The PRIMARY reason for using digital signatures is to ensure data:

A.
confidentiality.

B.
integrity.

C.
availability.

D.
timeliness.

Explanation:

Digital signatures provide integrity because the digital signature of a signed message (file, mail,
document, etc.) changes every time a single bit of the document changes; thus, a signed
document cannot be altered. Depending on the mechanism chosen to implement a digital
signature, the mechanism might be able to ensure data confidentiality or even timeliness, but this
is not assured. Availability is not related to digital signatures.
