Abstract
The invention discloses an asymmetrical mobile phone short message encryption method. The asymmetrical mobile phone short message encryption method sequentially comprises the following steps: secret key establishing and storing, addressor encrypting, addresser sending, addressee deciphering, short message content displaying and the like. Mutually independent public key and private key are established in the mobile phone, the public key can be uploaded to the server, when sending short message, the addresser only needs to send the short message content and does not need to send the secret key at the same time. Therefore, even if the secret text content is intercepted, a mobile operator which transmits the secret text content just knows the encrypted character, genuine content of the short message cannot be analyzed, the genuine secretive goal is achieved, privacy degree of the short message is improved, secretive degree is improved, and private and confidential information of users are effectively protected. The asymmetrical mobile phone short message encryption method takes up little mobile phone resource.
Description
[technical field]
The present invention relates to the mobile phone application software method, particularly a kind of asymmetric method for encrypting mobile phone short message.
[background technology]
Mobile phone has become indispensable important communication tool in people's work and the life.Adopt mobile phone to carry out the important communication modes that note sends has become people, but the content that adopts mobile phone to send undue secret or privacy tend to cause trouble.Therefore, in the prior art, also with the Encrypted short message function, the note that sends is encrypted in some high-end mobile phone, but all is the symmetric cryptography mode that adopts in the present Encrypted short message function, ciphertext sends with secret key.After this mode ciphertext was intercepted and captured, content also just disclosed thereupon, and especially the ciphertext secret key will be accepted and transmission through mobile operator certainly, and content is easy to be disclosed, and confidentiality is not strong.
[summary of the invention]
Purpose of the present invention solves the problems of the prior art exactly, proposes a kind of asymmetric method for encrypting mobile phone short message, can't be cracked the ciphertext content even ciphertext intercepts and captures also, can improve privacy degrees, effectively protects user's privacy and confidential information.
For achieving the above object, the present invention proposes a kind of asymmetric method for encrypting mobile phone short message, may further comprise the steps successively:
Set up and preserve the secret key step: note both sides have all set up public spoon and private spoon, and the public affairs spoon is uploaded onto the server, and private spoon is kept at local repository;
Sender's encrypting step: the sender inquires about the public spoon that obtains corresponding addressee from server, utilizes the public spoon of addressee to carry out short message content and encrypts;
Sender's forwarding step: the note after the sender will encrypt sends;
Addressee's decryption step: after the addressee receives the ciphertext note, utilize local private spoon to carry out the short message content deciphering;
The short message content step display: the short message content after the deciphering is read by the addressee by screen display.
As preferably, specifically may further comprise the steps successively:
A) the note both sides set up respectively separately private spoon and public spoon;
B) the note both sides are left private spoon in local repository respectively;
C) the note both sides upload onto the server the public spoon of oneself respectively;
D) sender selects the addressee and inquires about public spoon that obtains the addressee from server;
E) judge whether the note that needs to send is long SMS, if be long SMS, then enters f) step; If not long SMS, then enter i) step;
F) content of long SMS being carried out segmentation disassembles;
G) utilize addressee's public spoon that segmented content is encrypted;
H) assembly unit is carried out in each segmentation after will encrypting;
I) utilize addressee's public spoon that short message content is encrypted;
J) sender sends the ciphertext note;
K) addressee receives the ciphertext note;
L) judge whether the ciphertext note that receives grows the ciphertext note, if for long ciphertext note, then enter m) step; If not long ciphertext note, then enter o) step;
M) utilize private spoon segmentation decrypting ciphertext note;
N) the ciphertext note with the segmentation deciphering is assembled into long SMS;
O) utilize private spoon decrypting ciphertext note;
P) show short message content.
When as preferably, described e) judging whether to be long SMS in the step, if contain Chinese character in the short message content, then more than or equal to X
1The content of individual character is judged as long SMS; If do not contain Chinese character in the short message content, then more than or equal to X
2The content of individual character is judged as long SMS.
As preferably, described X
1=15～19, X
2=50～56.
As preferably, described j) go out outside the short message content in the ciphertext note that the sender sends in the step, also include the note marking head, the note marking head records the version information of Encrypted short message type and encryption key.
As preferably, described j) short message content that shows in the step is stored in the local private data of the addressee storehouse.
As preferably, described j) short message content that shows in the step utilizes the twinkle SM pattern to show, gives up immediately after the reading, does not have draft in the mobile phone.
Beneficial effect of the present invention: the present invention sets up separate public spoon and private spoon at mobile phone; and public affairs spoons uploaded onto the server; the sender is when sending note; only need to send short message content; do not need to send simultaneously secret key; like this; even the character after the mobile operator that send content also only knows encryption is intercepted and captured or transmitted to the ciphertext content; and can not parse the real content of note; reached real purpose of maintaining secrecy; improved the secret degree of note, improved privacy degrees, effectively protect the user privacy and confidential information.It is few that this method takies mobile phone resources.
Feature of the present invention and advantage will be elaborated by reference to the accompanying drawings by embodiment.
[description of drawings]
Fig. 1 is the flow chart of the asymmetric method for encrypting mobile phone short message of the present invention.
[embodiment]
Asymmetric method for encrypting mobile phone short message may further comprise the steps successively:
A) the note both sides set up respectively separately private spoon and public spoon;
B) the note both sides are left private spoon in local repository respectively;
C) the note both sides upload onto the server the public spoon of oneself respectively;
D) sender selects the addressee and inquires about public spoon that obtains the addressee from server;
E) judge whether the note that needs to send is long SMS, if be long SMS, then enters f) step; If not long SMS, then enter i) step; When judging whether to be long SMS, if contain Chinese character in the short message content, then more than or equal to X
1The content of individual character is judged as long SMS; If do not contain Chinese character in the short message content, then more than or equal to X
2The content of individual character is judged as long SMS; X
1=15～19, X
2=50～56;
F) content of long SMS being carried out segmentation disassembles;
G) utilize addressee's public spoon that segmented content is encrypted;
