Which of the following manages the digital certificate life
cycle to ensure adequate security and controls exist in
digital signature applications related to e-commerce?
A. Registration authority
B. Certification authority
C. Certification relocation list
D. Certification practice statement
Answer / guest
Answer: B
The certification authority (CA) maintains a directory of
digital certificates for the reference of those receiving
them. It manages the certificate life cycle, including
certificate directory maintenance and certificate revocation
list maintenance and publication. Choice A is not correct
because a registration authority is an optional entity that
is responsibile for the administrative tasks associated with
registering the end entity that is the subject of the
certificate issued by the CA. Choice C is incorrect since a
CRL is an instrument for checking the continued validity of
the certificates for which the CA has responsibility. Choice
D is incorrect because a certification practice statement is
a detailed set of rules governing the certificate
authority's operations.
