Which of the following security features do email signatures provide?

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 toverify

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.
