Problems solved by technology

The invention patent with the patent number of CN101729641 discloses a machine-card separation voice code encryption telephone system. The invention aims at providing a communication security device with identity authentication with machine-card separation on the PSTN network, and technically achieves every Each call is encrypted every time, and the key disappears after use. Even if you get the postal encryption phone, you can't decrypt the previous communication data.
[0004] But so far, there has not been a device that realizes functions such as voice encryption, U disk data encryption, computer data encryption, and fax encryption on a telephone set, and there is no integrated data service encryption device that separates the machine card.

Embodiment 1

[0069] The machine-card separation type postal transmission encryption telephone system is composed of a certificate key management center, a UK secret card and a postal transmission telephone set. The certificate and key management center is an authoritative certificate and key distribution center, centralized management, and offline work; the UK secret card is connected to the postal telephone through the UK-secret card interface.

[0070] Wherein, the certificate key management center is composed of a user data backup server 101, a certificate and key management center server 102, a user data server 103, an operator terminal PC 104, and a central UK secret card 105 connected in sequence, as figure 1 shown.

[0071] Among them, the server 102 of the certificate and key management center completes the generation and distribution of the certificate through the operator terminal PC 104, and will configure the digital certificate, key and other data with the unique label of the...

Embodiment 2

[0092] The machine-card separation type postal transmission encryption telephone system is composed of a certificate key management center, a UK secret card and a postal transmission telephone set. Under the situation of not changing the certificate key management center and the UK secret card, this embodiment is a PSTN network plain phone, data encryption type digital telephone set. see Figure 4 Shown, described PSTN network plain language, data encryption type digital telephone set are by telephone handle 301, line control 302, ordinary telephone circuit 303, ARM central processing unit 307, MODEM 308, facsimile machine 309, facsimile data protocol conversion 310, U Disk interface 311, U disk and computer data area 312, UK-secret card interface 314, RS232 serial port 315, PC 316, LCD and keyboard 401 are connected to form. The difference between embodiment 2 and embodiment 1 is that, said PSTN network clear words, data encryption type digital telephone set do not have voic...

Embodiment 3

[0094] see Figure 5 As shown, the present embodiment 3 is a PSTN / IP type postal transmission telephone set; the difference between the present embodiment 3 and embodiment 1 is that the postal transmission telephone set is a PSTN / IP network type postal transmission encrypted telephone set, and the PSTN / IP Compared with the circuit of the PSTN type digital encryption machine, the circuit of the network type digital encryption machine has increased the part of the control function of the IP network interface; Figure 5 As shown, the PSTN / IP network type digital encryption machine is connected to the PSTN telephone office 320 and the Internet P network respectively; and an IP network control switch 501 and a network port 502 are added on the postal telephone; 503, then all business functions are realized through the Internet. Before the above-mentioned three kinds of business data enter the Internet 503, first all business data are encrypted by the ARM central processor 307 and t...

Abstract

The invention aims to provide a telephone-card separated mail encryption telephone system. The telephone-card separated mail encryption telephone system realizes comprehensive secret communication equipment with multiple functions in one machine and realizes encrypted transmission functions of comprehensive services of voice, U disk data, computer data, paperless fax data and the like on a PSTN network. The invention adopts the following technical scheme that: the telephone-card separated mail encryption telephone system consists of a certificate key management center, a UK secret card and a mail transmission telephone. The certificate key management center is a key management center for authorized certificate generation, distribution center, centralized management and off-line work. The UK secret card is connected with the mail transmission telephone through a UK secret card interface. The system has the advantages that the telephone-card separated mail encryption telephone solves the problem of simultaneously realizing encrypted transmission of the voice, the U disk data, the computer data and the fax data with one machine type, and can form various data encryption application model.

Description

technical field [0001] The invention relates to a communication security device, in particular to a machine-card-separated postal encryption telephone system. Background technique [0002] In today's world, the communication industry is developing rapidly, and various communication technologies emerge in endlessly. With the emergence of Internet technology, data transmission tasks basically give way to the Internet, and data transmission on the PSTN (Public Switched Telephone Network) network is less and less. [0003] However, the secure transmission of data on the PSTN network has its unique advantages. Since the PSTN network is a point-to-point communication, it will not be placed on a public server like the data transmitted on the Internet, and everyone can access it. It can only be transmitted between the sending and receiving parties, and other people cannot read its data, so the security is higher, and the chances of Trojan horse, virus infection and hacker attack are...
