Abstract
This application pertains to encryption/decryption methods and related apparatuses. A communication device receives an initial layer-3 message. The initial layer-3 message includes an indication indicating that a part of the initial layer-3 message is encrypted. The communication device generates a keystream, and decrypts the encrypted part of the initial layer-3 message by performing an exclusive OR operation on the keystream and the initial layer-3 message.
