Background technique
Centralization login mode user name, password, mobile phone identifying code.The advantages of centralization login mode, is: account number cipher
Be stored in the server of centralization, user forget Password Shi Kexiang central server application resetting password, not because forgetting Password
And lose assets.The shortcomings that centralization login mode, is: the login mode of centralization, such as traditional financial institution such as bank,
For the assets of user by central server trustship, assets are the numerical chracter of a presentation, this number in the account of user
It is also often influenced by the operation troubles of center system and many uncontrollable additional risks must not be not subject to.When background user is believed
Breath Management System Data is distorted by people, and user carries out that corresponding data will can not be obtained when authentication, is not available the account
Password carries out register.And after user account password information is tampered, the criminal for distorting information will be easy to obtain
The information in user account is taken, the trade secret or individual privacy of company have been revealed.
Block chain login mode uses private key+public key, KEYSTORE+PASSWORD, mnemonic word.Private key is substantially one
The fixed random number of length.Public key is generated by private key by elliptic curve, is the array of 65 byte after transformation, usually
It is shown after being handled by 16 systems.When we possess a private key, so that it may calculate public key.And public key cannot calculate private key.
KEYSTORE is not private key, is common in ether mill wallet, after general creation ether mill wallet, you can be allowed to back up KEYSTORE, it
It is a string of codes, oneself can saves as text or json format, it can be opened with any ether mill wallet in the future.
The essence of KEYSTORE is encrypted private key, KEYSTORE must cooperate your wallet password come using.What PASSWORD referred to
It is to need to set a password when creating wallet, there are two main applications, first is that payment cipher when transferring accounts, second is that with
KEYSTORE imports login password when wallet.Mnemonic word is another form of expression of private key, is proposed by 31 motion of BIP, main
Syllabus is the private key for allowing user preferably to remember oneself, after creating wallet, it may appear that a backup mnemonic word function selects standby
Part mnemonic word inputs password, it may appear that 12 words have a space between each word, this is exactly mnemonic word,
It wraps only one mnemonic word and cannot modify.
The advantages of block chain login mode, is: decentralization, convenient and efficient, high security, book keeping operation speed is fast, cost compared with
Low, mutual supervision verifying.Point-to-point login mode is made by block chain technology, excludes the intermediate ring of third party financial institution
Section cancels invisible cost.The shortcomings that block chain login mode, is: currently, there are many block chain Wallet System, these wallet systems
In system, login mode file includes terminal storage, server two kinds of storage modes of storage.When terminal storage, login mode file
It is easy to be copied, replicate, login mode exists by risks such as Brute Forces.When server stores, login mode is generally all by handing over
Easy core agent management, must input trading password every time when transaction, the existing login mode file of trade center also has transaction close
Code, causes risk factor very big, once trade center, which occurs, the risks such as attack, is closed, the possibility of assets loss in wallet
Property is very big.
