Volume register, in order to improve the safety that different service terminals implement the registration register, it is necessary to provide and provide one kind
With the registration code compared with high safety factor.To achieve the goals above, the registration code generation module of the authorization terminal generates the note
The detailed process of volume code can be as follows.
The registration code generation module, which is generated in registration code, to be realized based on the data from the service terminal, wherein
Source data from the service terminal may include but be not limited to be the corresponding manager's title of the service terminal, the service terminal pair
Start Date of the IP address or domain name, the service terminal service implementation answered, the service terminal service implementation date of expiry,
Activation date of the service terminal, resource access list (i.e. the addressable curriculum information list of the client terminal) etc., in the note
Actually generating in algorithm for code of volume can according to actual needs be extended the source data of the algorithm, which is not limited to
The above-mentioned data type enumerated.Correspondingly, the source data set s from the service terminal is represented by s={ s1,s2,…,sn},
Above-mentioned expression formula indicates that source data set s includes the different types of source data of n kind, and the length of every kind of source data is not
It immobilizes, the length of source data can be set according to the actual situation, such as the Start Date of the service terminal service implementation
It is typically mutually different with the corresponding source data length of resource access list.
Specifically, the process that the registration code generation module generates the registration code includes:
Firstly, to source data set s={ s1,s2,…,snEach of source data element siImplement to extract 32
The operation of bit cryptographic Hash；Correspondingly, it is assumed that source data element siIt carries out Hash operation and obtains its corresponding first Hash
Value h1i, while obtaining source data element siData length k (i.e. source data element siInclude k byte), at this point, si
[j] indicates source data element siJ-th of byte data；
Correspondingly, by following first conversion process by first cryptographic Hash h1iIt is converted into one second cryptographic Hash h2i, this
One conversion process is as follows:
Initialize first cryptographic Hash h1iWith byte data si[j], even if h1i=1 and j=0, then passes sequentially through down
First cryptographic Hash h1 of face formula (A1)-(A4) to the initializationiK loop computation is carried out,
hi=hi+si[j] (A1)
hi=hi+(hi< < 7) (A2)
hi=hi^(hi> > 5) (A3)
J=j+1 (A4)
Wherein, symbol ^ indicates power operation, and symbol " expression is moved to the left specific bit position data, symbol " expression moves right
Dynamic specific bit position data, such as formula hi=hi^(hi> > 5) it indicates first by hiMove right 5 bits and to obtain one new
Data h 'i, at this time
After the completion of the first conversion process, in the second cryptographic Hash h2 obtained to the first conversion processiImplement one
Two calculating process simultaneously obtain corresponding third cryptographic Hash h3i, which is specially to second cryptographic Hash h2iSuccessively
Execute the operation of following formula (A5)-(A7)
hi=hi+(hi< < 7) (A5)
hi=hi^(hi> > 5) (A6)
hi=hi+(hi< < 7) (A7)
The third cryptographic Hash h3 obtained by first calculating process and the second calculating processiAs a certain source data member
Plain siThe cryptographic Hash of corresponding 32 bits.Due to applied in first calculating process and the second calculating process 5 and 7 this two
A prime number, therefore first calculating process and the second calculating process is combinable becomes five or seven hash algorithms, which is
The teaching and the dedicated algorithm of demo system.When implementing the verification operation about the registration code, it is based on source data set s=
{s1,s2,…,snAnd by five or seven hash algorithm, the cryptographic Hash h of n 32 bits can be correspondingly made availablei, and form one and breathe out
Uncommon value set h={ h1,h2,…,hn}.Since the type and data length of the source data of different service terminals offer be not identical,
It would also vary from by the cryptographic Hash number that five or seven hash algorithm obtains, for the ease of subsequent operation, can set here at this time
Set the character string that the registration code ultimately generated is 16 bytes.
The registration code is obtained in order to calculate, which also calculates the registration using universal information digest algorithm function MD5
Code R, wherein R=MD5 (h), wherein h={ h1,h2,…,hn}.Through the above way it is found that the teaching and demo system pass through one
Five or seven Hash are calculated and universal information digest algorithm function MD5 combines to calculate the final data for obtaining the registration code.Then, exist
During carrying out verification operation to the registration code, as long as re-executing one new note of primary acquisition according to above-mentioned the step of introducing
Volume code R ', then the new registration code R ' and the authorization terminal registration code R provided are compared and just can determine current note
Whether volume code is effective, and even R ' ≠ R, then current registration code is invalid, if R '=R, current registration code is effective, or should
Note of the new registration code R ' preservation into a registration code library, in the registration code R and the registration code library that the authorization terminal is provided
Volume code compares can determine whether current registration code is effective.As long as it can be seen that when the corresponding manager's name of the service terminal
Title, the corresponding IP address of the service terminal or domain name, the Start Date of the service terminal service implementation, the service terminal are implemented
Any one source data in the date of expiry of service, the activation date of the service terminal, resource access list etc. is modified, then
Corresponding registration code is exactly invalid.
In addition, the service terminal to the authorization terminal carry out teaching resource access operation can be used an access matrix A into
Row indicates that the expression formula of access matrix A can be
Wherein, m indicates the quantity of the service terminal, and n indicates the quantity of the teaching resource.The access matrix can be used for defining
About the access list of the access operation, and the corresponding access authority of limitation, provided for example, only imparting knowledge to students when the 3rd server-side
The access authority in source 5 and 9, then coordinate (3,5) in access matrix A and (3,9) corresponding element can be set as to 1, and other
The corresponding element of teaching resource for not having access authority is set as 0, i.e. A [3 ,-(5,9)]=0, here-(5,9) indicate in addition to
Number is the number of other teaching resources outside 3 and 9, and A [3 ,-(5,9)]=0 indicates that the service terminal of number 3 removes and is able to access that

Then indicate that corresponding client terminal is able to access that corresponding teaching resource, if the value of a certain matrix element of access matrix C is
0, then it represents that corresponding client terminal cannot access corresponding teaching resource, it is seen that access matrix C can be with simple and clear
Access situation of the mode to each client terminal about teaching resource is defined.For t-th of client terminal, visited if it has
It asks the permission of i-th of service terminal, then depends on the access square the case where teaching resource that t-th of client terminal is able to access that
Battle array the i-th row of A and the t row of access matrix C correspondingly indicate that the i-th row of matrix A is lifted in access with A [i], C [t] is indicated
