Documento
electrónico que permite asociar una clave criptográfica pública a una entidad
propietaria de dicha clave, y que está protegido criptográficamente para
garantizar su integridad y su autenticidad. [CCN-STIC-430:2006]

Es la pieza
central de la infraestructura PKI, y es la estructura de datos que enlaza la
clave pública con los datos que permiten identificar al titular. Su sintaxis,
se define empleando el lenguaje ASN.1 (Abstract Syntax Notation One), y los
formatos de codificación más comunes son DER (Distinguish Encoding Rules) o PEM
(Privacy Enhanced Mail).

A digitally signed
representation of information that 1) identifies the authority issuing it, 2)
identifies the subscriber, 3) identifies its valid operational period (date
issued / expiration date). In the IA community certificate usually implies
public key certificate and can have the following types:
cross certificate – A
certificate issued from a CA that signs the public key of another CA not within
its trust hierarchy that establishes a trust relationship between the two CAs.
encryption certificate – A
certificate containing a public key that can encrypt or decrypt electronic
messages, files, documents, or data transmissions, or establish or exchange a
session key for these same purposes. Key management sometimes refers to the
process of storing protecting and escrowing the private component of the key
pair associated with the encryption certificate.
identity certificate – A
certificate that provides authentication of the identity claimed. Within the
NSS PKI, identity certificates may be used only for authentication or may be
used for both authentication and digital signatures.
[CNSSI_4009:2010]
(I) A certificate document
in the form of a digital data object (a data object used by a computer) to
which is appended a computed digital signature value that depends on the data
object. (See: attribute certificate, public-key certificate.) [RFC4949:2007]
an entity's data rendered
unforgettable with the private or secret key of a certification authority. [ISO-19790:2006]
