5. Describe the concept behind a digital signature and explain how it relates to cybersecurity by providing a hypothetical example of a situation in which a digital signature could enhance cybersecurity

Could help when two doctors have to approve a patients treatment, or when two workers of the same company are working on classified information.

Explanation:

A digital signature creates a stamp on a document, that has time, location and is used to assure that the right person was the one that signed off the document and that no one changed the message or the content of the document between the signer and the receiver.

This helps in providing security and a legal frame to digital documents.
