Embodiment
Like Fig. 1,2, shown in 3; USB interface-based facsimile data encryption system; Comprise facsimile machine and the facsimile machine circuit that mainly constitutes that is connected with facsimile machine by man-machine exchange interface, facsimile coding, encryption and decryption module; Also comprise the USBKEY encrypting module; Said USBKEY encrypting module one end is connected with the encryption and decryption module of facsimile machine circuit, and the USBKEY encrypting module other end is connected with facsimile machine through USB interface, and two facsimile machines that possess the USBKEY encrypting module are realized enciphered facsimile communications through the PSTN network.
The USBKEY encrypting module need provide suitable interface function to satisfy the realization of KMC's management software, user administration software, PSTN facsimile machine encryption software function.The main interface function that need provide comprises: SM1/SM2/SM3 algorithm interface, certificate management interface, key are to management interface, true random number interface, password management interface.
The concrete design of MCU is following:
1 SM1/SM2/SM3 algorithm interface: according to practical application, on the canonical algorithm interface, increase custom parameter, make algorithm invokes more flexible, easy, and use more extensive.
2 certificate management interfaces:, the basic access and the authentication function of certificate can be provided through realization to the appropriate design and the corresponding control command of memory block.
3 key management interface: can manage multiple key according to control command, like root key, Device keys, session key etc.Can pass through root key Authentication devices key, adopt Device keys protection session key.
4 true random number interfaces: the true random number that can generate and return designated length according to control command.
5 password management interfaces: can verify the password that upper layer software (applications) sends, and the password verification mode is designed, the eap-message digest of password is compared, can prevent effectively that the disabled user from through tackling communication data, intercepting and capturing password.
The interface function that facsimile machine end software uses the USBKEY crypto chip to provide is realized the encryption and decryption module, can realize functions such as certification authentication, authentication, integrity verification, key change, symmetrical encryption and decryption.
The interface function that PC end software uses the USBKEY crypto chip to provide is realized KMC's module, can realize functions such as certificate generation, certificate importing, certificate derivation, certificate update.
Operation principle:
In the utility model; The USBKEY encrypting module is responsible for the generation of random key, and the function realization of SM1, SM2 and SM3 cryptographic algorithm and the storage of certificate etc. are through self-defining password interface; Offer software encryption and decryption module invokes, accomplish functions such as authentication and encryption and decryption.The facsimile data of facsimile transmission side; Handle through encrypting module; Generate enciphered data, through transmitting on the PSTN channel, the recipient receives ciphered data; Enciphered data is deciphered and in local facsimile machine, print through deciphering module, thereby realize the facsimile encryption function on the PSTN channel.
