Abstract
The invention discloses a method for decrypting, copying and pasting encrypted data. The method comprises the following steps: a service client is entered; the service client requests a service system to issue an encrypted authentication code; the service system issues a cipher text authentication code; the service client monitors and acquires the cipher text authentication code; the service client calls an SE decrypted cipher text; an SE returns plaintext information to the service client; and the service client pastes the plaintext information. According to the method of the invention, the safety element or other external equipment is adopted to perform authentication code decryption and automatic copying and pasting, which brings convenience to operation by users and improves the safety and convenience of transaction authentication.
Description
Technical field
The present invention relates to field of communication security, particularly a kind of deciphering of enciphered data copies method of attaching.
Background technology
Patent of invention (application number 201110378650.6) provides a kind of cloud to copy method of attaching, comprise cloud clone method and cloud method of attaching, described cloud clone method, comprise the following steps: client is obtained user ID and reproducting content, and described user ID and reproducting content are sent to server; Described server receives described user ID and reproducting content, by described user ID and reproducting content corresponding stored.Described cloud method of attaching, comprises the following steps: client is obtained user ID and paste operation; Described client sends the stickup request that comprises described user ID to server according to described paste operation; Described server is according to the described stickup acquisition request reproducting content corresponding with described user ID, and described reproducting content is handed down to described client.Above-mentioned cloud copies with cloud method of attaching and has avoided frequent input validation code, has improved the convenience of user's operation.But provide convenience to illegitimate client, in the unwitting situation of user, server can be intercepted and captured short message content, and unauthorized theft user's fund or sensitivity have valency information.
Summary of the invention
Technical problem to be solved by this invention is, for prior art deficiency, provides a kind of deciphering of enciphered data to copy method of attaching, when user's operation ease is provided, improves the fail safe of short message content.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of deciphering of enciphered data copies method of attaching, and the main implementation procedure of the method is as follows: encrypt data is monitored and obtained to service customer end; Service customer end calls SE decrypting ciphertext; SE decrypting ciphertext; SE returns to cleartext information to service customer end; Service customer end is pasted cleartext information.
Service customer end proceeds as follows: enter service customer end before monitoring and obtaining encrypt data; Service customer end requested service system issues the identifying code of encryption; Operation system issues ciphertext identifying code.
Service customer end is pasted after cleartext information, automatically performs follow-up business.
The present invention also provides a kind of deciphering of enciphered data to copy affixing system, comprising:
Service customer end: issue the identifying code of encryption for requested service system, monitor and obtain encrypt data, call SE decrypting ciphertext, and paste the cleartext information after SE deciphering;
SE: for decrypting ciphertext; For returning to cleartext information to service customer end.
Operation system: for issuing the identifying code of encryption.
Compared with prior art, the beneficial effect that the present invention has is: the present invention uses safety element SE or other external equipment, carry out the deciphering of short message content and automatically copy stickup, when user's operation ease is provided, improved the fail safe of short message content.
SE is the safety chip with hard encryption and decryption functions, may reside in recipient's identification module (SIM card), also may reside in SD card, also may reside in mobile phone terminal inside.
Brief description of the drawings
Fig. 1 is one embodiment of the invention method flow diagram;
Fig. 2 is the system configuration of one embodiment of the invention;
Fig. 3 is the flow chart that the inventive method is used at application scenarios.
Embodiment
As shown in Figure 1, symmetry or unsymmetrical key are set between operation system of the present invention and SE, for the encryption and decryption operation of cipher-text information, idiographic flow is as follows:
1. user enters service customer end and carries out related service operation;
2. if any short-message verification business, service customer end requested service system issues the short-message verification code of encryption;
3. operation system issues ciphertext short-message verification code;
4. mobile phone receives note and puts into note case;
5. ciphertext note is monitored and obtained to service customer end;
6. service customer end calls SE decrypting ciphertext;
7. SE returns expressly to service customer end;
8. service customer end is pasted cleartext information in frame to be entered;
9. service customer end carries out subsequent operation automatically.
As shown in Figure 2, service customer end must increase a module---SE communication module to the system configuration of one embodiment of the invention, in SE, must increase a module---decrypted program.Service customer end sends identifying code decoding request to the decrypted program of SE, decrypted program extracts decruption key, by the algorithm consulting with operation system, identifying code is decrypted, then return to decrypted result to background communication module and UI module to SE communication module, decrypted result is sent to operation system verification by background communication module, and UI module shows the plaintext after deciphering.
With the Fetion client on SE, mobile phone on mobile phone log on as example describe application scenarios, the flow chart of scene as shown in Figure 3:
1. user enters mobile phone Fetion client;
2. user clicks login " button ";
3. client is to Fetion operation system request short-message verification code (can be also the identifying code of client side HTTP mode, lower same) herein;
4. Fetion operation system generates short-message verification code, and is encrypted with 3DES algorithm (also can use other symmetric key algorithm at this, as aes algorithm);
5. Fetion operation system issues ciphertext short-message verification code;
6. mobile phone receives note and puts into note case; Ciphertext note is monitored and obtained to Fetion client simultaneously;
7. Fetion client is initiated request by the API of SE to SE, with decrypting ciphertext;
8. SE is decrypted ciphertext with 3DES algorithm (also can use other symmetric key algorithm at this, as aes algorithm, corresponding with cryptographic algorithm);
9. SE returns expressly to Fetion client;
10. Fetion client pastes cleartext information in frame to be entered;
11. Fetion clients send logging request from trend operation system at demonstration cleartext information in a flash, carry this identifying code in this request;
12. these identifying codes of operation system verification;
13. operation systems are returned to login response (after verification succeeds, normally login) to client.
Note:
In a, SE, must increase by an application program, to realize the deciphering of identifying code, and deposit decruption key;
B, implement process in, need user on cell-phone customer terminal, from operation system, to download key to SE so that operation system is carried out the encryption of identifying code with this key, and SE carries out the deciphering of identifying code with this key.
