Answer :A

The certificate authority manages the certificate life
cycle, including certificate directory maintenance and CRL
maintenance and publication. The CA attests, as a trusted
provider of the public/private key pairs, to the
authenticity of the owner to whom a public/private key pair
has been given. The digital certificate is composed of a
public key and identifying information about the owner of
the public key. It associates a public key with an
individual's identity. Certificates are e-documents,
digitally signed by a trusted entity and containing
information on individuals. The process entails the sender,
who is digitally signing a document with the digital
certificate attached issued by a trusted entity where the
receiver relies on the public key that is included in the
digital certificate, to authenticate the message. The
certification practice statement is the governance process
for CA operations. A CPS documents the high-level
practices, procedures and controls of a CA. The
registration authority attests, as a trusted provider of
the public/private key pairs, to the authenticity of the
owner to whom a public/private key pair has been provided.
In other words, the registration authority performs the
process of identification and authentication by
establishing a link between the identity of the requesting
person or organization and the public key. As a brief note,
a CA manages and issues certificates, whereas a RA is
responsible for identifying and authenticating subscribers,
but does not sign or issue certificates. Definitions can be

Answer: D

The registration authority manages the certificate life
cycle, including certificate directory maintenance and
certificate revocation list (CRL) maintenance and
publication. The certificate authority attests, as a trusted
provider of the public/private key pairs, to the
authenticity of the owner to whom a public/private key pair
has been given. The digital certificate is composed of a
public key together with identifying information about the
owner of the public key. It associates a public key with an
individual's identity. Certificates are e-documents
digitally signed by a trusted entity containing information
on individuals. The process entails the sender digitally
signing a document with the digital certificate attached
issued by a trusted entity where the receiver relies on the
public key that is included in the digital certificate to
authenticate the message. The certification practice
statement is the governance process for CA operations.
