Which
of the following are the goals of a public key infrastructure (PKI)?
Each correct answer represents a part of the solution. Choose all that apply.
A.
Authenticity
B.
Globalization
C.
Mobility
D.
Integrity
E.
Confidentiality
F.
Nonrepudiation
Explanation:
The goals of a PKI (Public Key Infrastructure) are as follows:
Confidentiality: A PKI encrypts stored or transmitted data.
Integrity: A PKI digitally signs the data. A digital signature can identify whether the data is modified
by another user or not.
Authenticity: A PKI uses several authentication methods to authenticate the users. Authentication
data produces a message digest by
passing through hash algorithms. The message digest is digitally signed by using the sender’s private
key to verify that this message
digest is produced by the sender.
Nonrepudiation: The digital signature of the data offers a way to proof the integrity and origin of the
data. A third party can verify this
integrity and origin of the data at any time. The owner of the certificate cannot disprove this
verification.
Answer options C and B are incorrect. These are not the goals of a public key infrastructure.
