Asymmetric Encryption Asymmetric encryption was invented independently by academic cryptographers at Stanford University in the USA and by military cryptographers at Britain's GCHQ. It is the basis of public key infrastructure (see PKI), although a 'public' key is not strictly necessary. Information is encrypted by using one key of a pair and can only be de-crypted using the other key. In public key encryption, this allows anyone to communicate securely with an entity using his/her/its public key as the entity can de-crypt the information using their (secret) private key.
