Description of the invention: [Technical field to which the invention pertains] The present invention relates to a mechanism for viewing a seed device, and a communication mechanism for a security device, particularly in a memory interface. [Prior Art] At present, the safety of riding (4) security is the most appropriate, and it is the application of smart cards. Compared with the general plastic cards widely used in the market, smart cards have many good characteristics, such as large memory capacity, logical computing and data control capabilities, high security and low cost, among which high security. For smart cards, it is better than other plastic magnetic strips. Wisdom has a multi-layered security protection including identification card authenticity, cardholder identification, data access control and data encryption, making high security an important feature. Knowing that in the smart card forum, the remittance of the remittance, for the wisdom to discuss - a formal definition of the Hui Hui card is a frequency circuit card with a power of ability. Inside the smart card is a microcomputer mi and operating system, which makes it have the ability to perform operations and save the hidden Wei. The appearance of the smart card and the size of the lang-like card - just a small piece of ic chip 'make the original ordinary - small card with logical operation,: work & the power of all the reading and writing of the smart card The entry must be through a dedicated Smart Card Reader. 200924479 In the smart card, you can pre-store the encryption software such as RSA, Hash, etc. or the circuit board with Yang Mi Ship. Frequent bribery in the card's soft and hard body set (four) scale reading card Shun Qianquan (four) Er Mu mutual authentication function, you can achieve the purpose of authenticating the card. In the current scheme of integrating smart cards and flash memory cards, for example, the Republic of China Patent Notice No. __ "Portable Storage Device for Identifying User Identity", Republic of China Patent Notice No. No. _64 "Multi-Function Identification Card" Dachang, Weichao Smart Card provided verification Wei, into the secret protection flash memory card information. In addition, although the smart card has the above advantages, compared with the flash memory card, there are still a few smart reading interfaces in the electronic electronic device, so that the wisdom of the wisdom pin has been affected. . In order to solve this problem, in the "Patent Patent No. M28_" "1 Wisdom Media Memory Card", the structure of the flash memory card and the smart (8) is turned over through the memory card interface. However, in this conventional projection, in order to check the received write command to the flash memory module 16 or the security device module 14, it is usually necessary to check the format of the write command itself. So that it will be too complicated in practice. The main purpose of the present invention is to provide a security device communication mechanism based on a memory interface, which uses the packet header of the judgment data packet to additionally include special predetermined data, so as to determine that the data packet is forwarded to the security device module. Group or flash memory module' for integration purposes. Based on the above object, the communication mechanism of the security device based on the memory interface of the present invention mainly comprises a miscellaneous interface, a security recording module, a flash memory, and a control panel that is electrically connected to the domain age® and the county age. Due to the data packet from the memory interface, a special predetermined cake is additionally included in the packet header, which enables the control panel to include the predetermined data in the (4) packet header to transmit the data packet to the health device. If the packet from the memory interface does not contain (4) the predetermined data, the control module will: the secret packet to the flash memory group. Further, we will learn more about the invention and the model of the Japanese-style ginseng.

"The first 丨 示" is based on the memory interface in the present day and month: _ towel, mainly including a clock interface 丨., security device module Shaanxi flash δ 忆 recall plate group 16, and electrical connection to the memory interface 1 保密, security device 200924479 set module 14, and flash memory The control module 12 of the module 16. Among them, the memory interface ίο can be electrically connected to the host interface, such as SDI 〇 (SD card 1 / 〇 interface), and accept data packets from the host side. The group 14 is a smart card module or a chip card module or a java card, a user identification card, a bio-protective card and a biometric identity card. The interface between the control module 12 and the security device module μ can be a serial (Serial peripherai interfaee, spi), Universal Serial Bus (USB) or ISO 7816.
