Transferencia
de claves entre módulos criptográficos. Típicamente la transferencia se realiza
cifrada.
1. (I) A key establishment
method by which a secret key is generated by a system entity in a communication
association and securely sent to another entity in the association. (Compare:
key agreement.)
2. (O) "The procedure
to send a symmetric key from one party to other parties. As a result, all
legitimate participants share a common symmetric key in such a way that the
symmetric key is determined entirely by one party." [A9042]
[RFC4949:2007]
A key establishment
procedure whereby one party (the sender) selects and encrypts the keying
material and then distributes the material to another party (the receiver).
When used in conjunction
with a public key (asymmetric) algorithm, the keying material is encrypted
using the public key of the receiver and subsequently decrypted using the
private key of the receiver. When used in conjunction with a symmetric
algorithm, the keying material is wrapped with a key encrypting key shared by
the two parties.
[NIST-SP800-57:2007]
the process of transferring
a key from one entity to another entity. [ISO-19790:2006]
the transfer of
cryptographic keys, usually in encrypted form, using electronic means such as a
computer network. [ISO-19790:2006]
secure transport of
cryptographic keys from one cryptographic module to another module. [FIPS-140-2:2001]
