COMPUTER FUNDAMENTALS

Detailed explanation-1: -The benefits of asymmetric cryptography include: The key distribution problem is eliminated because there’s no need for exchanging keys. Security is increased since the private keys don’t ever have to be transmitted or revealed to anyone.

Detailed explanation-2: -Asymmetric encryption is used in key exchange, email security, Web security, and other encryption systems that require key exchange over the public network. Two keys (public and private), private key cannot be derived for the public, so the public key can be freely distributed without confidentially being compromised.

Detailed explanation-3: -Digital Signing: Asymmetric encryption is much better for digital signing, compared to symmetric encryption. The use of both a public and private key means the identity of the signer of the data can easily be known.

Detailed explanation-4: -Asymmetric Encryption uses two distinct, yet related keys. One key, the Public Key, is used for encryption and the other, the Private Key, is for decryption. As implied in the name, the Private Key is intended to be private so that only the authenticated recipient can decrypt the message.

Detailed explanation-5: -Symmetric cryptography is faster to run (in terms of both encryption and decryption) because the keys used are much shorter than they are in asymmetric cryptography. Additionally, the fact that only one key gets used (versus two for asymmetric cryptography) also makes the entire process faster.
