Question

Quizplus · Accepted Answer

Asymmetric-key cryptography is often used for short messages because it allows secure communication without the need for a shared secret key. This is particularly useful for situations where a quick exchange of sensitive information is required, such as in online banking or email communication. With asymmetric-key cryptography, each user has a public and private key pair, which can be used to encrypt and decrypt messages. Because the public key can be shared with anyone, it is easy to initiate a secure communication without a need for prior communication or a shared secret key.
