Which of the following security features do email signatures provide?
Email signatures provide two key security features: non-repudiation and sender authentication. Non-repudiation ensures that the sender cannot deny having sent the email, as the digital signature is created using the sender’s private key and can be verified by the recipient using the sender’s public key. Sender authentication allows the recipient to verify the identity of the sender, thus confirming that the email is from a legitimate source and mitigating risks associated with email spoofing and phishing.
A,D is correct. If need to choose, I go with A. A. Non-repudiation: Email signatures ensure that the sender of the email cannot deny having sent the message. This is achieved through the use of digital signatures, which are created using the sender’s private key. If the recipient can verify the signature using the sender’s public key, it confirms that the email was indeed sent by the sender and has not been altered. D. Sender authentication: Digital email signatures authenticate the sender of the email. When an email is digitally signed, the recipient can verify that the email actually came from the purported sender by checking the digital signature against the sender’s public key. This helps in confirming the identity of the sender and ensuring that the email is from a legitimate source.
Is this multiple choice or single choice question?
Email signatures are primarily used to authenticate the sender of an email message, ensuring that the recipient can trust the origin of the message and detect any tampering during transmission. This helps mitigate risks associated with email spoofing and phishing attacks by providing assurance of sender identity.
