Public-key cryptography

Abbreviation(s) and Synonym(s):

None

Definition(s):

  A form of cryptography that uses two related keys, a public key and a private key; the two keys have the property that, given the public key, it is computationally infeasible to derive the private key. For key establishment, public-key cryptography allows different parties to communicate securely without having prior access to a secret key that is shared, by using one or more pairs (public key and private key) of cryptographic keys.
