Cryptographic information is used with a given cryptographic mechanism (e.g., digital signatures or a key establishment scheme) or with a particular application. Protection shall be provided to ensure that the information is not used incorrectly (e.g., not only must the usage or application be associated with the keying material, but the integrity of this association must be maintained). This protection can be provided by separating the cryptographic information from that of other mechanisms or applications, or by the use of appropriate metadata associated with the information. Section 6.2.3 addresses the metadata associated with cryptographic information.
