Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

With reference to Fig. 1, mobile phone signature demo plant of the present utility model by cell phone platform 3 and in mobile phone additional safety function module 1, and SIM/UIM card 2 is formed.This safety function module 1 is made up of microprocessor chip 11 and thick-film interconnection 12, store signature, checking in the microprocessor chip, key and the relative program encrypting, decipher, and be provided with the public key calculation coprocessor, to finish in Information Signature, checking the related operation in the encryption and decryption processing procedure.This microprocessor chip places on the thick-film interconnection, and on thick-film interconnection, draw the corresponding circuit tie point of SIM/UIM deck and SIM/UIM card input and output contact with cell phone platform, by these circuit tie points make microprocessor chip respectively with cell phone platform and SIM card/UIM card connection, finish communicating by letter of safety function module 1 and cell phone platform 3 and SIM/UIM card 2 respectively by the SIM/UIM deck, finish encryption to information, deciphering, digital signature, signature verification and the storage of program, data.

With reference to Fig. 2, the microprocessor chip 11 of the utility model safety function module respectively with thick-film interconnection on first tie point 13 of drawing link to each other with second tie point 14, and first tie point 13 by thick-film interconnection is connected with input and output contact on the cell phone platform SIM/UIM deck, and second tie point 14 by thick-film interconnection is connected with the input and output contact of SIM/UIM card 2.

With reference to Fig. 3, Fig. 4 and Fig. 5, the utility model safety function module leads to and SIM/UIM card input and output contact tie point 14 in the one side of thick-film interconnection 12, and microprocessor chip 11 is connected with its tie point 14.This microprocessor chip 11 places on the thick-film interconnection 12, is encapsulated as bucking ladder shape or square shape.The another side of thick-film interconnection 12 is provided with the circuit tie point 13 with the input and output contact of cell phone platform SIM/UIM deck, and these circuit tie points are communicated with by thick-film interconnection with the corresponding input and output pin of microprocessor chip 11.

With reference to Fig. 6, Fig. 7 and Fig. 8, the syndeton of the utility model and cell phone platform and SIM/UIM card is that safety safety function module and the existing SIM/UIM card grafting of mobile phone are one, inserts on the SIM/UIM deck in the mobile phone again.The grafting of safety function module and SIM/UIM card is not have at SIM/UIM card 2 to have the position of circuit to offer dovetail groove 21 or square opening, and there is the one side of output contact to open minor face into dovetail groove at the SIM/UIM card, and another side is opened the long limit into dovetail groove, and the long limit of this dovetail groove and the length of minor face are consistent with the bucking ladder of microprocessor chip 11.Safety function module 1 is close to SIM/UIM card 2 during grafting, it is chimeric that bucking ladder microprocessor chip 11 on the safety function module is inserted in the dovetail groove of SIM/UIM cards in 21, and second tie point 14 of the thick-film interconnection one side of safety function module is connected with connecting circuit on the SIM/UIM card.The SIM/UIM card that will have safety function module again inserts on the SIM/UIM deck in the mobile phone, makes the thick-film interconnection another side of safety function module connect electricity 13 and is connected with cell phone platform, by safety function module cell phone platform and SIM/UIM clamping is led to.Because the film two sides of safety function module is respectively equipped with the tie point with mobile phone SIM/UIM deck and SIM/UIM card, thereby the dismounting of this safety function module does not influence the operate as normal of mobile phone.

During work, the communication of 3 pairs of SIM/UIM cards 2 of cell phone platform is all carried out transparent forwarding by safety function module 1, and promptly the SIM/UIM cartoon is crossed safety function module and finished communication to cell phone platform, but guarantees not influence the function of original mobile phone and SIM/UIM card 2.

This safety function module as required to the information of communicating by letter between cell phone platform and the SIM card/UIM card encrypt, deciphering, digital signature and signature verification, transmit again after finishing arbitrary operation wherein.

This safety function module also can be directly and cell phone platform communicate, and the SIM/UIM card expanded application function of utilizing cell phone platform to provide increases application program in mobile phone, wherein a kind of possible application provides the STK extender, finishes encryption, deciphering, signature and signature verification to cell phone platform transmitting-receiving short message.
