| (I) A set of mathematically related keys--a public key and a
private key--that are used for asymmetric cryptography and are
generated in a way that makes it computationally infeasible to
derive the private key from knowledge of the public key (e.g.,
see: Diffie-Hellman, Rivest-Shamir-Adleman).
(C) A key pair's owner discloses the public key to other system
entities so they can use the key to encrypt data, verify a digital
signature, compute a protected checksum, or generate a key in a
key agreement algorithm. The matching private key is kept secret
by the owner, who uses it to decrypt data, generate a digital
signature, verify a protected checksum, or generate a key in a key
agreement algorithm.
