Abstract

The invention provides a security smart card system and a password service method thereof. The system comprises an interface module, a controller and a plurality of functional modules; the interface module is electrically connected to the controller and is used for providing a sector read-write interface for the upper computer so as to realize data interaction between the upper computer and the controller; the controller is used for providing sectors with different functions so as to receive data packets with different service requirements, each sector corresponds to a specified function module, and the controller adopts the sectors with different functions to distribute the data packets with different service requirements to the specified function module, wherein the sectors with different functions are jointly appointed by the controller and the upper computer; and the plurality of functional modules comprise a security chip and a soft password module, the security chip is electrically connected to the controller and is used for providing hardware encryption and decryption services, and the soft password module is arranged in the controller and is used for providing software password services. According to the safety intelligent card system, high-speed password service is provided for the upper computer.

Description

technical field [0001] The invention relates to the technical field of smart cards and safety, in particular to a safety smart card system and a password service method thereof. Background technique [0002] Smart cards include SD cards, TF cards and so on. Taking an SD card as an example, the SD card is mainly used for storing data and is widely used in portable devices. A traditional SD card mainly includes an interface module, a controller and a storage module, the interface module is connected to the controller, the controller is connected to the storage module, and the upper computer sends the data to the controller through the interface module. Read and write instructions, the controller writes corresponding data to the storage module according to the write instruction, and reads corresponding data from the storage module according to the read instruction. [0003] The traditional SD card can only simply receive and store the data written by the host computer. Most o...
