Solution
Vickie can provide future users with the ability to verify non-repudiation by digitally signing the evidence. Here's how she can do it:
-
First, she needs to have a digital signature. This is a mathematical scheme for verifying the authenticity of digital messages or documents. A valid digital signature gives a recipient reason to believe that the message was created by a known sender (authentication), that the sender cannot deny having sent the message (non-repudiation), and that the message was not altered in transit (integrity).
-
Once she has a digital signature, she can apply it to the digital evidence. This is usually done using a digital signature software or service.
-
The digital signature will then be attached to the digital evidence. This signature will contain information about the sender and the time the document was signed.
-
When future users receive the digital evidence, they can check the digital signature to verify non-repudiation. They can do this by using a digital signature verification software or service. If the digital signature is valid, then they can be sure that the digital evidence was indeed from Vickie and that it was not altered after she signed it.
So, the correct answer to your question is: Digitally sign the evidence.

To enhance non-repudiation and integrity, you plan to implement digital signatures for documents and software releases. The selected cryptographic technique must convincingly verify the authenticity of digital messages or documents, provide a way to verify the authenticity and integrity of messages, ensure that a message or document has not been altered, and the sender is authenticated, and most importantly, be widely accepted for legal and financial documents to establish trust.

The assurance that someone cannot deny the validity of something is Question 2Select one:a.Non-repudiationb.Authenticationc.Auditing
True or false. The legal concept of nonrepudiation provides assurance that an individual cannot deny having digitally signed a document or been party to a transaction. As the sum total of evidence that proves to the court's satisfaction that only one person could have executed that transaction, this concept exists because businesses want to prove it was one person's computer, ID, and digital signature, and that the person's transaction that cannot be repudiated.
