Answer:
TRUE
Step-by-step explanation:
TRUE. Public key encryption, also known as asymmetric key encryption, uses two keys – a public key and a private key – to encrypt and decrypt messages. The public key is widely distributed and used by anyone who wants to communicate securely with the owner of the private key. The private key is kept secret and only known to the owner, who uses it to decrypt messages sent to them. This two-key system allows for secure communication without the need for a pre-shared secret key. Public key encryption is commonly used in online transactions, secure email communication, and digital signatures.
