Abstract
Provided are identifier (ID)-based encryption and decryption methods and apparatuses for the methods. The ID-based encryption method includes having, at a transmitting terminal, a transmitting-side private key corresponding to a transmitting-side ID issued by a key issuing server, generating, at the transmitting terminal, a session key using the transmitting-side ID, a receiving-side ID, and the transmitting-side private key, extracting, at the transmitting terminal, a secret key from at least a part of the session key, and encrypting, at the transmitting terminal, a message using a previously set encryption algorithm and the secret key.
