Abstract
The encryption method based on mobile terminal data file of the present invention, pass through the dynamic authorization code of third party's acquisition for mobile terminal, the dynamic authorization code management client of file data user terminal loading is submitted to, the encrypting and decrypting management of dynamic authorization code is carried out to the file data of the mobile terminal.The invention constructs one can not be by third party's physical isolation terminal that account system can be contacted directly or can directly be attacked, and the dynamic authorization code by being obtained from this third party's physical isolation terminal, to complete the encrypting and decrypting Certificate Authority of account.Thus user is facilitated independently, it is easy to the mobile terminal data file on one's own initiative to complete the decryption application of dynamic authorization code encryption, and establish application technology specification of the dynamic authorization code in information cloud storage of complete set, user is facilitated to spread to multi-field safety applications, greater security is provided the user, more convenient practicality, multi-field applicable safe encryption authorization technology.
Description
Technical field
The encryption method based on mobile terminal data file of the present invention, relates generally to computer information data encryption technology
Field, synchronize the application of encryption safe management to file data in mobile terminal in particular with dynamic code encryption technology.
Background technology
Currently, when carrying out data storage, the method for generally use is clear-text way storage or used mobile terminal
The secured fashion that system carries is stored.Usually, its AES arranged using the system of acquiescence and key are to storage
Data on a storage medium carry out safe storage, or some concrete application uses its own defined algorithm and key to pin
To being stored using the data of itself.
For security standpoint, the safety measure of data with existing storage can realize a certain degree of safeguard protection.But
The degree that mobile terminal user participates in its data protection is inadequate.Due to existing methods popularity, the publicity of algorithm and latent
Key knowability, the security mechanism that either system carries still for application safety precautions, be all likely to occur
The risk that the data that user is stored in the case of unwitting are cracked, so as to cause secret or the privacy number on mobile terminal
According to leakage.The characteristics of due to cloud mode, data owner no longer safeguard the carrier of data storage, and user is regardless of which cloud of selection
Service provider must be to its complete trust.But in reality, the data of user, especially with the number of intelligent terminal collection
According to（Such as：Personal photo, communications records etc.）Often related to privacy, user is not intended to its completely entrusting to storage
Service provider.Lack effective data safety preventive means turns into one of most important reason for hindering cloud service to promote.
Existing such as 360 bodyguards, mobile phone house keeper etc., realize and prompt alarm to the intrusion detection of mobile terminal, but do not have
To the protection of file data after preventing from invading and steal by a kind of encryption technology；Although it is provided with password mould in open state
Formula, but further encipherment protection is not carried out to subscriber data；Although there is the encryption box mode to file data protection, do not have
Have and file data in encryption case is encrypted, and the static encryption pattern that user actively realizes is easy to be cracked；Especially
It is the file data that user uploads high in the clouds by mobile terminal, is yet not carried out encipherment protection.
Documents 1, mobile terminal and method, application number：201310692720.4, it is proposed that a kind of number of mobile terminal
According to security access mechanism, encrypted ones are independently set by user user, self establishment and functional module recommend two ways to enter
The selection of row encrypted ones, and write storage from the data of mobile terminal and read storage both direction and data are encrypted/decrypted
Security control, it is achieved thereby that the secure access of data.The problem of invention is present is that the autonomous setting code of user is easily simple
Easily crack, be not easy to remember if complicated, and be used as a kind of static encryption technology, the possibility cracked by people is bigger.
Documents 2, the encryption cloud storage method based on intelligent mobile terminal, application number：Although 201210098906.2
A set of credit mechanism is established, but it configures proprietary hardware encryption card and brought to user using inconvenience, and use quiet
State encryption mode, still escape the quagmire only easily cracked.
The content of the invention
The problem of present invention exists for above-mentioned encryption technology, it is proposed that total solution, using safe and secret degree
High dynamic code（That is dynamic authorization code of the invention）Convenience application of the technology in mobile terminal and cloud storage field.This hair
The bright encryption method based on mobile terminal data file, it is three patents of invention based on me formerly, one is, the individual person
The root service system of part certification, the patent No.：2011102160995, the second is, the side of dynamic authorization code is established in identity-based certification
Method, the patent No.：2014103040797, the third is, establish the unified dynamic authorization code system of business entity's account, the patent No.：
2014103039893, the specific computerized information field application on this three patent of invention technical foundation.
The encryption method based on mobile terminal data file of the present invention, for dynamic code encryption technology in mobile terminal pair
The application of file data encryption, has done brand-new Technology design, and its innovative technique realized value includes：First, establish unified
Dynamic authorization code applications client, facilitate user independently, it is easy to the data file on one's own initiative to complete dynamic authorization code
Encrypting and decrypting application；2nd, dynamic authorization code is realized to the mobile terminal Auto-matching that is encrypted in of data file, facilitates user one
Key encipherment protection data file security；3rd, by authorizing acquisition for mobile terminal dynamic authorization code, dynamic authorization code key has been prevented
The possibility being stolen；4th, dynamic authorization code is obtained by the certification of legal capacity Verification System, ensure that the method for dynamic authorization code
It is qualitative, improve the ability that dynamic authorization code technology participates in higher cryptographic security environmental applications；5th, add whole to application memory
Hold the authorization identifying requirement of special parameter, ensure that steal information can not cracking；6th, realized by multi-enciphering technology,
Improve the multiple protective dynamics of information；7th, application skill of the dynamic authorization code in information storage terminal of complete set is established
Art specification, facilitate user to spread to multi-field safety applications, provide the user greater security, more necks of more convenient practicality
Domain is applicable safe encryption authorization technology.
Whole dynamic authorization code application technology patent, includes entire series application technology Patent exploitation, everybody can join
According to other Patents of the series of the present inventor, it is explained herein.
The encryption method based on mobile terminal data file of the present invention, it is in dynamic authorization code client, increase encryption
Management module, encryption handling of the dynamic authorization code to mobile terminal storing card data file is realized, realize dynamic authorization code to moving
Dynamic terminal uploads the encryption handling of high in the clouds data file.
Relative to the other-end under the same dynamic authorization code account of user, including PC terminals, server terminal and movement
Terminal, the mobile terminal described in the present invention is reading end based on dynamic authorization code and encryption handling module is in same movement
In terminal, its encryption handling module binding configuration is in dynamic authorization code reading client.Because this application feature will be sent out
