Method and system for safeguarding user access
ActiveCN101835156AImprove protectionNot vulnerableSecurity arrangementSelf-modifying codeNetwork-attached storage
The invention provides a method and a system for safeguarding user access. The method is applied to an LTE (Long Term Evolution) system. UE accessing the LTE system issues an access safety activating command, verifies the integrity of a safe mode command message in an activating process and sends a verification failure message to a network side if verification fails, wherein preset discrimination information is added to the verification failure message, and the network side receives the verification failure message, detects whether the discrimination information is legal or not and restores the configuration before activation if the discrimination information is legal. In traditional NAS (Network Attached Storage) SMC (Self-Modifying Code) and AS SMC flows, the safeguarding of the verification failure message is enhanced so that the network side is hardly attacked by false messages.
