The purpose of a checksum on an amount field in an electronic data interchange (EDI)
communication of financial transactions is to ensure:

A.
integrity.

B.
authenticity.

C.
authorization.

D.
nonrepudiation.

Explanation:
A checksum calculated on an amount field and included in the EDI communication can be used to
identify unauthorized modifications. Authenticity and authorization cannot be established by a
checksum alone and need other controls. Nonrepudiation can beensured by using digital signatures.
