Using example：
Below completely encrypting, decrypting, backing up, is according to its course of work, its specific work is described in detail in recovery process It is as follows to make process：
As shown in figure 3, when user is being registered in terminal first, user cipher first can be sent by server, Because this operation also without triggering fission log in transactional operation condition because having not been entered into program at this time, can not also Carry out log in transactional operation.Operation is unregistered when the initial user by first time is finally exited into program.Note herein Pin operation for described in step 101 terminate programmed instruction or log in a triggering node behaviour after transactional operation Make.
Step a：When the terminal performs END instruction, then the user cipher, public key, private key, Yong Humi are generated First password, the second password that code includes are two string random characters, and public key, private key are then the public private key pairs of rsa.Its is public and private The algorithm of key passes through ECC (elliptic curve) using the public and private key of user.Afterwards,
Step b：The private key can carry out fission generation first private key, the second private key；
Step c：The terminal is encrypted the first password by the public key to obtain the first ciphertext, herein plus Close is to add salt encryption, and ciphering process hereafter is plus salt is encrypted, and password and salt are similarly generated after decryption, is no longer specially gone to live in the household of one's in-laws on getting married State, encrypted first ciphertext, sends to server together with first private key.
Step d：When terminal receive log in next time trading instruction when, the terminal sends out cell-phone number and the second private key Send to the server；Cell-phone number at this time is above-mentioned home identity.
Step e：After the server receives the first private key, the second private key and the first ciphertext, pass through the first private key and institute The second private key is stated to be reassembled as the private key and the first ciphertext is decrypted.First password is reduced to short message verification code Form passes terminal back.
Step f：The terminal and the second local password be combined be reduced to the user cipher perform log in hand over It is easy to operate.The server at this time takes out the private key of this operation.
For user in data on operational chain in the terminal, after identifying code and input validation is received, terminal is automatic Wallet password is replaced, and backs up and replace cryptoAPI to server calls wallet, transmits the line for logging in short message verification code next time Rope, on subsequent operation chain during data short message verification code acquisition, this is one-time pad.
Its backup procedure is as follows：
When private key fission is sent the terminal iidentification to the clothes by the terminal for the first private key and the second private key During business device, its backup procedure starts：
The terminal sends terminal iidentification to the server, and terminal iidentification at this time is user name, the server life Into server identification code for one with the associated key of path.Also create at the same time and upload voucher, the storage of public keys, storage Private key, and key, upload voucher, storage of public keys are sent to terminal；
Wallet file is encrypted with the storage of public keys in the terminal and is uploaded to high in the clouds.Described in the generation of high in the clouds High in the clouds identification code, the high in the clouds identification code are a key of oneself of high in the clouds generation, are carried out with the key of above-mentioned server generation Matching, successful match then update user's wallet path.
As shown in figure 4, the terminal receives the reduction instruction that user sends, reduction instruction be in program give for change wallet by Button, the terminal send user name to the server.The server, which receives to start after user name to download high in the clouds, to be added Wallet file after close, and the storage private key by locally generating is decrypted, finally, the server is by after decryption Wallet file is sent to the memory module.The memory module is default one rescue mailbox.
The wallet file after the terminal downloads decryption completes restoring operation after voluntarily importing.
Authentication process as described in Figure 9, the terminal send URI, http method, user name to the server, Ticket is obtained by server to send to terminal.The terminal signs Ticket by private key, together with business datum Send the Ticket to sign to the server, the server inspection and whether current interface matches, by inspection result industry Result of being engaged in or authentification failure return to the terminal.
