Vickie recently gathered digital evidence and would like to be able to provide future users of that evidence with the ability to verify non-repudiation. How can she provide this?
A. Generate a hash value from the evidence
B. Digitally sign the evidence
C. Encrypt the evidence
D. Generate a checksum from the evidence
Correct Answer: B
Using a hash value or checksum can verify that the evidence was not altered, but does not provide non-repudiation. Encrypting the evidence protects it from unauthorized disclosure and also verifies integrity, but it does not provide non-repudiation. Vickie can provide non-repudiation by digitally signing the evidence with her private key.
