METHOD FOR VERIFYING ACCESS REQUEST, USER TERMINAL, AND BASE STATION

Abstract: described are a method for verifying an access request, a user terminal, and a base station. the method comprises: generating an access request message, wherein the access request message carries a ciphertext and a signature, the ciphertext is determined on the basis of a base station public key of a base station of a cell where a user terminal is located, and an identity identifier of the user terminal, and the signature is determined on the basis of a terminal private key and the identity identifier of the user terminal; and sending the access request message to the base station, wherein the access request message is used by the base station to determine, according to the signature and the ciphertext which are obtained by analyzing the access request message, whether the user terminal is legitimate so as to determine whether to allow the user terminal to access.
