The invention belongs to the technical field of
information security, relates to transmission of digital information, and particularly discloses a locking
authentication device and a locking
authentication method. According to the application, a deep interaction architecture of the
mobile authentication device and the
network security device is adopted, and
security enhancement is realized through a three-level permission
verification mechanism. The
system firstly verifies the identity information of the
mobile authentication equipment, secondly verifies the binding relation of the equipment, and finally realizes continuous
authentication through a dynamically updated permission code. And when any permission
verification fails and exceeds the limit, the
mobile authentication equipment is automatically locked. The design ensures that only legal equipment passing a complete authentication process can access sensitive resources, and unauthorized access and replay attacks are continuously prevented in the process of providing
network security services. Compared with the prior art, according to the scheme, through authority level-to-level management and a dynamic updating mechanism, safety management and control of the whole process are achieved on the aspects of equipment authentication,
resource protection and service providing.
