Fig. 2 is the 3G mobile voice messaging encryption application of MiniUSB card; According to the actual demand of using, MiniUSB clip pin chip need provide suitable interface function to satisfy the realization of KMC's management software, user administration software, 3G mobile 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 realization through to the appropriate design and the corresponding control command of memory block can provide the basic access function of certificate, and can realize double certificate.
3 keys are to management interface: can be according to control command to multiple key to managing, right like temporary key, certificate key equity.Can confirm the unique corresponding relation of certificate key pair and certificate, and can verify.
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 summary (Hash) of password is compared, can prevent effectively that the disabled user from through tackling communication data, intercepting and capturing password.
The interface function that mobile phone end software uses MiniUSB clip pin 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 MiniUSB clip pin chip to provide is realized KMC's module, can realize functions such as certificate generation, certificate importing, certificate derivation, certificate revocation, distributing certificates revocation list.
This utility model major technique innovative point comprises:
1 hardware chip main control unit adopts SM1, SM2 and the SM3 cryptographic algorithm of examining through national Password Management office, is used for the 3G voice messaging and encrypts, and can effectively guarantee the reliability and the high efficiency of cryptographic algorithm.
The design of 2 self defined interfaces can be combined into an application system effectively with card, cell phone platform and PC platform, has reduced the difficulty of research and development, has improved the efficient of research and development, has expanded the platform of research and development.
3 adopt the software and hardware combining voice messaging to encrypt instead of pure software cryptography; Can use the key of true random number as encryption and decryption; And significant data is kept in the hardware, has guaranteed the fail safe of speech data, avoided pure software by the danger of decompiling or tracking; Hardware algorithm is more efficient than software algorithm, can guarantee calling quality, improves user experience.
