At the heart of PKC lies an asymmetric encryption system, a sophisticated mechanism that employs two distinct keys: a public key for encryption and a private key for decryption. This dual-key approach adds an extra layer of security to the communication process.

The use of separate keys for encryption and decryption is a pivotal aspect of PKC's security model. It ensures that only the intended recipient, who possesses the corresponding private key, can decipher the encrypted message.
