Embodiment 1
[0027] figure 1 A schematic structural diagram of the electronic signature device of the present invention is shown, see figure 1 , the electronic signature device 10 includes: an adapter 101 and an OTP token 102 .
[0028] The electronic signature device 10 is connected to the terminal 20, wherein the electronic signature device 10 is connected to the terminal 20 through an adapter 101. Specifically, the adapter 101 can be connected to the terminal 20 through an interface, and the interface can be an audio interface or a USB interface or can carry data The special-shaped interface for transmission (such as Apple's DOCK interface, etc.); the terminal can be a mobile phone, a tablet computer, a notebook or a personal computer, etc.
[0029] The adapter 101 receives the data to be signed from the terminal 20, and sends the data to be signed to the OTP token 102 by wireless; the OTO token 102 receives the data to be signed by wireless, and outputs and displays the data to be sig...
Embodiment 2
[0034] figure 2 A schematic structural diagram of another embodiment of the electronic signature device of the present invention is shown, see figure 2 , the electronic signature device 10 includes an adapter 101 and an OTP token 102 .
[0035] in:
[0036] Adapter 101 includes: interface 1011, security chip 1012 and wireless communication module 1013, wherein: interface 1011 receives data to be signed from terminal 20, sends data to be signed to OTO token 102 through wireless communication module 1013; Wireless communication module 1013 will The received confirmation instruction is transmitted to the security chip 1012; the security chip 1012 signs the data to be signed according to the confirmation instruction, obtains the signature data, and transmits it to the terminal 20 through the interface 1011.
[0037]OTP token 102 includes: transceiver module 1021, analysis module 1022, button 1023 and display screen 1024; transceiver module 1021 receives and obtains the data to...
Embodiment 3
[0044] image 3 shows a schematic structural diagram of another embodiment of the electronic signature device of the present invention, see image 3 The difference between this embodiment and Embodiment 2 is that the communication between the adapter 101 and the OTP token 102 is carried out by means of optical transmission. in:
[0045] The wireless communication module 1013 of the adapter 101 is an optical transmission module, including: a first optical transceiver unit 1013a, the first optical transceiver unit 1013a converts the received data to be signed into a first optical signal, and sends the first optical signal to the dynamic Password token 102; the first optical transceiver unit 1013a receives the second optical signal containing the confirmation instruction sent by the dynamic password token, converts the second optical signal into a confirmation instruction, and outputs the confirmation instruction to the security chip 1012.
[0046] When the transceiver module 1...
