(En un
critposistema de claves públicas) clave de un par de claves de usuario que es
conocida públicamente. [X.509:2005]
En un
criptosistema asimétrico, clave criptográfica de un usuario que se hace de
público conocimiento (ISO/IEC 9594-2, ITU-T X.509). [Ribagorda:1997]
Clave que se
utiliza con un algoritmo criptográfico asimétrico y que puede estar disponible
públicamente. [X.810:1995]
A cryptographic
key that may be widely published and is used to enable the operation of an
asymmetric cryptography scheme. This key is mathematically linked with a
corresponding private key. Typically, a public key can be used to encrypt, but
not decrypt, or to validate a signature, but not to sign. [CNSSI_4009:2010]
1. (I) The
publicly disclosable component of a pair of cryptographic keys used for
asymmetric cryptography. (See: key pair. Compare: private key.)
2. (O) In a
public key cryptosystem, "that key of a user's key pair which is publicly
known." [X509]
[RFC4949:2007]
A cryptographic
key used with a public key cryptographic algorithm that is uniquely associated
with an entity and that may be made public.
In an asymmetric (public) cryptosystem, the public key is associated
with a private key. The public key may be known by anyone and, depending on the
algorithm, may be used to:
·
Verify
a digital signature that is signed by the corresponding private key,
·
Encrypt
data that can be decrypted by the corresponding private key, or
·
Compute
a piece of shared data.
[NIST-SP800-57:2007]
that key of an
entitys asymmetric key pair which can be made public [ISO/IEC
ISO-11770-1:1996]. [ISO-18033-1:2005]
(In a public key
cryptosystem) that key of a user's key pair which is publicly known.
[X.509:2005]
That data item,
key or number, of an asymmetric pair, that can be made public and shall be used
by every verifier for establishing the claimant's identity. [ISO-9798-5:2004]
that key of an
entity's asymmetric key pair which can be made public.
NOTE. In the case
of an asymmetric signature system the public key defines the verification
transformation. In the case of an asymmetric encipherment system the public key
defines the encipherment transformation. A key that is 'publicly known' is not
necessarily globally available. The key may only be available to all members of
a pre-specified group.
[ISO-11770-3:2008]
That key of an
entity's asymmetric key pair which can be made public.
NOTE. In the case
of an asymmetric signature system, the public key defines the verification
transformation. In the case of an asymmetric encipherment system the public key
defines the encipherment transformation. A key that is 'publicly known' is not
necessarily globally available. The key may only be available to all members of
a pre-specified group.
[ISO-9798-1:1997]
A key that is
used with an asymmetric cryptographic algorithm and that can be made publicly
available. [X.810:1995]
(dans un système de
chiffrement avec clé publique) celle des clés d'une paire de clés d'un
utilisateur qui est connue de manière publique. [X.509:2005]
Une des deux clés du
couple clé publique/clé privée rendue publique et connue par tous. Elle
intervient dans le mécanisme de chiffrement et permet de chiffrer
électroniquement des messages à l'intention du détenteur de cette clef, message
qui sera ensuite déchiffré par la clé privée. [ISO-9798-1:1997]
clé qui est utilisée
avec un algorithme asymétrique de cryptographie et qui peut être rendue
publique. [X.810:1995]
