Embodiment
Contrast accompanying drawing and the present invention is further elaborated below in conjunction with embodiment.
Referring to Fig. 1 to Fig. 5, the present invention mainly solves the privacy problem after the cross-platform transmission of security information of portable terminal.
Fig. 1 is the structural representation of portable terminal (also can be mobile platform or other platforms, this paper only be example with the portable terminal), and Fig. 1 only shows mobile terminal structure related to the present invention, does not show that portable terminal only limits to illustrate module.Each functions of modules is described as follows:
Enciphering/deciphering module: be used for security information is carried out enciphering/deciphering.During encryption, be security information configuration secure identification and related password; By information is encrypted, even other people acquired information does not have decipherment algorithm can't obtain actual information yet.Cryptographic algorithm can adopt various cryptographic algorithm well-known to those skilled in the art, and for example DES, 3DES or DES+MAC, 3DES+MAC or the like also can adopt other cipher mode or Custom Encryption mode certainly.
Memory cell: be used for stored information, information as herein described, comprise such as subscriber identity information, address list, user's signing service information, various information such as user's application data, according to the display mode of information under the different mode (security schema and general mode) of portable terminal, information is divided into security information and unclassified information, wherein, unclassified information all can show under security schema and general mode, and security information can only show under security schema, for describing purpose clearly, at this, the memory location of security information in the memory cell is called the security information memory block, the memory location of unclassified information is called unclassified information storage area, and the user can enter password by the input security schema, and obtains the access right of security information memory block.It should be noted that, the alleged security information memory block of this paper does not show in memory cell a slice continuum that certain existence marks off specially as the security information memory block, and it is suitable for physically not existing and the situation of just dividing for the convenient notion of making of composing a piece of writing equally.
Information transmission/receiver module: be used for transmission/reception information.
Display module: be used for man-machine interaction and information and show.
As shown in Figure 2, when portable terminal is in security schema, its treatment step that increases a security information is as follows:
One, selects cryptographic algorithm: will provide cryptographic algorithm to select with menu or other forms of exchange interface, the cryptographic algorithm of acquiescence can be set for the user.
Two, encrypting module is encrypted information and password according to the cryptographic algorithm that the user selects;
Three, storage data: in the security information memory block of memory cell, preserve information data.
Fig. 3 is a message transmission schematic diagram between the different information platform, in this example, the information platform of transmitting-receiving both sides all is a portable terminal, wherein, portable terminal A is a transmitter side, portable terminal B is a receiver side, and the information of terminal A and B all comprises unclassified and security information two classes, i.e. unclassified information B_S1 and security information B_P1 on unclassified information A _ S1 on the terminal A and security information A_P1 and the terminal B; The information of terminal A is transferred to terminal B by modes such as storage card or Bluetooth transmission, and the information of terminal B constitutes as shown in Figure 4 like this.For terminal B, claim that security information A_P1 is transmitter side security information or opposite end security information; Security information B_P1 is the local terminal security information.
With terminal B is example, and the display mode of unclassified information A _ S1 and B_S1 is consistent, no matter still be that unclassified pattern can show at security schema;
When terminal B is in security schema, security information B_P1 can show; And security information A_P1 is not owing to be not local information, and for guaranteeing the fail safe of cross-platform information, security information A_P1 has related password, therefore if show this information, also must authentication password, and when having only authentication password correct, A_P1 could show.Can realize cross-platform protection like this to security information.
Fig. 5 is the flow chart that end message (comprise and maintaining secrecy and unclassified information) shows, its step is as follows:
One, starting terminal security schema need carry out password authentification and just can enter, if password authentification success then enter security schema, the authentication password that terminal is entered security schema is designated as PSW_1, is called security schema and enters password;
Two, read information record (as contact person, short message etc.); Information according to Fig. 4 constitutes, for unclassified information A _ S1 and B_S1, then directly show, for local terminal security information B_P1, terminal inner has the decrypting process (invisible to the user) behind the demonstration validation, portable terminal selects the decipherment algorithm of coupling to decipher automatically according to the cryptographic algorithm title, need not artificial participation.For the user, also be similar to direct demonstration.
Three, comparison password: for opposite end security information A_P2, because it has related password, should be designated as PSW_2 by the association password, system at first compares PSW_1 and PSW_2, if it is identical, then be proved to be successful, show this opposite end security information A_P2, if it is different, authentication failed then, do not show this opposite end security information A_P2, it should be noted that because PSW_2 is the encrypted message after encrypting, thereby when comparison, compare again after needing earlier the cryptographic algorithm that PSW_1 adopts and PSW_2 is same to be encrypted, can in secure identification, carry the cryptographic algorithm name information that opposite end security information and related password thereof adopt, encrypt with the cryptographic algorithm that makes things convenient for receiving terminal to select automatically to mate according to secure identification.After failing to show the opposite end security information, system will point out the user to continue to input password (promptly needing to input the related password of opposite end security information) to verify passing through security schema to enter the checking of password.If the password authentification mistake can't show this information; If the password authentification success then shows this opposite end security information.
Four, whether reset password: if password authentification (the related password authentification of opposite end security information) success for ease of the unified management of security information, can remind the user to unify password, the password reset mode is that password is removed or the password adjustment.Password is removed and is referred to the related password of removing the transmitter side security information, and like this, the user only need enter security schema can visit the opposite end security information that transmitting terminal sends as the security information of visit local terminal.The password adjustment then is that the user is the fail safe that still keeps the opposite end security information, do not cancel related password, and be that related password is adjusted into oneself password commonly used, during this opposite end of visit afterwards security information, still need to carry out twice above-mentioned password authentification, promptly security schema enters password authentification and the related password authentification of opposite end security information.
Usually, the user enters password at the security schema that obtains our terminal, by password authentification, just can obtain access right to security information, yet this only can guarantee the information privacy at local terminal, when security information is transferred to the receiver side terminal, the security schema that the receiver side terminal only need enter into local terminal just can obtain the access right of the security information of sending from transmitter side.The specific embodiment of the invention adopts the encrypting module that utilizes the transmitter side terminal to security information configuration secure identification and related password, the related password configuration here is included in the interpolation password of security information when not having the configuration association password and the adjustment password when disposing related password.
After receiver side terminal information receiver module receives the security information that transmitter side sends, judge that by the secure identification of security information it is a security information, thereby deposit it security information memory block of local terminal in, pass through secure identification, can guarantee that security information is invisible under general mode, the user extracts security information if desired, at first needs to utilize security schema to enter password and enters into security schema.Simultaneously, owing to being adopts the ciphertext storage, thereby can be that receiver side is learnt the cryptographic algorithm title that transmitter side adopts to security information and related password, to make things convenient for the deciphering of receiver side by secure identification.
And because the existence of related password even the receiver side terminal use enters the local terminal security schema, also still needs password authentification can extract the transmitter side security information with related password.Can guarantee security of cross-platform privacy information like this.On the other hand, the receiver side terminal also can be added related password for the former security information that belongs to local terminal, so that further improve the fail safe of security information.
The invention solves the problem that security information may be revealed after cross-platform transmission, can protect the safety of important information effectively.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
