Symmetric encryption requires one key known by both parties. Asymmetric encryption uses two keys, one encryption key known publicly and one decryption key known only by the recipient.

Public key encryption is also known as asymmetric encryption?
Yes. Public Key encryption (or asymmetric encryption) requires a pair of keys; a public and a private key for exchanging data in a secure manner.
Are the asymmetric encryption keys mathematically related to one another?
Yes
Are asymmetric encryption keys mathematically related to one another?
Yes
In asymmetric encryption the keys mathematically related to one another?
Yes
Does a VPN use symmetric or asymmetric encryption?
PKI must use asymmetric encryption because it is managing the keys in many cases. This implies the use of public and private key pairs, which is asymmetric.
Are In asymmetric encryption the keys are mathematically related to one another?
Yes
What kind of encryption uses the concept of public keys?
Asymmetric encryption employs the use of public/private key pairs.
True or false In asymmetric encryption the keys are mathematically related to one another?
true
Asymmetric encryption involves?
The asymmetric key algorithms are used to create a mathematically related key pair: a secret private keyand a published public key.
What is the meaning of asymmetric encryption?
Asymmetric Encryption is a form of Encryption where keys come in pairs. What one key encrypts, only the other can decrypt. Frequently (but not necessarily), the keys are interchangeable, in the sense that if key A encrypts a message, then B can decrypt it, and if key B encrypts a message, then key A can decrypt it. While common, this property is not essential to asymmetric encryption. Asymmetric Encryption is also known as Public Key Cryptography, since users typically create a matching key pair, and make one public while keeping the other secret. Users can "sign" messages by encrypting them with their private keys. This is effective since any message recipient can verify that the user's public key can decrypt the message, and thus prove that the user's secret key was used to encrypt it. If the user's secret key is, in fact, secret, then it follows that the user, and not some impostor, really sent the message. Users can send secret messages by encrypting a message with the recipient's public key. In this case, only the intended recipient can decrypt the message, since only that user should have access to the required secret key. The key to successful use of Asymmetric Encryption is a Key Management system, which implements a Public Key Infrastructure. Without this, it is difficult to establish the reliability of public keys, or even to conveniently find suitable ones.
Is pgp encryption safer than other encryptions?
"Evaluating cryptography is difficult since without 'breaking' the encryption its hard to say whether one encryption is better or not. Pretty Good Encryption (PGP) is asymmetric, that is the encryption and decryption keys are different which may give it an edge on symmetric encryption."
Which type of encryption technology uses two keys to encrypt and decrypt data?
If the keys are different, then it is asymmetrical. If it is the same key used twice to encode and decode; then it is symmetrical.
