Abstract:
Embodiments of the present invention disclose a key exchange method and apparatus, which relate to the communications field, and can enable user equipments establishing a D2D link to share a set of keys, and further, information security can be achieved when a user equipment transmits service data or a signaling message through a Ud interface. A network device acquires a first key, and sends a message including the first key to a second user equipment, so that the second user equipment uses, when communicating with a first user equipment by using a D2D link, the first key to protect transmitted information. Embodiments of the present invention are applicable to an exchange process of keys for protecting data on a D2D link.

Claim (Index 15):
The apparatus according to  claim 14 , wherein\n the apparatus further comprises a receiver, configured to receive an encryption algorithm identifier; and the processor is further configured to, after the processor acquires the first key:\n generate an encryption key according to the first key and the encryption algorithm identifier; and \n protect the transmitted information implemented by encrypting, by using the encryption key and an encryption algorithm corresponding to the encryption algorithm identifier, the information transmitted on the D2D link.
