Description
Technical Field
The invention relates to the field of network communication, in particular to an automatic switching method of a mobile network.
Background
The prior art also includes problems due to open channel delivery of session keys. The session key derived internally within the UICC (using Ks or Ks _ NAF in the derivation process) is delivered from the UICC to the terminal for subsequent use by the terminal in session encryption or decryption, and the process is performed over an unsecured channel. Thus, the eavesdropping agent can intercept the session key and encrypt or decrypt messages exchanged between the terminal and the network. In this event, many procedures that subsequently require the establishment of an HTTPS tunnel between the terminal and the NAF key center for the latter to derive and deliver (from the NAF key center) the local key (Ks _ local), such as user certificate establishment, will risk being breached. Since the local key itself is transmitted over the HTTPS tunnel, corruption of the session key will cause the local key to be corrupted. All these communications are then risky when the local key is used in the transmission of encrypted information between the UICC and the terminal, if the local key remains unchanged after reset or phone start-up.
In the prior art, after a user mobile terminal is accessed to an operator network, when key data transmission is performed with other terminals, risks of being stolen usually exist, such as stealing of keys, transaction passwords and the like.
