In order to use asymmetric cryptography, each person receives a key pair; one public key and one private key. Each person's public key is published, while the private key is kept secret. The need for sender and receiver sharing information about the secret is eliminated. The only requirement is that public keys are associated with their users in a trusted (authenticated) manner.

A cryptography technique whereby each user has both a public key and a private key. Asymmetric systems have two primary uses, encryption and digital signatures.

Asymmetric Cryptography is a type of cryptography characterized by the fact that two different (but mathematically related) keys are used to perform the cryptographic operations.

Public-key cryptography; A modern branch of cryptography in which the algorithms employ a pair of keys (a public key and a private key) and use a different component of the pair for different steps of the algorithm.

A synonym for public key cryptography

(Also known as public key cryptography.) Encryption software that requires two keys public key and a private key. Encryption software users distribute their public key, but keep their private key to themselves. When someone wants to send an encrypted message, the sender uses the recipient's public key to encrypt the message, which can only be decrypted by the person who holds the corresponding private key. For example, Jack makes public key A and private key A, and Jill makes public key B and private key B. Jack and Jill exchange their public keys. Once they have exchanged keys, Jack can send an encrypted message to Jill by using Jill's public key B to scramble the message. Jill uses her private key B to unscramble it. If Jill wants to send an encrypted message to Jack, she uses Jack's public key A to scramble her message, which Jack can then unscramble with his private key A. Asymmetric cryptography is typically slower to execute electronically than symmetric cryptography.

Cryptography involving public keys, as opposed to cryptography making use of shared secrets. See Also: Symmetric cryptography

A form of cryptography in which a pair of keys is used for encryption and decryption, one key is advertised publicly and the other kept private. Objects encrypted with one key can only be decrypted with the other, thus a persons public key can be used to encrypt all messages sent to them by any party, but only the owner of that key can decrypt them using the associated private key.

In this Cryptography a Key Pair - Private and Public Key is used. Private Key is kept secret and the Public Key is Widely distributed.
