Question

What is the most obvious means of providing non-repudiation in a cryptography system?

a) Shared secret keys
b) Digital signatures
c) Hashing values
d) Public keys

Answer 1

Digital signatures are the most obvious means of providing non-repudiation in a cryptography system.

Step-by-step explanation:

The most obvious means of providing non-repudiation in a cryptography system is through digital signatures. Digital signatures are used to verify the authenticity and integrity of a message or document. They are created using the sender's private key, and can be verified using the sender's public key. This ensures that the sender cannot deny sending the message or altering its contents.
