Description of drawings
Fig. 1 is the external structure synoptic diagram of the digital postage black box of a kind of embodiment of invention.
Embodiment
Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.
As shown in Figure 1, digital postage black box of the present invention has three big functions: store the letter of identity of digital postage black box, and the 2nd, to the registering capital to, check and write off of postage (reducing) and storage, the 3rd, to output print postage information with generate the postage check code.
Described interface module 60 adopts usb modes, conveniently uses and takes care of, and no the time, it can be pulled up, and is stored in safe position.
Described identity information module 30 stores the identity information of digital postage black box.This identity information is provided by the official (post office that has the right to authorize) of outside, to determine the identity of this numeral postage black box.The identity information module 30 of this identity information one-time write numeral postage black box can not be revised.Each when using described digital postage black box, need read this identity information by interface module 60, and need its legitimacy of checking, comprise whether this identity information is provided by official, whether in the term of validity etc.
Identity information, identity information is originally cancelled it by official.The corresponding unique identity information of digital postage black box.
In order further to strengthen confidentiality, digital postage black box is scrapped or when damaging, also can be by official with its letter of identity calcellation as identity information, and the identity information of postage black box loses its validity, can not re-use.
The postage information stores is 21 li of the postage information memory cells of postage module 20, and postage information comprises: postage data and e-mail messages.The quantity of postage data representation postage, e-mail messages are represented the letters information relevant with postage, as kind of letters etc., and different letters, the postage data of required output are different.
By postage input block 22 input postage information, and, check and write off unit 23 by postage and check and write off the postage information of having exported according to the postage information of exporting.
Before first the use, postage is initialized as zero earlier, write to postage input block 22 by interface module 60 and register capital to algorithm, and check and write off unit 23 to money and write and check and write off algorithm.
Before use, must carry out postage earlier and register capital to, outside postage information is by interface module 10, and the processing of process postage input block 22 writes postage information memory cell 21.And this postage information is to be stored in the described postage information memory cell 21 in the mode of encrypting.
This numeral postage black box can be read information in the described postage information memory cell 21 by interface module 60.
Information in the described postage information memory cell 21 is checked and write off unit 23 and is checked and write off the algorithm except register capital to algorithm and the postage of postage input block 22, and other any programs all cannot be changed the postage of storing in the black box.
Numeral postage black box is when losing or scrapping, by can cancel postage information in its described postage information memory cell 21 of official.
Before the digital postage that each digital postage black box output is encrypted, when will export postage information, cryptographic algorithm unit 12 in the described encrypting module 10 goes out corresponding postage check code according to the postage information that will export according to private key and cryptographic algorithm computations.Outside system of official can judge the true and false of this postage check code by public key verification.
The each generation after the postage check code, under the control of the Task Distribution control module 41 of control module 40, described postage is checked and write off unit 23 and is checked and write off corresponding postage.
When outside system of official need be new postage information input digit postage black box, the PKI that needs to use the postage black box was encrypted.Numeral postage black box can obtain its postage information expressly by private key and enciphering and deciphering algorithm deciphering thereof.
Interface module 60: be used to import the special interface program, and carry out the exchange of information for external system and digital postage black box.
Driver element 42: the peripheral operation system respective drive program that digital postage black box uses ensures that digital postage black box can normally use on its operating system.
