It is encrypted, and the ciphertext after encryption and preset numbers are sent to data receiver, described preset numbers are used for mark data
Sender.
Wherein, SDK (Software Development Kit, SDK) Encryption Tool bag and this data are sent out
The numbering of the side of sending is preset in data sender, is packaged with respective encrypted algorithm, host-host protocol, encryption in SDK Encryption Tool bag
The information such as key, can be encrypted to target data to be encrypted automatically according to this SDK Encryption Tool bag.Preset numbers are permissible
Identify this data sender, preset numbers encode and be used for identifying the sequence number of user's name, data with least including user's registration
Recipient can determine unique data sender according to this preset numbers.
Specifically, when data sender generates data sending request, data sender calls SDK Encryption Tool bag automatically
Be encrypted to sent target data, thus target data is changed into ciphertext from plaintext, after the completion of encryption, by ciphertext and
Preset numbers are sent to data receiver together by HTTP interface.Wherein, HTTP interface can point to the IP of data receiver
Address.
S120, data receiver inquire about corresponding decruption key and SDK decryption package according to the preset numbers receiving.
Wherein, data receiver receives preset numbers and ciphertext by corresponding HTTP interface, and pre- according to receive
If numbering inquires about corresponding decruption key and SDK decryption package.
Wherein, be stored with data receiver preset numbers, the corresponding decruption key of this preset numbers and SDK deciphering work
Tool bag, is at least packaged with decipherment algorithm corresponding with AES in this SDK decryption package.It should be noted that with same
Preset numbers corresponding SDK Encryption Tool bag and SDK decryption package are mutually paired, and seal in this SDK Encryption Tool bag
In the AES of dress and this SDK decryption package, the decipherment algorithm of encapsulation matches, and in addition same preset numbers correspond to
Encryption key and decruption key be also match, such data receiver can according to receive preset numbers inquiry right
The decruption key answered and SDK decryption package, to be correctly decrypted.
