The present invention discloses a safety authentication method. The method is applied to a safety authentication system, wherein the safety authentication system includes a terminal device and an SIM card, wherein the SIM card is provided with a built-in TEE. The method includes the following steps that: a safety authentication request initiated by the terminal device is received; when the safety authentication request is valid, to-be-authenticated data sent by the terminal device are received through a trusted application, wherein the trusted application operates in the built-in TEE in the SIM card; a trusted driver in the terminal device is called and is utilized to control the external device of the terminal device, the trusted driver and the TEE have a unique calling relationship; and the external device of the terminal device is utilized to perform authentication operation on the to-be-authenticated data so as to obtain an authentication result, and the authentication result is sent to the terminal device. The present invention adopted, it only needs to use the SIM card with a lower replacement frequency to enable the terminal device to achieve safety authentication under the TEE, and therefore, the practicability and safety of the method can be improved.
Description
technical field [0001] Embodiments of the present invention relate to the field of information security, and in particular, to a security authentication method, related device, and system. Background technique [0002] With the development of mobile communication technology, terminal equipment has become an indispensable equipment for people. Terminal equipment is no longer a simple voice communication tool, but has the processing power of a computer and network functions, and has been widely used in social networking, transportation, finance, shopping, etc. [0003] At present, in order to eliminate the security risks existing in the current terminal equipment, some solutions have been proposed, such as adding security applications inside the terminal equipment, such applications can scan whether the environment where the user enters information is safe, so as to provide users with more secure experience. [0004] However, only a small number of terminal devices are insta...
