  A set of data that uniquely identifies a public key (which has a corresponding private key) and an owner that is authorized to use the key pair. The certificate 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 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 (e.g., using an X.509 certificate). Additional information in the certificate could specify how the key is used and its validity period.

  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).
