A part of embodiment of the present invention, rather than whole embodiments, based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained on the premise of creative work is not made, belongs to the scope of protection of the invention.
As shown in figure 1, one embodiment of the invention provides a kind of provision price control method, supervision center is applied to,
The method may comprise steps of：
Step 101：According to outside triggering, at least one provision price information is obtained；
Step 102：Provision price information each described is encrypted respectively by customized Message Digest 5, shape
Into the corresponding MD5 values of provision price information each described；

Enter.
A kind of provision price control method for being applied to supervision center is the embodiment of the invention provides, is obtained extremely according to triggering
After few provision price information, each provision price information is encrypted by customized Message Digest 5, is formed
A corresponding MD5 values, and the provision price information that will be got by non-on-line normalization mode and a corresponding MD5
Value is transferred to the grain purchases terminal of needs.Grain purchases terminal is by identical Message Digest 5 to each grain for receiving
Food pricing information is encrypted, and the 2nd MD5 values for being formed is contrasted with a corresponding Md5 values, it is determined that received
Provision price information be not tampered with after, provision price information importing is carried out according to the provision price information for receiving.So, lead to
Crossing MD5 values ensures the security of transmitted provision price information, such that it is able to by way of non-on-line normalization by provision price
Information transfer gives grain purchases terminal, so as to ensure can be normal during the network failure between supervision center and grain purchases terminal
Carry out grain purchases business.
In an embodiment of the invention, in a step 102 provision price information is encrypted to form corresponding
During one MD5 values, any one the current provision price information in each provision price information is directed to, is disappeared by customized
Breath digest algorithm is encrypted to the current provision price information and predefined encrypted characters string, and the MD5 values that will be formed
As a MD5 values of the current provision price information.Wherein, encrypted characters string is that supervision center is advance with grain purchases terminal
The inner cipher of agreement, and Message Digest 5 is the internal cryptographic algorithm that supervision center is used in conjunction with grain purchases terminal.
In a first aspect, Message Digest 5 is the internal cryptographic algorithm of supervision center and grain purchases terminal, and non-universal
MD5 algorithms, so, after lawless people is distorted to the provision price information for being sent to grain purchases terminal, due to nothing
Method obtains the Message Digest 5 of supervision center and grain purchases terminal inner, so as to cannot be obtained by the Message Digest 5
The MD5 value corresponding with rear provision price information is distorted.When grain purchases terminal by Message Digest 5 to the grain that receives
Food pricing information is encrypted, after forming corresponding MD5 values, if the MD5 values for being formed are different from the MD5 values for receiving, and can
Had been tampered with the provision price information received by determination.
For example, after supervision center is encrypted by Message Digest 5 A to the provision price information 1 of wheat 1, obtaining
MD5 values 1, grain purchases terminal is transferred to by offline mode by provision price information 1 and MD5 values 1.In transmitting procedure China Oil and Food Import and Export Corporation
Food pricing information 1 is intercepted and captured with MD5 values 1 by lawless people X, and lawless people X distort forming grain valency to provision price information 1
Lattice information 2, due to that cannot obtain Message Digest 5 A, is directly transmitted to grain purchases end by provision price information 2 and MD5 values 1
End.Grain purchases terminal is being received after provision price information 2 and MD5 values 1, by Message Digest 5 A to provision price
Information 2 is encrypted, and forms MD5 values 2.Because provision price information 2 is different from provision price information 1, by same message
Digest algorithm A is encrypted formed MD5 values 2 to provision price information 2 and will be encrypted shape with to provision price information 1
Into MD5 values 1 it is different, when MD5 values 2 are different from MD5 values 1, it may be determined that received provision price information 2 is usurped
Change.
Provision price information is encrypted by inside story digest algorithm, because lawless people cannot be obtained inside this
Message Digest 5, thus cannot to distorting after the corresponding MD5 values of provision price information effectively updated, such that it is able to root
Judge whether provision price information is tampered according to the MD5 values transmitted together with provision price information, prevent the grain after distorting
Pricing information is imported into, and improves the security of the provision price control method.
Second aspect, is encrypted by Message Digest 5 to provision price information and predefined encrypted characters string,
A MD5 value of the MD5 values that will be formed as provision price information.Because encrypted characters string is supervision center and grain purchases
The inner cipher that terminal is appointed, supervision center and grain purchases terminal are carried out by Message Digest 5 to provision price information
During encryption, encrypted characters string is together encrypted.So, even if lawless people obtains the message of provision price information and inside
Digest algorithm, but the provision price information match after it still cannot be formed and distorted on the premise of there is no encrypted characters string
MD5 values, so as to still be able to according to MD5 values determine provision price information whether be tampered, prevent the provision price that will be tampered
Information is imported, and further increases the security of the provision price control method.
For example, kind information of the provision price information 1 of wheat 1 including wheat 1, the class information of wheat 1, wheat 1
The multinomial informations such as stock's property information, pricing information renewal time, are wrapped by Message Digest 5 A to provision price information 1
The every terms of information and predefined 6 bit encryption character string C for including are encrypted, and form MD5 values 1.By offline mode by grain
Pricing information 1 is transferred to grain purchases terminal with MD5 values 1.Provision price information 1 and MD5 values 1 are by not legal person in transmitting procedure
Member X is intercepted and captured, and lawless people X to provision price information 1 distort forming provision price information 2, and lawless people X is plucked by message
Provision price information 1 after algorithm A is wanted to distorting is encrypted to form MD5 values 2, and by 2 turns of provision price information 2 and MD5 values
Issue grain purchases terminal.Every terms of information that grain purchases terminal is included by Message Digest 5 A to provision price information 2 and
6 bit encryption character string C are encrypted, and form MD5 values 3.Due to lawless people X-shaped into during MD5 values 2 not use encrypted characters string
Or the encrypted characters string for being used is different from 6 bit encryption character string C, causes MD5 to 2 different from MD5 values 3, may thereby determine that
Received provision price information 2 has been tampered with.
In an embodiment of the invention, provision price information is encrypted to form a corresponding MD5 in step 102
During value, if the number of the provision price information got in step 101 is more than 1, carried out to a provision price information
During encryption, according to pre-defined circulation encryption rule, determine and the provision price information phase from each provision price information
At least one association provision price information of association, and then by Message Digest 5 to provision price information, the encrypted characters
String and at least one association provision price information being associated with the provision price information are encrypted, and the MD5 values that will be formed are made
It is a MD5 values of the provision price information.
For example, the need for according to grain purchases terminal, obtaining wheat, soybean, corn, paddy rice totally 4 kinds of grain valencys of grain
Lattice information, wherein wheat correspondence provision price information 1, soybean correspondence provision price information 2, corn correspondence provision price information 3,
Paddy rice correspondence provision price information 4.According to pre-defined circulation encryption rule, determine that provision price information 2 is provision price
The association provision price information of information 1, provision price information 3 is the association provision price information of provision price information 2, grain valency
Lattice information 4 is the association provision price information of provision price information 3, and provision price information 1 is the association grain of provision price information 4
Food pricing information.When being encrypted to provision price information 1, by Message Digest 5 A to provision price information 1 and grain
The every terms of information and encrypted characters string that pricing information 2 includes are encrypted, and the MD5 values that will be formed are used as provision price information 1
First MD5 values；When being encrypted to provision price information 2, by Message Digest 5 A to provision price information 2 and grain
The every terms of information and encrypted characters string that pricing information 3 includes are encrypted, and the MD5 values that will be formed are used as provision price information 2
First MD5 values；Correspondingly, provision price information 3 and provision price information 4 are encrypted respectively using identical method, are obtained
Obtain a MD5 values accordingly.
By circulating encryption rule, when being encrypted to a provision price information, with reference to other provision price information
Content, after some provision price information are deleted by lawless people, can cause remaining provision price information MD5 values verify not
Pass through such that it is able to ensure that provision price control sends the integrality for transmitting provision price information.
As shown in Fig. 2 one embodiment of the invention provides a kind of provision price control method, grain purchases end is applied to
End, the method may comprise steps of：
Step 201：With at least one provision price information that non-on-line normalization mode, the supervision center outside reception send
And a corresponding MD5 values, wherein, a MD5 values pass through customized Message Digest 5 pair by the supervision center
Corresponding provision price information is encrypted and obtains；
Step 202：Each described provision price information by the Message Digest 5 respectively to receiving is added
It is close, form the corresponding 2nd MD5 values of each described provision price information；
Step 203：Each described provision price information is directed to, the provision price information corresponding described is judged
Whether one MD5 values are identical with the 2nd MD5 values, if it is, carrying out provision price importing according to the provision price information.
One embodiment of the invention provides a kind of provision price control method for being applied to grain purchases terminal, by non-
On-line normalization mode, after receiving provision price information and a corresponding MD5 values, is directed to each provision price information,
Provision price information is encrypted by predefined Message Digest 5, obtains the 2nd corresponding MD5 values, if first
MD5 values are identical with the 2nd MD5 values, then can determine that the provision price information is not tampered with, and then believed according to the provision price
Breath carries out provision price importing.As can be seen here, the security of received provision price information is ensured by MD5 values, such that it is able to
