Explanation:

Email signatures provide non-repudiation, which ensures that the sender of an email cannot deny having sent it. A digital signature, when attached to an email, uses cryptographic techniques to verify the sender's identity and confirm the authenticity of the message. This feature helps establish trust by preventing tampering and ensuring the integrity of the communication. CASP+ emphasizes the role of digital signatures in ensuring non-repudiation in secure communication protocols.
