Description
Technical field
The present invention relates to the generation of enciphered digital currency private key and the device field of store method and carrying enciphered digital currency private key.
Background technology
Existing enciphered digital currency is as current main flow enciphered digital currency-bit coin, and be a kind of integration P2P (the point-to-point procotol in internet), internet, the digital cash of a kind of decentralization attribute of principle is learned in encryption.
In enciphered digital currency, the money of form of ownership is all the formal description of the rule that agreement (All forms of money are protocol) namely all money all must be observed before concluding the business.As the agreement that bit coin is exactly a kind of higher form, it utilizes Internet technology and cryptography and newly designed software, and cryptographic application ensure that the security of payment system.So, the difference that bit coin is too not large with other currency in this respect.What bit coin was unique is a bit its general ledger system (ledger system) is decentralization, and other currency has a central office to issue currency.
First digital cash user installs the wallet software of this digital cash at computer, this Software Create wallet (as than treating that coin is kept in computer with wallet.dat form).Wallet generates multiple bit coin address, and address is that the account of external disclosure is used for receiving others and issues your bit coin.
The private key that wallet generation enciphered digital currency address just has this address corresponding and PKI, current private key and PKI are included in wallet archives (wallet.dat).
Disclosed in the transaction of all enciphered digital currency is all, as All Activity in bit coin confirms just to be integrated into once the whole network " total account book is disclosed " (shared public ledger) be again block chain (Blockchain), the not independent record of surplus (Balance) of each wallet, the Transaction Information being all through block chain calculates into the surplus that owner takes in payment.Block chain is through encryption and forms according to transaction record and time sequencing integration." transaction of bit coin " is exactly that value between each bit coin wallet turns money record and is incorporated into block chain.
In enciphered digital currency, private key (private key) is a string information be kept in wallet.As in bit coin, private key is just kept in wallet archives wallet.dat.The effect of private key is used to produce PKI (this PKI can derive bit coin address), and is used for the digital signature of transacting business.This signature ensure that the reliability of transaction, is not tampered, undeniable integrality.All transaction records all can be broadcast to customer group, and are confirmed by the whole network in the next stipulated time (if bit coin is exactly next 10 minutes), and this process is also called digs ore deposit (Mining).
Figure 1 shows that current bit coin process of exchange:
For the transaction 1 in such as Fig. 1, if B thinks that payment 100 bit coin (100BTC) are to C, so B not only needs to indicate the amount of money on trading card, and needs the source of these 100 bit coin dated.As shown in Figure 1, the 100BTC of B, in fact from A, is that B passes through transaction 0 and obtains, and 0 certification that have passed the whole network user of concluding the business here, is kept in the computer of all users.
The information of filling on trading card is needed to comprise for completing transaction 1, B:
The source of 100BTC is the ID of trading card 0 herein;
The PKI of C is also the bit coin gathering address of C;
Be the PKI input hash function by the content of trading card 0 and C, obtain string number.B this string numeral of encrypted private key of oneself, is placed in trading card 1 as digital signature.C, after receiving trading card 1, can find trading card 0 by the ID wherein deposited, and obtain the PKI of B.C can use this PKI to be decrypted the digital signature in trading card 1.Meanwhile, C the content of the PKI of oneself and trading card 0, can input hash function, and the result that the numeral obtained and digital signature are deciphered is compared in the same way.
If comparison success, following two facts just can be determined:
One, the source of 100BTC is true.Because contain the signature of A in trading card 0, and trading card 0 is through that all-web authentication crosses, and namely 100BTC is given B by A really;
Its two, transaction 1 really via B signature.Private key due to B is unique, and it is easy that he cannot deny this single cross.
The structure of existing enciphered digital currency has following shortcoming:
First be the hidden danger of secure context:
As the main representative of enciphered digital currency, although the checking experienced more than 5 years of the agreement of bit coin and encryption technology confirms that the security of bit coin is very high.But the private key of user (private key) is kept at the inner a string information of bit coin wallet (generally existing in computer hard disc with the archives form of wallet.dat), and your private key is exactly your bit coin! Because private key exists in wallet, and wallet is the archives of the wallet.dat that there is computer.As long as archives are just likely read or lose! Other enciphered digital currency nearly all is all adopt this mechanism.This mechanism can because the not rigorous of user's ubiquitous inertia behavior brings greatly risk and inconvenience.
Private key is generated by wallet software, and the producing method of private key is easily controlled and illegally utilized.
Private key is stored in wallet file, and the preserving type of private key easily causes losing, damaging or be stolen.
Use private key to be completed by wallet software the process of signing of concluding the business, the signature scheme of private key easily causes private key tackled by unused code and reveal.
In addition, the structure of above-mentioned enciphered digital currency causes complex operation, uses inconvenience, causes user group single, can not attract more user.
Wallet is generated by the client software of computer, is used by computer position limitation.Use the use habit of bank card different from general tradition, user needs study and is bundled in equipment (computer or mobile phone).Cause to fear and use, cannot generally apply in daily life.
Even if bit coin industry has some improvement projects, except software wallet also has some as network wallet (Web Wallet), paper money bag (Paper wallet), brain wallet (Brain wallet), all do not flee from private key exists oneself computer with the form of archives, or the possibility of in third party's network wallet server, just likely losing (computer damages or website is closed) and being stolen.
