Election equipment receives a vendor software update. Which cryptographic result does verifying the publisher's digital signature on the package primarily provide?
Select an answer to reveal the explanation.
Short Explanation
A digital signature is the vendor's tamper-evident wax seal: if the seal verifies, you know who published the package and that nobody swapped bits on the way. It is not encryption for secrecy and it does not keep the download site online.
Full Explanation
Digital signatures use asymmetric cryptography so verifiers can confirm a package was signed by the holder of the private key and that the content was not altered after signing. Those properties provide authenticity and integrity and support non-repudiation. Signatures do not encrypt the package for confidentiality, guarantee portal availability, or serve as a compression mechanism.
