Since the public key has become so important in the encryption and the decryption of the ciphertext messages between the sending and receiving parties and given the nature of its public role in the overall communication process, great pains and extensive research have been taken to create an infrastructure which would make the process of creating and sending keys much more secure and robust.
In fact, this infrastructure is a very sophisticated form of asymmetric cryptography, and it is known as the “Public Key Infrastructure” or “PKI” for short. The basic premise of PKI is to help create, organize, store, distribute and maintain the public keys.
