Specific embodiment

Digitlization soil identity card management includes ATTRIBUTE INDEX setting, data acquisition, generates digitlization identity card, certificate pipe Manage four steps.

One, ATTRIBUTE INDEX is arranged

1, farming land ATTRIBUTE INDEX introduction

ATTRIBUTE INDEX is one of most important part in soil identity card, selects these attribute value required representative With universal practicability, experiment and tracking feedback at long-term scene have carried out multiple optimization processing, the index value of selection It is as follows:

2, farming land ATTRIBUTE INDEX value

The value range of each ATTRIBUTE INDEX of farmland is bound, is measured according to historical empirical data statistics and scientific research, Recommend reasonable value range.

Farming land plot digital ID card (ATTRIBUTE INDEX)

Two, data acquire

The mode of data acquisition mainly has mobile phone terminal software collection mode, exchanges data etc. with existing system development interface. Mobile phone terminal software is by the typing of mobile phone terminal software block message at the scene, and then submission system saves.The mode of development interface Local Land Resources Management system is needed to be docked, some data can send in this way, not need to acquire again.

Three, digitlization soil identity card generates

Digital Land identity card coding is the unique encodings in the plot, while identity card coding embodies the category in the plot completely Property value.Nearly 50 attribute values in the plot are just understood completely by coding, this is also the value dimension for digitizing soil identity card.Together When also to guarantee the information security of farmland.The rule of coding partners the attribute in soil and the mode of value, then institute Do RSA asymmetric encryption to value one Jason message of composition, then to the message by what these attributes and value formed, generation it is close Text is exactly the digitlization identity card coding in the plot.Example below such as:

1, the message generated according to ATTRIBUTE INDEX

2, message is encrypted, generates digitlization identity card

The attribute message in a plot is just defined above, and asymmetric encryption then is carried out to this attribute message, it is just raw At the digitlization soil identity card in the plot.RSA (landfile), for example following appearance of the ciphertext of generation (example):

nqFy7ovnt6UHpfzw1NQfimKQw7RUhCnceXL7quXtUDomFcJncw5qyVcB12GF4FICbz9je +nuPeWfNh0GW2F849DjqgpgtcgovH+ZdU0mFUwuZA/R6zbkLdzmC4GKQp/Gr3hyPLPKDjt+ie+ RVAqQ9GVcniYqmuNmm0px2vwqdY4=

Ciphertext above is exactly the digitlization identity coding in the plot.In the application of subsequent system, such as land transformation is supported The operations such as signature, supervision, it is desirable to provide identity card coding, so that it may which the details for obtaining the plot simplify transaction flow. The information in plot is obtained by digitlization identity card, it is only necessary to operation is decrypted in identity card coding, so that it may obtain plot The value of each field is the inverse operation of encryption.

Four, certificate management

RSA cryptographic algorithms are current most influential public key encryption algorithms, and are generally considered fitst water at present One of public key scheme.

Public-key cryptography (public key) and private cipher key (private key).Public-key cryptography and private cipher key are a pair, If encrypted with public-key cryptography to data, could only be decrypted with corresponding private cipher key；If with private cipher key logarithm According to being encrypted, then could only be decrypted with corresponding public-key cryptography.Because encryption and decryption use two it is different Key, so this algorithm is called rivest, shamir, adelman.

Fig. 3 illustrates the generation of digitlization identity card and resolving.

Original document (clear text file) is encrypted with the public key certificate of recipient, is transmitted after generating ciphertext, and recipient receives To be cryptogam, then with the private key certificate of oneself, be decrypted, just obtain original document (plaintext).

There are a set of certificate, including public key certificate and private key certificate in each peasant household.Certificate is required in system and peasant household end It keeps.
