Option D is correct because a digital signature is unique to the sender using it, as it depends on the sender's private key, which only the sender knows and controls. No one else can create a valid digital signature with the same private key, and no one can forge or modify a digital signature without being detected.
Option A is incorrect because a digital signature is not under control of the receiver, but rather under control of the sender. The receiver can only verify the digital signature, but cannot create or modify it.
Option B is incorrect because a digital signature is not capable of authorization, but rather capable of authentication. Authorization is the process of granting or denying access to resources based on predefined rules or policies. Authentication is the process of verifying the identity or legitimacy of a person or entity. A digital signature can authenticate the sender of a document, but it cannot authorize what actions the receiver can perform on the document.
Option C is incorrect because a digital signature does not dynamically validate modifications of data, but rather statically validates the integrity of data. A digital signature is based on a snapshot of the document at the time of signing, and any subsequent changes to the document will invalidate the digital signature. A digital signature does not monitor or update itself based on data modifications.
