Abstract
The utility model is a PDA with an IC card which relates to a PDA and a personal figure auxiliary attesting the identity and accepting the information through the IC card. The utility model comprises an antenna, a high frequence reciver, a demodulator, a high frenquence magnifier, amodulator, a CPU, a touch screen, a memorizer, a keyboard, a general interface of I/O, an IC card and a power supply and is characterized in thatthe PDA is provided with an IC card socket and the IC card is arraged in the IC card socket which is comunicated with the CPU through the signal line.
Description
The palm PC (PDA) of the utility model band IC-card relates to is a kind ofly to carry out authentication and butt joint palm PC, the personal digital assistant that breath is decrypted of collecting mail with IC-card.
Existing palm PC (PDA) though, personal digital assistant can receive external information by wireless and wired mode, but above-mentioned information is public information, in transport process, easily obtained, so information privacy is very poor, can not authenticates recipient's identity effectively by the third party.
The purpose of this utility model is to provide a kind of palm PC with IC-card (PDA) at above-mentioned weak point, can encrypt all information that palm PC received, palm PC (PDA) with the band IC-card is decrypted, make palm PC can receive all kinds of enciphered messages, and carry out activities such as content choice, authentication and charging.
The palm PC (PDA) of band IC-card takes following scheme to realize: palm PC (PDA) structure of band IC-card comprises antenna, high-frequency receiver, detuner, radio-frequency amplifier, modulator, central processor CPU, touch-screen, storer ROM/RAM, keyboard, general-purpose interface I/O, IC-card, power supply.Palm PC (PDA) device has the IC-card socket, and the IC-card dress is inserted in the IC-card socket, and the IC-card socket links to each other with central processor CPU by signal wire.Antenna links to each other with high-frequency receiver, and high-frequency receiver links to each other with detuner by signal wire, and detuner links to each other with central processor CPU by signal wire.Central processing unit links to each other with modulator by signal wire, modulator links to each other with radio-frequency amplifier by signal wire, radio-frequency amplifier joins by signal wire and antenna and carries out signal output, and touch-screen links to each other with central processor CPU by signal wire, realizes showing, importing.Central processor CPU links to each other with storer ROM/RAM by signal wire, is used to deposit application program and data.Keyboard links to each other with central processor CPU by signal wire.General-purpose interface I/O links to each other with central processing unit by signal wire, the interface that provides palm PC (PDA) to be connected with other equipment.
The band IC-card palm PC (PDA) on common palm PC (PDA) basis device the IC-card socket, dress is inserted with IC-card, utilize the central processor CPU of PDA self that IC-card is carried out read-write operation, after palm PC (PDA) sent IC-card to carry out operations such as authentication, deciphering, charging by encrypting traffic wireless or that wireline interface is received by central processor CPU, the information after will deciphering again sent back to relevant treatment such as central processing unit shows, broadcast.Because the fabulous confidentiality of IC-card itself makes these operations be difficult to be decrypted.Because operation is all carried out in IC-card inside, the assailant also can't set about decoding from PDA software, so confidentiality is fine.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is palm PC (PDA) the structure block diagram of band IC-card.
With reference to accompanying drawing, palm PC (PDA) structure of band IC-card has antenna, high-frequency receiver, detuner, radio-frequency amplifier, modulator, central processor CPU, touch-screen, storer ROM/RAM, keyboard, general-purpose interface I/O, IC-card, power supply.Palm PC (PDA) device of band IC-card has the IC-card socket, the IC-card dress is inserted in the IC-card socket, the IC-card socket links to each other with central processor CPU by signal wire, antenna links to each other with high-frequency receiver, high-frequency receiver links to each other with detuner by signal wire, and detuner links to each other with central processor CPU by signal wire.Central processor CPU links to each other with modulator by signal wire, modulator links to each other with radio-frequency amplifier by signal wire, radio-frequency amplifier joins by signal wire and antenna, touch-screen links to each other with central processor CPU by signal wire, central processor CPU links to each other with storer ROM/RAM by signal wire, and keyboard links to each other with central processor CPU by signal wire.General-purpose interface I/O links to each other with central processing unit by signal wire, and power supply links to each other with the complete machine relative section.Central processor CPU can adopt NEC MIPS VR 41XX etc., and IC-card can adopt SLE66C80S etc.
With reference to accompanying drawing, central processor CPU in the palm PC (PDA) of band IC-card is a core, its application program and deposit data are in storer ROM and RAM, and keyboard and touch-screen provide input and output, the interface that general-purpose interface I/O provides palm PC PDA to be connected with other equipment.Modulator, detuner and high-frequency receiver, radio-frequency amplifier module and antenna provide PDA antenna mode and outside function of carrying out data communication.IC-card be intended for to data encrypt, computing such as deciphering, authentication, charging.Power unit provides the complete machine operating voltage.
