Collect property and simplicity.
A kind of dynamic encrypting method based on digital signal data provided by the invention, locates data to be transmitted in advance
Reason；Treated data to be transmitted is packaged according to preset data form and generates encryption data；Encryption data is transmitted.It should
Method is for passing through the random number to transmission data progress specified range using data as the data dynamic encrypting method of unit of transfer
Operation generates dynamic pointer and encryption algorithm code number；Data encryption basis code character is generated in pointer designated position, with this number
On the basis of group, operation is carried out by the specified Encryption Algorithm of encrypted code number, generates encryption data.After data are received, according to
The specified digital group of algorithmic code number in data specified algorithm and pointer carries out data operation, restoring data.This method
It is effectively applied to the data transmission based on data of high confidentiality requirement, prevents data from divulging a secret in the transmission, has
There are accuracy, flexibility and the ease for use of application.
In order to it is more clear with accurately understand and apply this disclosure relates to a kind of dynamic based on digital signal data
Encryption method carries out following example in conjunction with Fig. 2-4, it should be noted that the range that the disclosure is protected is not limited to following example.
Specifically, the technical problem to be solved is that how to add in the dynamic for carrying out being more difficult to crack to valid data for the disclosure
It is close.For this purpose, the present disclosure proposes a kind of dynamic encrypting methods of digital signal data.Specific steps include: communication be with
The digital signal that data mode is sent, no matter signal is with wired or wireless mode (comprising public communication network, such as 4G, NB-
IoT etc.) transmission；Increase three parts in data format: pointer: the position to provide data cryptography infrastructure code character, using random
Number operation generates；Encryption algorithm code number: it to specify this to communicate the Encryption Algorithm code name used, is produced using random number operation
It is raw；Data encryption basis code character: valid data carry out the additional related data of cryptographic calculation, are generated using random number operation.
It should be noted that pointer, encryption algorithm code number, data encryption basis code character a few with encrypt related data
It is to be generated using random number operation, data rule is met after operation, communication is all different every time；Transmitter is for all
Valid data carry out operation, generate " data encryption basis code character " the relevant data generated with this communication operation, synthesize
Data.After receiver receives data, pointer, encryption algorithm code number and data encryption basis code character are extracted first, by reverse
Operation restores valid data, completes normal communication.It is understood that receiver needs certain caching storage, refer to receiving
Data, which can be carried out, after three needle, encryption algorithm code number, data encryption basis code character partial datas cracks reduction work.Currently
The MCU operational capability of equipment platform have it is more than needed, carried out while operation it is other operation will not influence its processing speed, it is right
The operation of equipment has not significant impact.
To use a data cryptography infrastructure code character, i.e., for two dimensional encryption: the Encryption Algorithm of formulation should be two-dimentional operation,
Valid data itself and data encryption basis code character are substituted into operation, to reach higher secrecy effect.Such as Fig. 2 institute
Show there are the structures such as lead code, pointer, encryption algorithm code, valid data, data encryption basis code character, end code in data transmission
At.When there is data to need to transmit, transmitter needs operation to generate pointer, encryption algorithm code, and encryption algorithm code is put
It sets in the position that pointer is specified.After the completion of above-mentioned work, the data Z for sending data is calculated according to the Encryption Algorithm randomly selected,
It is as shown in Figure 3:
A=f (A ', y) is corresponded in Fig. 3, Encryption Algorithm are as follows:
A1=f (A '1, Y1)
A2=f (A'2,Y2)
……
C7=f (C'7, Y7)
……
It should be noted that in formula, A '0、A’1... it is primary data, A0、A1... it is encryption data.All encryption numbers
According to its primary data is equal and the basic code character of data encryption forms multidimensional function relationship.It, will by multidimensional (polynary) cryptographic calculation
Operation result A0、A1... instead of primary data, generate encryption data.
In the packet, data encryption basis code character can be 1 group (8) or multiple groups, such first formula
Polynary operation can be upgraded to by two-dimentional (binary) operation, the confidentiality of encryption is stronger.In the data packet for generating encryption, transmitter
Send this data；It when receiver recognizes data, receives and is cached, add receiving pointer, encryption algorithm code number, data
After close basis code character, it can according to need and start to decrypt operation, or decrypt operation after receiving completely.Above-mentioned operational process can join
It examines shown in Fig. 4.
In addition it is also necessary to which explanation, is carrying out multidimensional cryptographic calculation using dynamic multi-group data cryptography infrastructure code character
When, operation is decrypted using traditional " method of exhaustion " and can not, it is necessary to really understand all related datas encrypted, include
Operation can be just decrypted in algorithm, pointer, data encryption basis code character.A kind of dynamic encryption of digital signal data of the disclosure
Method makes full use of the operational capability of data itself and hardware, carries out Dynamic and Multi dimensional cryptographic calculation, prevents data from being used " poor
The hardballs such as act method " crack by force.The dynamic encrypting method based on digital signal data that the disclosure proposes can be used extensively
In wired data transfer, the transmission of local wireless network data, similar carried out in the public public networks such as 4G, NB-IoT, 2G (GPRS etc.)
The data for having security requirements transmission.Because its algorithm dynamic is a variety of, basic data position is also that dynamic is specified, is aided with encryption generation
The non-regularity variation of code number, secrecy effect with higher.
