Question
Which feature of digital certificates prevents tampering and ensures data integrity?Expiration datesDigital signaturesEncryption algorithmsCertificate chains
Solution
The feature of digital certificates that prevents tampering and ensures data integrity is Digital signatures.
Here's a step-by-step explanation:
-
A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents.
-
When a digital certificate is signed, the signature confirms that the certificate data has not been tampered with since it was signed.
-
The digital signature is created using a hash function and the private key of the signer.
-
When the certificate is used, the receiver can use the public key of the signer to verify the signature and confirm the integrity of the certificate data.
-
Therefore, the digital signature feature of digital certificates prevents tampering and ensures data integrity.
