Description
Technical field
The present invention relates to technical field of data transmission more particularly to the safety methods of a kind of key and ciphertext separated transmission.
Background technique
Mobile internet era, instant message applications have very important effect in today of internet high speed development,
All kinds of communication applications softwares have great convenience for the user between exchange.Internet user cannot centainly lack when installing software
This instant message applications also takes up more so its reflected commercial value of institute also becomes increasingly conspicuous in Internet communication
Come more important position, the instant message applications user resources in China are very huge, and current instant chat software is in function
On also become increasingly abundant.The a large amount of important individual of user or job information data are all exchanged by instant message applications, while band
Carry out information problem of data safety.Country is to network information security pay attention to day by day now, user to personal data or information increasingly
Pay attention to.
Most of communication applications software all merely provides the function of user information exchange currently on the market, to user information
Safety but without enough attention.User sends important or while being related to private data by communication applications software and does not protect effectively
Maintaining method has Railway Project: 1, the mobile phone terminal of file data or the end PC are stored with clear-text way, device losses or disease
Malicious wooden horse is easy to get personal data.2, file data is easy to be stolen in transmission process.It is logical in third party simultaneously
It interrogates there are clear text copy on software application server, data storage is dangerous for users for phase.3, when recipient obtains file
There is no password or other modes certification, causes file that can not prevent file content from leaking when accidentally sending out.4, the file sent out cannot
Control frequency of reading and the effective time of other side.For this purpose, we have proposed the safety methods of a kind of key and ciphertext separated transmission.
Summary of the invention
The invention proposes the safety methods of a kind of key and ciphertext separated transmission, to solve to propose in above-mentioned background technique
The problem of.
The invention proposes the safety methods of a kind of key and ciphertext separated transmission, include the following steps:
S1: selection needs the file data encrypted, and by corresponding technology either application software, will be on mobile phone either PC
The file data for needing to encrypt carries out encryption storage, and encrypted file data is shown on platform, in case user looks into
It sees；
S2: user chooses the file data to be shared, and demand is transmitted to mentioning for file data by the program chains of platform
Supplier, and user needs to input password read, effective time, effective degree to program chains；
S3: after program chains extract data, file data being encrypted with password read, and " effective time " set by user and
The data of " effective degree " are encrypted, and file is then written in encrypted file and setting data together；
S4: and then send the sharing mode that the file in S3 is selected by user；
S5: user clicks after receiving file and opens file, and program chains will identify the encryption file and recipient is prompted to use
Family inputs password or password；
S6: password or password are informed recipient user by other means by program chains, after user receives password or password,
Password or password are inputted, program chains are set by password or password decryption setting data and file according to sender user
" effective time " and " finite number of time " show file, user is watched by reading equipment, and reads the setting of equipment domestic demand
There is the dedicated APP in seven continents；
S7: the file that user is checked, after " effective time " and " effective degree " of reading file reaches setting value, file will
It is automatically deleted destruction.
Preferably, the encryption in S1 uses national standard SM4 algorithm.
Preferably, the sharing mode in S4 is specially QQ, wechat, mail either other communication modes.
Preferably, the reading equipment in S6 is specially smart phone or computer equipment.
The safety method of a kind of key and ciphertext separated transmission proposed by the present invention, beneficial effect are:
1, the file of the key and the safety method of ciphertext separated transmission is encrypted when sending, and solves user file transmission process
The middle safety problem that there is eavesdropping or divulge a secret；
2, the key and the safety method of ciphertext separated transmission need password or password authentication when using file, solve user
Accidentally hair or sending object mistake and cause file content to be divulged a secret problem；
3, the key and the safety method of ciphertext separated transmission efficiently solve user's vital document and are stored in third-party application clothes
It divulges a secret or steals secret information problem present on business device；
4, the key and the safety method of ciphertext separated transmission are lost in user mobile phone or terminal device not will lead to vital document
Data information is divulged a secret.
Detailed description of the invention
A kind of position Fig. 1 flow chart of key and the safety method of ciphertext separated transmission proposed by the present invention；
A kind of position Fig. 2 encryption flow figure of key and the safety method of ciphertext separated transmission proposed by the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to 1-2, the invention proposes the safety methods of a kind of key and ciphertext separated transmission, include the following steps:
S1: selection needs the file data encrypted, and by corresponding technology either application software, will be on mobile phone either PC
The file data for needing to encrypt carries out encryption storage, and encrypts and use national standard SM4 algorithm, and by encrypted file data
It is shown on platform, in case user checks；
S2: user chooses the file data to be shared, and demand is transmitted to mentioning for file data by the program chains of platform
