Below in conjunction with Figure of description the embodiment of the invention is described in detail.
Embodiment one:
As shown in Figure 1, be the embodiment of the invention one short-and-medium message-sending method schematic diagram, said method comprising the steps of:
Step 101: the user sends the request of encryption to SIM card, and carry identifying code in described encryption request by the menu option of mobile terminal screen output.
The effect of described encryption request is that the user asks the SIM card short message to be encrypted.
In this step, SIM card has the STK application function of encrypting short message, when the user calls this STK function, needs the input correct pass code, and for example, the PIN code of input SIM card is as identifying code.
Step 102:SIM card carries out authentication according to described identifying code to the user, when authentication is passed through, and execution in step 103; Otherwise refusal is carried out the short message secure service.
Step 103:SIM card is encrypted the short message after obtaining encrypting to the short message of user's input.
In the present embodiment, the user can write short message before sending the request of encryption, and the short message that writes is carried in the described encryption request; The user also can write short message after SIM card is passed through user's authentication.
Step 104:SIM card sends the short message after encrypting.
Particularly, SIM card can be by calling the short message after SEND SMS order sends encryption.
Scheme by step 101～step 104, to user's authentication by the time short message that the user is write carry out encrypting and transmitting, guaranteed the fail safe of the short message that user that SIM card is received writes, simultaneously, short message after SIM card will be encrypted sends, make that short message has improved the short message transmission process safe with the transmission of ciphertext form in the process of transmitting.
Each step to the embodiment of the invention one is described in detail below.
In traditional short message transmission, reception programme, the short message that sends and receive should be stored in the 6F3C file area, but in present embodiment one, SIM card is before the short message that sends after encrypting, in the short message after encryption encryption identification is set, is used to represent that this short message is the short message after encrypting.For example, the content by designated identification bits in the short message head of short message determines whether it is to encrypt short message, if designated identification bits is 0, the short message that expression sends is common short message, if designated identification bits is 1, encrypts short message during short message that expression sends.
Need after SIM card sends SMS message the short message that sends is judged at every turn,,, the short message that has sent is deposited in the 6F3C file area then according to traditional process if the designated identification bits content is 0; If the designated identification bits content is 1, then the short message that will send deposits in the 6FB0 file area.In the present embodiment, the 6FB0 file area is the privately owned file area in the SIM card, and its authority is set to: only allow by the STK in the SIM card content in the privately owned file area to be operated.Certainly, present embodiment also be not limited to set other file area as privately owned file area.
After the short message that transmitting terminal will send deposited privately owned file area in, the STK function of SIM card provided two kinds of modes that short message is encrypted in destruction for the user: auto-destruct mode and manual destruction mode, and these two kinds modes of destroying the encryption short messages are as follows:
The auto-destruct mode:
When the user selects the auto-destruct mode by the STK menu, need be provided with one first and set duration, as 30 minutes.After the affirmation, SIM card is judged the short message after whether privately owned file area has the encryption that has sent, if have, the transmitting time of the short message after the encryption of then determining to have sent, and pick up counting by the system clock of SIM card, after transmitting time one when setting duration and arriving, the short message that has sent is emptied, the full content that is about to encrypt short message resets to " FF......FF ".
Manual destruction mode:
When the user selects manual destruction mode by the STK menu, SIM card can represent the encryption short message that is stored in the privately owned file area to the user with the form of short message list, the user selects wherein certain bar short message and when confirming, promptly sending the short message that carries Short Message Identifier empties when asking, find out short message in the privately owned file area of SIM card and empty the short message of asking appointment, and the short message that finds out emptied, the full content that is about to encrypt short message resets to " FF......FF ".
In step 103, SIM card is carried out method of encrypting to short message and is included but not limited to following method:
Body matter in the short message breath of the at first definite user's input of SIM card, and described body matter is converted to character string according to the Unicode table of comparisons, then, SIM card is by calculation function of self and data encryption standard (DES) algorithm that is preset at the SIM card bottom, character string after the conversion is encrypted another character string after obtaining encrypting.Below by concrete example ciphering process in the present embodiment is described.
The form of the common short message that writes down in the 6F3C file area is by GSM11.11, GSM03.40 and GSM04.11 normalized definition, and the common short message of GSM is made up of the short message data head of 36 bytes and content of short message two parts of 140 bytes.Comprised sender's number, short message service center's number, transmitting time in the short message data head, read/information such as read states not.No matter content of short message is English content or Chinese content, can be converted into digital coding according to the Unicode table of comparisons, all corresponding 4 unique bit digital of arbitrary Chinese character or character.The content of short message that transmits in network in actual process of transmitting is 2 system form data of these digital coding just also.The concrete form of supposing a short message is:
000891683108100005F02411A1139100000010008807090515470237828e8ca43f7d832FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
Wherein, the content of this short message numeral from front to back is:
00: the state of representing this short message is " not reading ", if 01 expression " reading ".
0891683108100005F0: expression short message service center number.
24: expression short message parameter.
11: expression short message source numbers figure place, i.e. the phone number figure place of short message transmit leg.
A1: expression TON/NPI.
13910000001: expression short message source numbers, promptly the phone number of short message transmit leg is 13910000001.
00: expression PID.
08: expression DCS, unicode.
90709051547023: expression short message transmitting time, in 09 on July 9,15: 45: 7, the time zone is 23.
7828e8ca43f7d832 is a content of short message, and LV form, unicode coding, all the other F represent that content of short message is empty.
In the step 103 content of short message is encrypted, promptly 7828e8ca43f7d832 is encrypted, its ciphering process is: 7828e8ca43f7d832 is converted to hexadecimal value with content of short message, obtain 37383238653863613433663764383332, with the DES algorithm to the character string that is converted to after obtaining encrypting after hexadecimal value is encrypted be: 5041a5d06937f8f73f87e68a0e7d2810, the character string that obtains after the encryption is the content of short message of the encryption short message of transmission.
In present embodiment one, behind the short message after the SIM card transmission is encrypted, receiving terminal need receive the short message after the encryption, and specific practice is:
SIM card is decrypted the short message after obtaining deciphering after receiving short message after the encryption to the short message that receives.Receive the reading request of user's transmission when SIM card after, according to the identifying code that carries in the request of reading the user is carried out authentication, after authentication was passed through, the short message after SIM card will be deciphered was exported to the user, at this moment, the end to end security process of transmitting of short message finishes.
Embodiment two:
The embodiment of the invention two provides a kind of method for receiving short message, as shown in Figure 2, the SMS processing in the present embodiment two can be in embodiment one, after SIM card sends and encrypts short message, the SMS processing of short message receiving receiving end also can be a SMS processing independently.
The method of the embodiment of the invention two may further comprise the steps:
The short message after the encryption is received in step 201:SIM clamping.
In this step, in order to distinguish the common short message of storage and to encrypt short message, present embodiment also can be divided two file storage zones, be similar to the scheme of embodiment one, wherein, the 6F3C file area is stored normal short message, and the 6FB0 file area is the privately owned file area in the SIM card, and its authority is set to: only allow by the STK in the SIM card content in the privately owned file area to be operated.Certainly, present embodiment also be not limited to set other file area as privately owned file area.
Set up a cover event set between portable terminal and the SIM card, when a certain incident in the event set takes place, portable terminal will use incident download mechanism (Event Download) to transmit event details to SIM card.Short message reception incident is exactly in the event set, when portable terminal receives short message, the short message that receives can be stored into the 6F3C file area, and with this event notice SIM card.SIM card detects the designated identification bits in the short message that receives, if designated identification bits is 0, the common content short message is carried out according to normal flow during the expression short message; If designated identification bits is 1, during the expression encryption identification, determine that then the short message that receives is the short message after encrypting.When SIM card determines that the short message that receives is a short message after encrypting, this short message is copied to the 6FB0 file area, and the content of this this short message in the 6F3C file area changed into " this short message is for encrypting short message; please read " in SIM card is encrypted the STK application function of short message, but in the 6F3C file area, keep the content of the short message data head of this short message.
The short message that step 202:SIM card docking is received is decrypted, the short message after obtaining deciphering.
SIM card is decrypted the character string in the short message that receives by calling the DES decipherment algorithm, the character string after obtaining deciphering, and the character string after will deciphering according to the Unicode table of comparisons is converted to the short message body matter.
Content in the short message of supposing to receive be according among the embodiment one with the DES algorithm to being converted to the character string after obtaining encrypting after hexadecimal value is encrypted: 5041a5d06937f8f73f87e68a0e7d2810, then in this step, be converted into 7828e8ca43f7d832 according to the DES inverse operation, and obtain the short message body matter by the Unicode table of comparisons.
After the reading request that the user sends is received in step 203:SIM clamping, the user is carried out authentication according to the identifying code that carries in the request of reading.
When the user wishes to read the encrypt file of storing in the 6FB0 file area, need to send the request of reading by the STK menu, and input validation sign indicating number (as: PIN code).
Step 204:SIM card verifies that to user's identity after authentication was passed through, the short message after SIM card will be deciphered showed to the user; Otherwise refusing user's is read and is encrypted short message.
In this step, when the user read short message after the deciphering, SIM card was not read the state of described short message by reading to be revised as.
With the embodiment of the invention one similarly, in the present embodiment two, the STK function of SIM card provides two kinds to destroy the modes of encrypting short messages for the user: auto-destruct mode and manual destruction mode, these two kinds to destroy the modes of encrypting short messages as follows:
The auto-destruct mode:
When the user selects the auto-destruct mode by the STK menu, need be provided with one second and set duration, as 45 minutes.After the affirmation, SIM card judges whether stored the short message of state for having read in the privately owned file area, if have, then SIM card determines that state is the reading time of the short message read, when the second setting duration after described reading time arrives, state is emptied for the short message read, and the full content that is about to encrypt short message is set to " FF......FF "; Otherwise SIM card can be encrypted at certain bar next time and be picked up counting when short message is read, and arrives after 45 minutes short message to be emptied.
Manual destruction mode:
When the user selects manual destruction mode by the STK menu, SIM card can represent the encryption short message that is stored in the privately owned file area to the user with the form of short message list, the user selects wherein certain bar short message and when confirming, promptly sending the short message that carries Short Message Identifier empties when asking, find out short message in the privately owned file area of SIM card and empty the short message of asking appointment, and the short message that finds out emptied, the full content that is about to encrypt short message resets to " FF......FF ".
