When smart card is extraneous communication, carry out two-way authentication, guarantee the legitimacy of card and equipment. When smart card is connected with far-end server by network, at first will be by the authentication of far-end server, smart card also will be verified the legitimacy of far-end server simultaneously. Then just can carry out legal communication process. The data adds ciphertext data by the interim key that a front data flow and main key produce in the communication process, and uses digital signature, to prevent the illegal modifications data and to be confirmed to be the data (digital signature has uniqueness) that this user is sent.

The embedded type CPU StrongARM SA1110 of processor adopting Intel Company consists of, and SA1110 is the powerful microprocessor that INTEL Corp. specially releases for Embedded Application. The SA1110 processor is the microprocessor of a high-performance, low-power consumption, and processor speed can be configured to 133-206MHZ. The system storage device is configured to 32M synchronous memories DRAM, 32M flash memory FLASH. Digital telephone is replied the TP3054 codec chip that equipment (TAD) is based on DSP Group 6417c TAD chip and National Semiconductor, receiver directly links to each other with the TAD codec chip, and the TP3054 codec links to each other with PSTN by telephone line interface circuit. Adopt the CH1837C DAA of Cermetek company. The external voice suggestion ROM of DSP Group 6127C and message storage FLASH. V.90 the modem of standard and touch-screen, Philip advanced modulation demodulation speech simulation front end UCB1300 be front end interface circuit. It is directly linked on the telephone line by DAA. Touch-screen is inputted as data, links UCB1300. The Ethernet controller adopts the ISA/PCMCIA monolithic full duplex Ethernet controller LAN91C96 of Standard Microsystems. Serial EEPROM storage networking configuration information. Keyboard is by SPI (SPI) control FKB1406 keyboard. The Keyboard Control device uses the UR5HCSPI-106-FB of USAR company. The TFDS6000D of infrared interface TEMIC semiconductor company for two rapidly become popular outer digital analog transceiver (115kb/s and 4Mb/s), link to each other with SA1110 serial ports 2. Transceiver receives from the data signal of SA1110 and is converted to infrared pulse signal, or receives infrared pulse signal and be converted to data signal.

IC-card (claiming again smart card) has the advantages such as memory space is large, good, the anti-interference ability of data confidentiality is strong, storage is reliable, card-reading apparatus is simple, service speed is fast, the off line ability to work is strong, the optimum carrier that makes it to become the sign identity and deposit security information has more extensive, deep application prospect than credit card; And the various authentications from shopping at network to following information-intensive society, needed just such information carrier---IC-card is as instrument of the carrier of the payment front end of online transaction, user's certificate and signature, encryption etc., play a part very importantly, the application tool of safe and convenient is provided for shopping at network. Referring to Fig. 3, IC-card read write line UB2, UB1 connect CPU, and CPU IC card reader adopts the TDA8007 conduct of PHILIPS Co. and the interface chip of SA1110. TDA8007 has two read-write interfaces, a position SAM card interface, another IC-card interface.

The intelligent card interface circuit adopts the TDA8007 of PHILIPS Co.. TDA8007 is by two interfaces, a secure access module (SAM card) interface, and another is intelligent card interface. TDA8007 is operated under the non-multiplex mode (being address and data separating), and the read signal (OE#) of embedded processing device SA1110, write signal (WE#), sheet select signal (CS4#), read-write direction control signal (RD/WR#) to form the read-write sequence of TDA8007 by combinational logic. A0-A3 is address signal, and D0-D7 is 8 bit data signals.

Referring to Fig. 2, the utility model modem adopt Philip advanced modulation demodulation speech simulation front end UCB1300 be front end interface circuit, link to each other with SA1110 by serial bus interface, the serial line interface signal comprises SFRM_C, SCLK_C, TXD_C, RXD_C, and GPI023_UCB_IRQ is the middle break signal that UCB1300 sends to SA1110. UCB1300 is integrated in 56kmodem and audio frequency mould/number conversion in the chip piece. Modem is directly connected on the telephone wire by DAA. The sound coder of UCB1300, it is the simulation front end of IP voice bag, is about to the analog signal conversion data signal of sound pick-up, again by SA1110 with the voice data compression, packing is processed, and the IP bag is sent by modem or ether network; SA1110 unties the IP packet of modem or the reception of ether network and decompresses simultaneously, exports the voice signal through the sound encoding and decoding of UCB1300 again.

Shown in Fig. 4,5, the digital speech of telephone answering employing DSP GROUP company/signal processing chip D6571. D6571 controls its read-write by SA1110, and CS2# is that the sheet of D6571 selects signal, writes order word and the state of reading D6571 by 8 position datawires to D6571. ROM 7512 and FLASH K9F4008 deposit respectively information of voice prompt and message information. D6571 is by control line TAD_FLASH_CLE, TAD_FLASH_ALE, TAD_FLASH_WR#, TAD_FLASH_RD#, TAD_FLASH_CEO# control FLASH K9F4008, by TAD_FLASH_CE2#, TAD_FLASH_RD# control ROM 7512. D6571 receives on the telephone wire by TP3054 and CPC5604, and simultaneously D6571 receives MIC and spkeaker by TP3054, through MIC with voice recording in FLASH, through SPEAKER with the message playback among the flash.

Other discrete devices of LCB110 and LDA110 form the indication of dislodging machine and quiet indication notice SA1110 deals with.

The handset plug receiver of answering the call among the figure, telephone line plug answers the call on the line.

As shown in Figure 1, the utility model embedded OS (Embedded Operating System, EOS) is selected the Windows CE product of Microsoft company. The kernel of Windows CE is smaller, is the OS of 32 multithreadings, has the open architecture that can be used by various device, and has retractility, can support the trend of following embedded, the mobile or media product. The advantage of Windows CE is to have very strong portability, can independently select CPU, and non-power management capabilities by force is provided. In addition, Windows CE also has built-in standard traffic ability, can realize accessing Internet and receives and dispatches E-mail or browse the function of WWW. What is particularly worth mentioning is that it has the similar user interface with Windows, the user uses not only convenient but also simple.
