<p>A realizing method for PUSH service of GAA and a device. The method includes the steps: the network side determines a PUSH service cryptographic key; the subscriber side communicates with the network side, and determines the PUSH service cryptographic key in accordance with the network side, and communicates with the network side using the PUSH service cryptographic key. By means of the method, the cryptographic key type of the PUSH service can be selected conveniently and agilely according to the actual application situation, and the network side and the subscriber side can select the derivation cryptographic key of the cryptographic key type meeting the requirement to communicate with each other.</p> |
