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 information assurance (IA) community, certificate usually implies public key certificate and can have the following types: A digital representation of information which at least (1) identifies the certification authority (CA) issuing it, (2) names or identifies its subscriber, (3) contains the subscriber’s public key, (4) identifies its operational period, and (5) is digitally signed by the certification authority issuing it. See cross certificate, encryption certificate, and identity certificate.

  A set of data that uniquely identifies a key pair owner that is authorized to use the key pair, contains the owner’s public key and possibly other information, and is digitally signed by a Certification Authority (i.e., a trusted party), thereby binding the public key to the owner.

  A data structure that contains an entity’s identifier(s), the entity's public key (including an indication of the associated set of domain parameters) and possibly other information, along with a signature on that data set that is generated by a trusted party, i.e., a certificate authority, thereby binding the public key to the included identifier(s).

  A set of data that uniquely identifies an entity, contains the entity’s public key and possibly other information, and is digitally signed by a trusted party, thereby binding the public key to the entity identified in the certificate.

  Also known as a digital certificate. A digital representation of information which at least 1. identifies the certification authority issuing it, 2. names or identifies its subscriber, 3. contains the subscriber's public key, 4. identifies its operational period, and 5. is digitally signed by the certification authority issuing it.
