Wherein, Fig. 3 shows the data encryption in a kind of communication system being applied in Fig. 1 provided in an embodiment of the present invention
The flow chart of method, is specifically included：Step S301-S304.
Step S301：The identification information of the receiving terminal is obtained, and the public key prestored.
Terminal is sent when sending data, it is necessary to obtain the identification information of intended recipient terminal, could be by number to be sent
According to corresponding receiving terminal is sent to, if data to be sent need to encrypt when sending, in addition it is also necessary to obtain the public key prestored
Data can be encrypted.Wherein it is preferred to, the public key prestored is stored in server end, so as to multiple terminals
Share.
Step S302：According to the operating system of the transmission terminal, obtained and sent with described by default encryption interface
The corresponding AES of the operating system of terminal.
In order to avoid in existing encryption technology, each platform uses different encryption calling interfaces, such different platform it is upper
Layer is applied when calling underlying algorithm, it is necessary to different program codes, not only increases its workload, also add use, dimension
The costs such as shield so that the leap between platform is poor.In the present embodiment, the unification of different platform is realized by default encryption interface
Call, for example, Android system is when calling underlying algorithm, calls encryption interface A, IOS system when calling underlying algorithm, also adjust
With encryption interface A, so allow for a set of code can many places use, reduce workload, saved use, maintenance cost,
So that the leap between platform is good.Wherein, the calling interface that predetermined encryption interface is according to actual needs and is pre-designed,
The AES corresponding with the operating system of the transmission terminal can be obtained by the encryption interface.Wherein, it is whole when sending
When the operating system at end is PC or Android operation system, the AES got by default encryption interface is
The AES encapsulated using Java language.When the operating system for sending terminal is IOS, pass through default encryption
The AES that interface is got is the AES encapsulated using OpenSSL.
Step S303：Be-encrypted data is carried out according to the public key, the identification information and acquired AES
Encryption.
Get after public key, the identification information of receiving terminal and corresponding AES, according to the public key, the mark
Know information and be-encrypted data is encrypted acquired AES, the data after being encrypted.Wherein, can during encryption
To use symmetric encipherment algorithm or rivest, shamir, adelman.
Step S304：Data after encryption are sent to the receiving terminal.
After data after being encrypted, receiving terminal is sent it to.Wherein, including, the data after encryption are saved in
Server database, is sent the data after encryption to the receiving terminal by the server.During transmission, according to getting
Identification information, server is sent the data after encryption to the receiving terminal corresponding with the identification information.
The embodiments of the invention provide the data decryption method in a kind of communication system 100 being applied in Fig. 1, such as Fig. 4
It is shown.Wherein, Fig. 4 shows a kind of flow chart of data decryption method provided in an embodiment of the present invention, specifically includes：Step
S401-S404.
Step S401：Receive and identify the encryption information sent by the transmission terminal.
Receiving terminal is got by transmission terminal after the data message that server is sent, to received data message
Judged, judge whether received data message is encryption information, if received data message is encryption information
When, then perform step S402.
Wherein, mode is preferably carried out as one kind, whether can possesses encryption according to received data message
Header is come whether judge received data message be encryption information.
Step S402：When it is encryption information to identify received information, obtain the key that prestores, the key with
Public key in above-mentioned data ciphering method is corresponding.
When it is encryption information to identify received information, the key prestored is obtained, in order to the encryption information
Operation is decrypted.Wherein, the key is corresponding with the public key in above-mentioned data ciphering method.Even the encryption information is to adopt
It is encrypted what is obtained with symmetric encipherment algorithm, then the key is identical with public key, for example, public key is 123456, then key is also
123456.Obtained if the encryption information is encrypted using rivest, shamir, adelman, the key is corresponding with public key
Private key, for example, public key is 123456, then the key is corresponding private key, for example, being 654321.Wherein public key and private
Key can be defined according to user using rule oneself.It should be appreciated that cited public key and private key in above-mentioned are only
It is for only for ease of and understands and illustrated example, can not be understood as being limitation of the present invention.
Step S403：According to the operating system of the receiving terminal, obtained and received with described by default encryption interface
The corresponding decipherment algorithm of the operating system of terminal.
In order to avoid in existing decryption technology, each platform uses different decryption calling interfaces, such different platform it is upper
Layer is applied when calling underlying algorithm, it is necessary to different program codes, not only increases its workload, also add use, dimension
The costs such as shield so that the leap between platform is poor.In the present embodiment, the unification of different platform is realized by default decryption interface
Call, for example, Android system is when calling underlying algorithm, calls decryption interface A, IOS system when calling underlying algorithm, also adjust
Use decryption interface A, so allow for a set of code can many places use, reduce workload, saved use, maintenance cost,
So that the leap between platform is good.Wherein, the calling interface that default decryption interface is according to actual needs and is pre-designed,
The decipherment algorithm corresponding with the operating system of the receiving terminal can be obtained by the decryption interface.Wherein, it is whole when receiving
When the operating system at end is PC or Android operation system, the decipherment algorithm got by default decryption interface is
The decipherment algorithm encapsulated using Java language.When the operating system of receiving terminal is IOS, pass through default decryption
The decipherment algorithm that interface is got is the decipherment algorithm encapsulated using OpenSSL.
Step S404：The encryption information is decrypted according to the key and acquired decipherment algorithm, solved
Confidential information.
Get after key and corresponding decipherment algorithm, added according to the key and acquired decipherment algorithm to described
Confidential information is decrypted, and obtains solving confidential information.Wherein, during decryption, symmetrical decipherment algorithm or asymmetric decipherment algorithm can be used.
