EXTERNAL MEMORY, METHOD FOR PROVIDING PASSWORD SERVICE, AND SERVICE PROCESSING DEVICE

Multiple embodiments disclosed in the present description provide an external memory, a method for providing a password service, and a service processing device. Password service capability is built into an external memory of a service processing device, that is, a password service hardware module is built in the external memory, so that the external memory not only has storage capability, but also has password service capability. A CPU of the service processing device may invoke, by means of connection with the external memory, the password service hardware module in the external memory to provide a password service, and the CPU may obtain a service result by means of the connection with the external memory, or can directly store the service result into a storage space of the external memory. De multiples modes de réalisation divulgués dans la présente description concernent une mémoire externe, un procédé de fourniture d'un service de mots de passe et un dispositif de traitement de service.
