Description
Technical field
The present invention relates to a kind of mail encryption methods, in particular to a kind of to be based on time and space communications content transmission side
Method.
Background technique
Information-technology age is arrived, and instant communicating system is increasingly various, powerful；But in instant messaging for user
The safety and secret protection of the mail and chat content that are transmitted do not obtain enough attention, the user of most communication system
Secret protection and communication security also all only rest on user account number level, for the safety of data in the transmission itself and reliably
Property be not affected by attention always, once the account number of user is stolen, that is, face the personal secrets problem such as leakage of information；At this point, data pass
Defeated safety and reliability becomes the important method of protection privacy of user；Binding time and space, and in data structure and
Transportation level carries out rigorous Encryption Algorithm, is the important method for realizing this target.
Summary of the invention
The object of the present invention is to provide one kind to be based on time and space communications content transmission method, realizes that communications content is passing
Holding in close confidence during defeated reaches the characteristic of data transmission, the anti-modification in storing process and strong impact resistant, final to realize
Secret protection to user information safety.
The object of the present invention is achieved like this：One kind being based on time and space communications content transmission method, including following
Step：
S1 edits mail：Sender according to the word content of self-demand editor's mail, can uploading pictures, background sound may be selected
It is happy；
S2 reads letter time conditions：The time of mail opening is arranged in sender according to demand, and addressee is only at defined time point
Mail can be just opened afterwards；
S3 reads letter steric requirements：The spatial position of mail opening is arranged in sender according to demand, and addressee must be in regulation space
Position can just open mail；
S4, which is read, casually enables condition：Password is arranged to mail in sender, and is encrypted using the irreversible encryption mode of MD5, receives
Part people is received to after mail, it is necessary to input correct password, can open mail；
S5 time, space, content and the password chain of rings encrypt：After sender has edited communications content and reading condition, according to outbox
Readding for people's setting casually enables, and system will read letter time conditions and store according to casually order progress DES reversible encryption is read into database；
System will read letter steric requirements and store according to casually order progress DES reversible encryption is read into database；System is by the content of mail
Progress DES reversible encryption is casually enabled to store into database according to readding；It reads casually to enable and be additionally stored in server in itself；
S6 casually enables a chain of decryption time, space, content according to readding：When readding for addressee's input casually enables MD5 irreversible encryption
The data of the sender stored in data comparison database afterwards read after casually enabling MD5 irreversible encryption, after exact matching again
The reversible decryption for carrying out time, space, content is casually enabled according to readding before irreversible encryption, then is judged whether addressee meets and read
The letter time shows communications content after readding the condition in letter space.
It is further limited as of the invention, S1 edits mail and is specially：
S11：Sender carries out the copy editor of communications content by input method, can be can choose in mail with uploading pictures
The background music of mail keeps the expression-form of communications content more diversified.
It is further limited as of the invention, S2 reads letter time conditions and is specially：
S21：The time of mail is opened, when not reaching specified time node, addressee can not open mail and check content, with clothes
It is engaged in subject to the device time, to guarantee that the time reference standard of sender and addressee are consistent.
It is further limited as of the invention, S3 reads letter steric requirements and is specially：
S31：The spatial position of addressee, addressee must carry out mail opening in the designated space place selected by mail, consult,
System addressee's space address is compared with mail address by LBS technological means, space encrypt apart from design error
Value can be set, and set error amount as 5-15M, if mail can be checked, letter otherwise can not be opened in regulation spatial dimension
Part.
It is further limited as of the invention, S4, which is read, casually enables the condition be specially：
S41：Password encryption is arranged to mail in sender, and addressee is received to after mail, it is necessary to input correct password, ability
Enough triggerings read letter time conditions, read letter steric requirements.
It is further limited as of the invention, S5 time, space, content and the password chain of rings are encrypted as：
S51：Password encryption, system carry out cryptographic calculation to the casually order of readding that sender is arranged using the Encryption Algorithm of MD5, should add
Close algorithm belongs to irreversible encryption；
S52：Read letter time conditions encryption, system according to read casually enable using des encryption algorithm to read letter time conditions carry out can
Reverse encryption carries out storage safeguard protection to letter time conditions are read；
S53：Read letter steric requirements encryption, system according to read casually enable using des encryption algorithm to read letter steric requirements carry out can
Reverse encryption carries out storage safeguard protection to letter steric requirements is read；
S54：Content-encrypt, system uses des encryption algorithm to carry out reversible encryption to communications content according to casually order is read, to mail
Content carries out storage safeguard protection.
It is further limited as of the invention, S6 is according to casually order chain of rings decryption time, space, content is read：
S61：Decryption relies on, and reads letter time conditions, reads the reversible decryption password of DES of letter steric requirements, communications content dependent on readding
Casually enable；And readding for system storage casually enables as the irreversible data of MD5；So only readding for addressee's input casually enables MD5
The data of the sender stored in irreversible comparing database read after casually enabling MD5 irreversible encryption, exact matching
The reversible decryption for carrying out time, space, content is casually enabled further according to readding before irreversible encryption afterwards；
S62：It after casually order is correctly read in addressee's input, then matches and reads letter time conditions, read letter steric requirements, can show letter
Part content.
Compared with prior art, the beneficial effects of the present invention are for the maximum protection of user data privacy；Even if service
Device, source code, the exposure of database whole will not reveal the communications content of user.
Detailed description of the invention
Fig. 1 is data encryption flow diagram in the present invention.
Fig. 2 is data deciphering flow diagram in the present invention.
Specific embodiment
The present invention will be further described combined with specific embodiments below.
By taking the whole process of mail transmitting as an example：Mail generates, mail encryption, mail delivery, mail decryption, and mail is looked into
It reads.
Sender passes through the main contents of editor editor mail, including text, image and sound；It is answering
With layer, sender can be by being arranged password, mail opening time, and mail is opened the elements such as space address and made by oneself to mail
Justice encryption；In data Layer, system using password in plain text as the communications content that key edits sender by des encryption algorithm into
Row cryptographic calculation carries out cryptographic calculation to the password that sender is arranged by MD5 irreversible encryption algorithm in plain text；Addressee receives
After mail, it is necessary to which the time specified in sender and space input correct password, the original contents of mail just can be in by system
In face of present addressee, the present invention has carried out effectively encryption to mail data and has calculated either in application layer or data Layer
Method, so that entire data transmission be made to become safe and reliable.
