The record of block chain is full disclosure, everybody can obtain the copy of all records, and people is encouraged to participate in jointly；With bit coin
Block chain for, each person of participating in business is the node of block network, and each node has a complete public account
Book backs up, and has recite all Transaction Informations since bit coin is born above.Any one node, which initiates trading activity, all to be needed
Each node relevant information being transmitted in block network, so as to which the account book on all nodes can verify that this is handed over
It is easy to be and accurately update.In addition, account book is blockette storage, with the increase of transaction, new data block can be attached to
Through on existing chain, forming chain structure.Simultaneously as block chain is by the restriction that exercises supervision in many ways, therefore, block chain tool
There is the characteristic that can not be distorted, that is, upload to the data of block chain, cannot change, ensure that the authenticity of data.If
There is malicious node to provide false data, then false data will permanently be recorded as the history criminal evidence, so as to greatly reduce false number
According to upload.Therefore, using preserving the contract of signing into block chain in the embodiment of the present invention, so as to ensure that the true of contract
Reality, and contract is prevented to be tampered, after preservation, when needing that contract is encrypted, it is necessary first to which extraction needs to add
Then close contract is ensureing not injuring the base for carrying out the number signing platform security for signing contract and ensureing contract party's privacy
On plinth, the contract extracted is encrypted, wherein, in order to ensure safety of the contract in data transmission procedure, can combine
The encryption thought of symmetric cryptography and asymmetric encryption, has carried out contract multi-layer security, wherein symmetric cryptography refer to send and
For the both sides of reception data using identical key (symmetric key) to being encrypted and decrypted in plain text, encryption/decryption speed is fast, fits
Conjunction handles mass data, but just since encryption and decryption is using same symmetric key, for symmetric key management compared with
For difficulty.And asymmetric encryption then needs two keys：Public-key cryptography (public key) and private cipher key (private key), public key is to other sides
Open, private key then oneself preserves；Public key is a pair of with private key, if data are encrypted with public key, only with corresponding private
Key could be decrypted；If data are encrypted with private key, then could only be decrypted with corresponding public key；Added due to asymmetric
Close algorithm is complicated so that the speed that encrypting and decrypting speed does not have symmetric cryptography to decrypt is fast, but due to encryption and decryption key not
