  "definition": "1. A bit string such that non-overlapping segments of the string (with the required lengths) can be used as cryptographic keys or other secret (pseudorandom) parameters.\n\n2. Data that is represented as a binary string such that any non-overlapping segments of the string with the required lengths can be used as secret keys, secret initialization vectors, and other secret parameters.\n\n3. The data (e.g., keys) necessary to establish and maintain cryptographic keying relationships.\n\n4. A bit string such that any non-overlapping, contiguous segments of the string with required lengths can be used as secret keys, secret initialization vectors, and other secret parameters.\n\n5. Key, code, or authentication information in physical, electronic, or magnetic form. It includes key tapes and list, codes, authenticators, one-time pads, floppy disks, and magnetic tapes containing keys, plugs, keyed microcircuits, electronically generated key, etc.\n\n6. A bit string, such that any non-overlapping segments of the string with the required lengths can be used as symmetric cryptographic keys and secret parameters, such as initialization vectors.\n\n7. A binary string, such that any non-overlapping segments of the string with the required lengths can be used as symmetric cryptographic keys.\n\n8. Data that is represented as a binary string such that any non-overlapping segments of the string with the required lengths can be used as symmetric cryptographic keys. In this Recommendation, keying material is derived from a shared secret established during an execution of a key-establishment scheme or generated by the sender in a key-transport scheme. As used in this Recommendation, secret keying material may include keys, secret initialization vectors, and other secret parameters.\n\n9. A binary string, such that any non-overlapping segments of the string with the required lengths can be used as symmetric cryptographic keys and secret parameters, such as initialization vectors.\n\n10. The data (e.g., keys and IVs) necessary to establish and maintain cryptographic keying relationships.\n\n11. Data that is represented as a binary string such that any non-overlapping segments of the string with the required lengths can be used as secret keys, secret initialization vectors and other secret parameters.\n\n12. A cryptographic key and other parameters (e.g., IVs or domain parameters) used with a cryptographic algorithm.\n\n13. A cryptographic key and other parameters (e.g., IVs or domain parameters) used with a cryptographic algorithm. When keying material is derived as specified in SP 800-56CSP 800-108:bit string such that any non-overlapping segments of the string with the required lengths 4 and 5 Data represented as a can be used as secret keys, secret initialization vectors, and other secret parameters.\n\n14. Data that is represented as a binary string such that any non-overlapping segments of the string with the required lengths can be used as symmetric cryptographic keys. In this Recommendation, keying material is derived from a shared secret established during an execution of a key-agreement scheme, or transported by the sender in a key-transport scheme. As used in this Recommendation, secret keying material may include keys, secret initialization vectors, and other secret parameters.",
