Abstract
A message protection method, user equipment, and a core network device are disclosed. The method includes: sending a request message on which no security protection is performed to the core network device, where the request message includes a first random number; receiving an abnormal response message, where the abnormal response message includes a third random number and a signature; and determining, based on the third random number, the signature, and an obtained credential, whether the abnormal response message is a valid message. According to the message protection method provided in the embodiments of the disclosure, security protection can be performed on a message transmitted before a security context is established between the user equipment and the core network device, so as to improve network communication security.
