PKE) scheme.\n\n4. A public key and its corresponding private key; a key pair is used with a public key algorithm.\n\n5. A private key and its corresponding public key; a key pair is used with an asymmetric-key (public-key) algorithm.\n\n6. Two mathematically related keys having the properties that (1) one key can be used to encrypt a message that can only be decrypted using the other key, and (ii) even knowing one key, it is computationally infeasible to discover the other key.\n\n7. A public key and its corresponding private key; a key pair is used with a public-key algorithm.\n\n8. See key-establishment key pair.\n\n9. A public key and its corresponding private key. A key pair is used with a public key algorithm.\n\n10. A public key and its corresponding private key; a key pair is used with a public-key (asymmetric-key) algorithm.",
