There are the circulation of data, data transmission between the entity object module and data inquiry module, service inquiry module Mode is divided into http and two kinds of transmission modes of https, and the data of transmission are encryption data, and the Encryption Algorithm used includes but not It is limited to: secure hash algorithm, MD5 algorithm.

Secure hash algorithm (English: Secure Hash Algorithm is abbreviated as SHA) is a Cryptographic Hash Function Family is the secure hash algorithm that FIPS is authenticated.It can calculate and arrive corresponding to a digital massage, the fixed character of length The algorithm of string (also known as eap-message digest).And if the message difference of input, the probability that they correspond to kinds of characters string are very high.

SHA algorithm process message data used in the present invention, includes the following steps:

Step 1: filling extra order

Filling message makes its length ≡ 896 (mod 1024).Filling is made of one 1 and subsequent 0.

Step 2: additional length

The block that 128 are added after message after filling, is regarded as signless integer, it includes the length of preceding message.

First two steps the result is that produce a length be 1024 integral multiples message, to be grouped.

Step 3: the initialization buffer area Hash

Hash function intermediate result and final result are stored in 512 buffer areas, and buffer area is by 8 64 registers (a, b, c, d, e, f, g, h) is indicated, and is following 64 integers (hexadecimal) by these initialization of register.

The mode that each content of registers obtains is: preceding 8 prime numbers (2,3,5,7,11,13,17,19) root of making even is taken, Take first 64 of fractional part.

Step 4: being unit processing message with 1024 groupings (128 bytes) and export result.

Message Digest Algorithm MD5 (the entitled Message Digest Algorithm 5 of Chinese) is computer security The widely used a kind of hash function in field, to provide the integrity protection of message.The document number of the algorithm is RFC 1321 (R.Rivest,MIT Laboratory for Computer Science and RSA Data Security Inc.April 1992).

The full name of MD5 is Message-Digest Algorithm 5 (md5-challenge), in the early 1990s by MIT The Ronald L.Rivest of Laboratory for Computer Science and RSA Data Security Inc is developed Come, is developed through MD2, MD3 and MD4.

MD5 is for ensuring that information transmission is complete consistent.Be one of widely used hash algorithm of computer (and translate abstract calculate Method, hash algorithm), mainstream programming language generally has MD5 and realizes.It is another fixed-length value by data (such as Chinese character) operation, It is the basic principle of hash algorithm, there are MD2, MD3 and MD4 in the predecessor of MD5.

The effect of MD5 is that large capacity information is allowed to be ' compressed ' into a kind of guarantor before signing private key with digital signature software Close format (being exactly the hexadecimal number word string for the byte serial of a random length being transformed into a fixed length).

The narration brief to MD5 algorithm can be with are as follows: MD5 handles the information of input with 512 groupings, and each grouping is again 16 32 seats groupings are divided into, after have passed through a series of processing, the output of algorithm is formed by four 32, by this 128 hashed values will be generated after four 32 packet concatenations.

In MD5 algorithm of the invention, it is necessary first to be filled to information, be equal to its bit length to the result of 512 complementations 448.Therefore, the bit length (Bits Length) of information will be scaled up to N*512+448, and N is a nonnegative integer, and N can be Zero.The method of filling is as follows, and one 1 and numerous 0 is filled behind information, just stops using when meeting condition above The filling of 0 pair of information.Then, message length before adding one behind this result with the filling of 64 binary representations.Through The processing of this two step is crossed, bit length=N*512+448+64=(N+1) * 512 of information, i.e. length are precisely 512 integral multiple.This The reason of sample is done is to meet the requirement in later process to message length.

The MD5 algorithm that the present invention uses has the following characteristics that

1, compressibility: the MD5 value length of the data of random length, calculating is fixed.

2, it is easy to calculate: calculating MD5 value from former data and be easy to.

3, anti-modification: making any change to former data, even only modifying 1 byte, obtained MD5 value has very Big difference.

4, strong impact resistant: known original data and its MD5 value are wanted to find data (the i.e. forgery number with identical MD5 value According to) it is very difficult.

The process of MD5 algorithm used in the present invention is as follows:

1. filling

In MD5 algorithm, it is necessary first to information is filled, makes its bit length to the result of 512 complementations equal to 448, and And filling must carry out, even if its bit length is equal to 448 to the result of 512 complementations.Therefore, the bit length (Bits Length) of information It will be scaled up to N*512+448, N is a nonnegative integer, and N can be zero.

The method of filling is as follows:

1) one 1 and numerous 0 is filled behind information, just stops 0 pair of information when meeting condition above Filling.

2) message length (unit Bit) before adding one behind this result with the filling of 64 binary representations, If message length is more than 64 before the filling of binary representation, low 64 are taken.

By the processing of this two step, bit length=N*512+448+64=(N+1) * 512 of information, i.e. length is precisely 512 Integral multiple.Reason for this is that meet the requirement in later process to message length.

2. initializing variable

128 initial place values are preliminary examination link variable, these parameters are used for the operation of the first round, carry out table with big end syllable sequence Show, they are respectively as follows: A=0x01234567, B=0x89ABCDEF, C=0xFEDCBA98, D=0x76543210.

(numerical value that each variable provides is that high byte is stored in memory low address, and low byte is stored in memory high address, i.e., greatly Hold syllable sequence.Variables A, the value of B, C, D are respectively 0x67452301,0xEFCDAB89,0x98BADCFE in a program, 0x10325476)。

3. handling packet data

The algorithm flow of each grouping is as follows:

First grouping needs to copy to four link variables above in four additional variable: A to a, B to b, C to c, D are arrived d.Variable since second packet is the operation result of a upper grouping, i.e. A=a, B=b, C=c, D=d.

Major cycle has four-wheel (MD4 only has three-wheel), and every wheel circulation is all much like.The first round carries out 16 operations.Behaviour every time Make to the wherein nonlinear function operation of three works in a, b, c and d, acquired results are then added into the 4th variable, text This subgroup and a constant.By acquired results, ring moves an indefinite number to the left again, and plus it in a, b, c or d One.Finally replace one of a, b, c or d with the result.

It is four nonlinear functions (every one, wheel) used in each operation below.

F (X, Y, Z)=(X&Y) | ((~X) &Z)

G (X, Y, Z)=(X&Z) | (Y& (~Z))

H (X, Y, Z)=X^Y^Z

I (X, Y, Z)=Y^ (X | (~Z))

(& be with (And), | be or (Or) ,~right and wrong (Not), ^ be exclusive or (Xor))

The explanation of this four functions: if the correspondence position of X, Y and Z be it is independent and uniform, result each It should be independent and uniform.

F is the function of a bitwise operation.That is, if X, Y, otherwise Z.Function H is odd even operator by turn.

Assuming that Mj indicates j-th of subgroup (from 0 to 15) of message, constant ti is 4294967296*abs (sin (i)) Integer part, for i value from 1 to 64, unit is radian.(4294967296=232)

Now define:

FF (a, b, c, d, Mj, s, ti) operation is a=b+ ((a+F (b, c, d)+Mj+ti) < < s)

GG (a, b, c, d, Mj, s, ti) operation is a=b+ ((a+G (b, c, d)+Mj+ti) < < s)

HH (a, b, c, d, Mj, s, ti) operation is a=b+ ((a+H (b, c, d)+Mj+ti) < < s)

II (a, b, c, d, Mj, s, ti) operation is a=b+ ((a+I (b, c, d)+Mj+ti) < < s)

Note: " < < " indicate ring shift left position, do not shift left.

This four-wheel (totally 64 step) is:
