ITPEC IP October 2022 Question 41
ITPEC IP October 2022 — Question 41 of 100
A digital signature on the order data provides evidence of origin and integrity, supporting non-repudiation. The signer uses a private key, and the recipient verifies the signature with the corresponding public key. Altered order details invalidate verification.
Answer (c)
Why not others:
- an OS password controls local login but does not prove the signed order
- antivirus measures address malware
- encryption protects confidentiality but alone does not prove who submitted the order
Key rule: Digital signatures provide integrity, authentication, and evidence against denial; encryption primarily provides confidentiality.
