Embodiment
Method and apparatus proposed by the invention is mainly used on the mobile communication terminal (for example mobile phone will be that example is illustrated with the mobile phone mainly below) of hand-hold type, and it mainly comprises the content of the following aspects:
1, the cryptographic technique in the mobile phone terminal: the mobile phone producer is provided with the above lock machine password of one group of 16 byte (reach as high as 1K byte or more than) for each mobile phone, password can be expressly or the ciphertext form deposit.If the ciphertext form is formulated concrete enciphering and deciphering algorithm by cell phone manufacturer, can increase the fail safe of password so to a certain extent, but can increase the complexity of system.Password should leave on the non-volatile memory chips such as FLASH, EEPROM of system, and does not allow to be placed in the SIM card.The modification of password and wipe the professional site of being authorized by cell phone manufacturer and finish, its access limit is formulated by manufacturer oneself.
2, crypto carrier technology:, dispose the crypto carrier (can be profiles such as card form, Wristwatch type or key button) of a band contact or contactless chip corresponding to each mobile phone terminal.Depositing in the carrier with the same password of corresponding mobile phone, can be that plaintext or ciphertext form are deposited.Carrier is controlled by the IC-card security mechanism the access limit of password as the IC chip, can be key authentication or other approved method.If crypto carrier is lost or damaged and can report the loss or repair to the site that manufacturer is authorized, new password is set for again mobile phone terminal and carrier by them for the situation of losing.
3, IC-card module for reading and writing:, need in every mobile phone terminal, increase a Card Reader chip in order to realize the separate type cipher authentication technique.Have a large amount of being used to read and write contact and contactless chip on the market, but contactless technology is development in future direction (as Philips company's " MF RC531 " family chip or a more microminiaturized product).Because these chips are very little, so they are very little to the size impact of mobile phone terminal.The course of work of card reading module is such: after system powered on, self check success back system prompt needed crypto carrier.If carrier exist system will activate card reading module read in the carrier unlocking pin and with terminal in the startup password deposited compare, as the then release success that conforms to, mobile phone enters normal holding state; As not conforming to or reading less than unlocking pin, mobile phone then still is in locking state.Do not allow all buttons of operating system at locking state, and sound out or the mode of other stealing passwords for malice repeatedly, also but triggering system is sent data alarm signal (as public security 110 alarm stations etc., the application number of seeing the inventor is 02153283.4 application for a patent for invention) automatically to the control centre that sets in advance.
4, the communication between terminal and the crypto carrier: can adopt contact or contactless communication modes between terminal and the carrier, comprehensively their pluses and minuses are considered, contactless mode is used in suggestion, the communication modes of present popular 13.56MHz for example, it follows ISO/IEC 14443 standards, and maximum communication distance is 10 centimetres.
The method that the present invention proposes is to realize on the basis of hand-hold type portable terminal, and the configuration of the portable terminal that has a crypto carrier of the present invention as shown in Figure 1.The startup password of the some memory cell in terminal (for example flash, EEPROM etc.) storage equipment, this password is with plaintext or encrypted test mode, the length of password depends on the capacity of the crypto carrier of separation, but the shortlyest should not be less than 16 bytes, the composition of password can be Arabic numerals arbitrarily, also can form, even can also mix by Arabic numerals and English alphabet or other character and form by any English alphabet; The cipher processing method of password is customized by manufacturer oneself.Modification to password need be satisfied certain authority, and also manufacturer terminal oneself is definite again for concrete security mechanism.Safety control module can be that hardware or software mode are realized, it is mainly used in to the protection of password with the authentication of crypto carrier etc.All is independently from function card reading module and safety control module on hardware and software with the mobile phone terminal part, and such design helps the maintenance and the upgrading of system.
To mainly introduce the verification process of the portable terminal that has crypto carrier below, concrete cipher authentication process is seen Fig. 2.After system powers on, it can search for and be connected to network automatically after its self check success, whether fail self-test is then given the prompting of being out of order, if connect unsuccessful then display reminding information and continued to connect by user's decision, successful then point out the wait crypto carrier on display unit.Microprocessor controller MCU will start card reading module crypto carrier will be carried out two-way authentication after the user provides crypto carrier, only at authentication success and have and read the password that just begins to read after the password authority in the crypto carrier, if need encryption and decryption then to finish by safety control module.MCU reads and also reads corresponding unlocking cipher immediately after the password in the carrier from memory cell and compare, if two password unanimities then allow to use all keys and the function (being in holding state) of terminal, allow card reading module and safety control module be in park mode simultaneously to reduce power consumption; If the inconsistent retry that then allows in stipulated number of password, system carries out self-locking or reports to the police by the mode of automatic warning after number of retries surpasses stipulated number.If self-locking state is all keys and the function of locking terminal then, then send alert data by communication module and RF circuit automatically to predefined control centre if need to report to the police by MCU, concrete data format is formulated by manufacturer terminal and control centre.
Crypto carrier that match with mobile phone, the type built-in contactless microelectronic chip, it can be the logical encrypt microelectronic chip card of any abnormity encapsulation, chip has non-volatile type memory cell, and size is not less than 16 bytes, is mainly used in to deposit the password that is used to start shooting.This password is one to one with the password in the mobile phone, and the password in each carrier all different (relation object of password and terminal is similar to the relation of key and lock), and random number is adopted in the password suggestion.Because carrier itself is an IC-card chip with higher-security, therefore must satisfy certain authority to the read-write of carrier password.For convenience the user carries in addition, the form that suggestion considers to use Wristwatch type (digital display, pointer-type all can, have clocking capability concurrently) or key button, little gadget etc. to be difficult for losing.
The technology of the present invention and method if be used on the mobile phone with gps satellite positioning function or LCS network positions function, then can be exerted one's advantage more; When illegal this kind of acquisition mobile phone person under can't the situation of release, attempt to call or when receiving and dispatching short message, just triggered the position that the automatic warning function of data type (application number of seeing the inventor is 02153283.4 the application for a patent for invention) police can be shown according to positioning function, in time arrest and buy the stolen goods people or the person of disposing of stolen goods, then involve and steal the criminal gang who robs mobile phone, more possible is, seek cheap people and again dare not buy of unknown origin booty mobile phone, thereby thoroughly blocked the market of booty mobile phone.
