Description
Technical field
The present invention relates to a kind of safe Wallet System of block chain, terminal (PC, APP) block chain wallet is based in use, logical
Cross the dynamic encryption and decryption technology of operating system kernel level, HOOK technology, safety shield control technology realize to block chain wallet password,
Code key file carries out protection backup, to avoid the leakage of block chain key information, causes irremediable loss.
Abbreviation and explanation of nouns:
API: application programming interfaces
PC: computer (personal computer)
APP: application program of mobile phone
HOOK: Hook Technique
Background technique
As block chain technical application is more and more extensive, trade more and more.Block chain code key is without uninscribed, the code key of certification
File loss can not be given for change, code key file is stolen, and password, which is cracked, leads to imponderable loss.Presently, there are various
Wallet System, there are two types of storage modes for code key file: terminal storage, server store two ways.When terminal storage, code key text
Part is easy to be copied, replicate.Key is by risks such as Brute Forces.When server stores, code key is typically all by trade center generation
Reason management, must trade when transaction input trading password every time, the existing code key file of trade center also has trading password, risk system
Number is very big.Once a possibility that trade center such as is attacked, closed at the risks, and wallet is lost is very big.
There is a kind cold wallet processing scheme at present, on the physically-isolated network wallet storage, is needed when transaction every time
Online terminal is used to interact with the multiple signature authentication of cold wallet, such method can solve wallet and be asked by network attack
Topic.But process of exchange is complicated, and not can solve wallet and the risks such as replicate, crack by artificial copy.
Summary of the invention
It is in terminal (PC terminal, APP) in application, logical the present invention provides a kind of safe Wallet System of block chain and method
The dynamic encryption and decryption technology of operating system kernel level is crossed, it can be achieved that a kind of safe wallet application of block chain, solves block chain wallet
Safety issue.
A kind of safe Wallet System of block chain of the present invention ensures wallet safety from three levels.
1. only insertion safety shield just can star wallet program, safety shield carries out authentication secret, certification when accessing wallet
By just can star wallet.
2. a pair code key file encrypts, when legal wallet process access, dynamic encryption and decryption program is decrypted in memory,
Allow to access key information.Refuse the access of other illegal programs, guarantees code key file data safety and access safety.
3. pair encryption a code key file carry out cloud backup, when code key file lose when from cloud platform restore, safety shield lose
When, through safety certification after the safety shield new from new production.
Fig. 1 is a kind of safe Wallet System of block chain of the present invention, including
