Resolving Key Exchange Issues with Two-Key Systems Asymmetric cryptography replaces the shared secret of symmetric systems with a pair of keys, where one is public and the other remains private. Public keys are distributed openly in the network while the private keys are securely kept by their owners. This dual-key mechanism overcomes the challenge of securely exchanging keys and streamlines secure communication.
Secure Messaging via Recipient’s Public Key Messages are secured by encrypting them with the recipient’s public key, ensuring only the corresponding private key can decrypt them. Other encryption approaches using the sender’s keys either block proper decryption or expose the message to unauthorized parties. This practice is exemplified by the RSA algorithm and the requirement of two keys per node, emphasizing its practical importance.
