Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of optical transmission communication, and particularly relates to a dynamic transmission method and device based on quantum noise-like flow encoding. BACKGROUND

[0002] In recent years, with the deepening of the degree of digital networking and intelligence, the rise of ultra-high-definition video, cloud computing and virtual reality services, the number of user access and the amount of transmitted information also show an explosive growth, which puts forward higher requirements for data transmission capacity. At the same time, the quantum computing capacity is also constantly improving, and the transmission information often exists the risk of being illegally eavesdropped and violently cracked, which puts forward new challenges to the security of signal transmission.

[0003] Passive optical network (PON) is widely used in the access network field due to its wide bandwidth, low energy consumption and low cost, and is regarded as the future development trend. PON technology has evolved through several stages, and the currently widely used is orthogonal frequency division multiplexing PON (OFDM-PON). Although the utilization rate of frequency range and time-frequency resources is improved, the downlink broadcast used by PON undoubtedly will produce security problems. At present, the encryption methods of communication system are mainly divided into network upper layer encryption and physical layer encryption. In optical network, the encryption scheme of upper layer, such as using various security protocols, has certain security risks, and with the expansion of user scale, the key management becomes more complex. In contrast, the physical layer encryption technology provides higher security, for example, chaotic laser encryption, which generates chaotic signals by modulating laser with chaotic model, but due to the limited bandwidth, it cannot meet the demand of high-speed optical communication.

[0004] With the development of digital signal processing technology (Digital Signal Processing, DSP), a digital domain encryption technology based on chaotic system is proposed, which is widely used due to its high sensitivity to initial value, randomness of chaotic system, large key space and other advantages. The chaotic encryption method based on DSP technology can disturb multiple different dimensions of the signal to achieve high security transmission. However, most of the current research on chaotic encryption schemes are based on the assumption that the receiver knows the key, which is usually the initial value of the chaotic system and is fixed. For such a scheme, it cannot respond in time when illegal brute force is received, thus causing continuous losses. At the same time, these DSP schemes are directly applied to the transceiver for offline processing, without effectively utilizing the channel characteristics. The quantum noise stream encryption (Quantum Noise Stream Cipher, QNSC) scheme is a novel security scheme that masks the original signal in a high-order QNSC signal represented by multiple basis states, and uses noise to mask the decision level, which cleverly utilizes the channel characteristics. However, the basis state is generated by a linear shift register, and once the front end is cracked, the entire signal will be at great risk of security.

[0005] Therefore, in order to further improve the security of the system, it is necessary to realize dynamic key transmission, which poses a challenge to how to transmit the key together with the data signal without being directly decrypted by illegal eavesdroppers. SUMMARY

[0006] Objective: In view of at least one of the above technical problems, the present application provides a dynamic transmission method and device based on quantum-like noise stream coding, which improves the security performance of key and information transmission.

[0007] The technical scheme adopted by the present application is:

[0008] In a first aspect, the present application provides a dynamic transmission method based on quantum-like noise stream coding, comprising:

[0009] S1, obtaining an initial key and original data to be sent;

[0010] S2, generating chaotic sequences X, Y, Z, U according to the initial key using a 4D hyperchaotic model, and performing binaryzation processing on the chaotic sequences X and Y to obtain binary chaotic sequences R I and R Q ;

[0011] S3, introducing the initial key in binary form into error bits, dividing two different matrices as key real part and key imaginary part, and respectively obtaining key stream real part B I and key stream imaginary part B Q ;

[0012] S4, the original data in binary form is converted into data real part and data imaginary part, and the data real part and the data imaginary part are XOR processed by using the binary chaos sequence to obtain data stream real part E I and data stream imaginary part E Q ;

[0013] S5, according to the data stream real part E I , the data stream imaginary part E Q , the key stream real part B I and the key stream imaginary part B Q , a quantum-like noise stream encryption processing is performed to obtain a quantum-like noise stream encryption signal;

[0014] S6, the subcarriers and symbol points of the quantum-like noise stream encryption signal are scrambled by using the chaos sequence to obtain a scrambled signal;

[0015] S7, the scrambled signal is OFDM modulated and then transmitted in an optical fiber channel.

[0016] The scheme is different from the case where the transceiver end knows the key by default in the past. The key is ingeniously represented as a low-order ground state by using a quantum-like noise encryption scheme. By arranging a plurality of state bases, the 16QAM signal obtained by XOR operation of the original signal and the chaos sequence is masked in a high-order 1024QAM signal. In this way, the noise will mask the level of key judgment during transmission. At the same time, the subcarriers and symbol points of the signal are disturbed in multiple dimensions by using a 4D hyperchaotic system and then transmitted. The key of the present application is actively introduced into error bits and up-sampled. For the legal receiving end, the key can be correctly extracted and recovered demodulated. The illegal receiving end cannot crack the information without knowing the key and the encryption method.

[0017] In a second aspect, the present application provides a dynamic transmission device based on quantum-like noise stream coding, comprising a processor and a storage medium;

[0018] The storage medium is used to store instructions;

[0019] The processor is used to operate according to the instructions to execute the method according to the first aspect.

[0020] In a third aspect, the present application provides a computer readable storage medium having a computer program stored thereon, wherein the computer program is executed by a processor to implement the method of the first aspect.

[0021] Beneficial effects: the dynamic transmission method and device based on the quantum noise-like stream coding provided by the application have the following advantages: the data information and the chaotic sequence are subjected to XOR processing as high-bit bits, the key is introduced into the error bits and then up-sampled as low-bit bits (ground state), and the 16QAM signal is masked in each different state base to realize 1024QAM signal encryption. The four-bit chaotic model is used to perform multi-dimensional disturbance on the bits, subcarriers and symbol points of the signal to improve the security performance, while ensuring high-security and high-performance transmission of the key and information. The application ingeniously uses the channel characteristics for key masking transmission, hides the key in the ground state by a method similar to the quantum noise stream encryption scheme, uses channel noise to mask the decision level, actively introduces error bits to ensure the security of the key, and ensures the high-performance transmission of the key through up-sampling. The 16QAM signal is hidden in the 1024QAM signal to further improve the system security. At the receiving end, a unique demodulation algorithm is used to increase the Euclidean distance, thereby improving the transmission performance of the system. Under OFDM transmission, the subcarrier symbol points are subjected to multi-dimensional chaotic encryption, so that even if the illegal receiving end decrypts part of the key, the correct original signal cannot be obtained.

[0041] In some embodiments, in step S2, a chaotic sequence is generated according to the initial key using a 4D hyperchaotic model, comprising:

[0042] ,

[0043] wherein X, Y, Z, U are state variables, t is time, a, b, c, d, e are system parameters. When a=-0.1, b=-1.2, c=2.3, d=-.17692, e=-2.1, the system is a hyperchaotic system.

[0044] Further, the initial key X0, Y0, Z0, U0 is (0.271234567891357, 0.298765432171369, 0.213579246871357, 0.23467975317246). The partial differential equation of formula 1 can be solved by the fourth-order Runge-Kutta method. The phase diagram of the chaotic model obtained is as shown in Figure 2 From Figure 2 , it can be found that the value ranges of the four chaotic sequences X, Y, Z, U of the model are (-3, 2), (-3, 2), (-3, 2), (-1, 1) respectively.

[0045] In some embodiments, in step S2, the chaotic sequences X and Y are binarized to obtain binarized chaotic sequences R I and R Q , comprising:

[0046] If the X of the chaotic sequence is greater than-0.5, it is 0, otherwise it is 1, to obtain the R I of the binarized chaotic sequence;

[0047] If the Y of the chaotic sequence is greater than-0.5, it is 0, otherwise it is 1, to obtain the R Q.

[0048] In some embodiments, S3, the initial key in binary form is introduced into error bits, and two different matrices are divided as the key real part and the key imaginary part, and the key stream real part B I and the key stream imaginary part B Q As shown in Figure 3 , comprising:

[0049] S31, the initial key is converted into a 256-bit key after being represented by binary and then being converted by series-parallel conversion, and is converted into a 64x4 matrix;

[0050] S32, the 5th column and the 6th column are added on the basis of the 64x4 matrix, wherein the data of the 5th column is the exclusive or result of the 1st column and the 3rd column, and the data of the 6th column is the exclusive or result of the 2nd column and the 4th column; then two different matrices are divided as the key real part and the key imaginary part (the key state base of the I and Q two paths);

[0051] S33, the key real part and the key imaginary part are respectively converted by series-parallel conversion and then up-sampled 240 times to obtain two 1x76800 matrices as the key stream real part B I and the key stream imaginary part B Q .

[0052] In some embodiments, S4, the binary form of the original data is converted by series-parallel conversion to divide the data real part and the data imaginary part, and the data real part and the data imaginary part are processed by exclusive or processing using the binary chaotic sequence to obtain the data stream real part E I and the data stream imaginary part E Q , comprising:

[0053] S41, the binary form of the original data is converted by series-parallel conversion to divide the data real part and the data imaginary part, and the data real part and the data imaginary part are 1x51200 data to facilitate subsequent quantum noise-like stream encryption operation;

[0054] S42, the data real part and the data imaginary part are processed by exclusive or processing with the binary chaotic sequence R I and R Q to obtain the data stream real part E I and the data stream imaginary part E Q . This step ensures that the encrypted signal is uniformly distributed on the constellation diagram.

[0055] Further, the step S42, the data real part and the data imaginary part are processed by exclusive or processing with the binary chaotic sequence R I and R Q to obtain the data real part and the data imaginary part after exclusive or processing, comprising:

[0056] ,

[0057] wherein E I represents the data stream real part and E Q represents the data stream imaginary part, S I represents the data real part and S Q represents the data imaginary part, R I and R Q are binary chaotic sequences, and represents the XOR processing.

[0058] In some embodiments, S5, according to the data stream real part E I , the data stream imaginary part E Q , the key stream real part B I and the key stream imaginary part B Q , performs the quasi-quantum noise stream encryption processing to obtain a quasi-quantum noise stream encrypted signal, including:

[0059] The real part data I = E I + B I of the quasi-quantum noise stream encrypted signal;

[0060] The imaginary part data Q = E Q + B Q of the quasi-quantum noise stream encrypted signal;

[0061] wherein + represents high-low bit combination.

[0062] In this embodiment, the data after the XOR processing is mapped according to the 16QAM rule, and then the quasi-quantum noise stream encryption processing is performed, as shown in Figure 4 is a schematic diagram of the quasi-quantum noise stream encryption principle. The data and the key of the I and Q two paths have been separated and represented (the data stream real part E I , the data stream imaginary part E Q , the key stream real part B I and the key stream imaginary part B Q ) in the previous step, and 64 basic states (3 bits for I and Q respectively) are used to encrypt the 16 QAM data stream (2 bits for I and Q respectively). That is, I or Q has 2-bit data and 3-bit key stream, and a total of 5-bit encrypted signal. In this way, the present application obtains 1024 encrypted symbols (2 5 × 2 5= 32 × 32), 4 bits (I + Q) of information are hidden in it, and the decision level is covered by noise. For I data, in this case, every 8 symbols from left to right correspond to 00, 01, 10 and 11, while for Q data, every 8 symbols from bottom to top correspond to 00, 01, 10 and 11, and the I channel key state base is arranged from left to right in the symbols periodically from 000 to 111, and the Q channel key state base is arranged from bottom to top periodically. Therefore, for example, the combination of data stream (E I , E Q ) = (10, 01) and key stream (B I , B Q ) = (001, 011) generates a quantum-like noise stream encrypted signal (I, Q) = (10001, 01011). That is, in each time slot, the data stream (16 QAM constellation) can be moved with different base states.

[0063] In this embodiment, Figure 5 a scheme for generating an encrypted 16 QAM signal is shown. The chaotic sequences X, Y are used in this application to generate two random 1 × 51200 matrices, and two 1 × 76800 key matrices are subjected to serial-parallel conversion, and finally two 2 × 25600 data matrices representing the IQ two channels and two 3 × 25600 key matrices representing the IQ two channels are obtained. Taking the I channel as an example, in this embodiment, the above-mentioned matrices are divided into 25600 groups, each group has 2 bits of data information high bits after XOR operation and 3 bits of key information low bits (which can be m bits), which are combined to become 5 bits of I channel encrypted signal, and the Q channel is the same. That is, the I and Q data of the encrypted signal are given by (I, Q) = (S I R I + B I , S Q R Q + B Q ).

[0064] In some embodiments, S6, scrambling subcarriers and symbol points of the quantum-like noise stream encrypted signal using the chaotic sequence to obtain a scrambled signal, comprising:

[0065] ,

[0066] wherein Z1, U1 represent the last two digits of the chaotic sequences Z, U, mod(-) is the remainder function, and sort(-) is the ascending order sorting function; after ascending order sorting Z1, U1, the inverse matrix is generated, and then multiplied by the matrix Z1, U1 to generate a scrambling matrix Z2, U2;

[0067] The order of the scrambling matrix Z2 and U2 is equal to the number of subcarriers and the number of symbol points of the quantum-like noise stream encryption signal respectively, there is a 1 in each row and each column of the scrambling matrix, and the remaining elements are all marked as 0, the positions of the 1 in the scrambling matrix Z2 and U2 are extracted to generate a first scrambling sequence and a second scrambling sequence; the subcarriers of the quantum-like noise stream encryption signal are scrambled according to the first scrambling sequence, and then the symbol points of the quantum-like noise stream encryption signal are scrambled according to the second scrambling sequence, to obtain a scrambled signal.

[0068] In some embodiments, S7, the scrambled signal is OFDM modulated and then transmitted in a fiber channel, wherein the OFDM modulation includes:

[0069] The scrambled signal is converted into a time domain signal by inverse fast Fourier transform (IFFT);

[0070] A cyclic prefix and a cyclic suffix are added before and after the time domain signal to obtain a parallel time domain signal;

[0071] The parallel time domain signal is converted into a serial signal by parallel-serial conversion.

[0072] Correspondingly, at the receiving end, OFDM demodulation is performed, and the opposite operation is performed to obtain a received signal that needs to be decrypted after serial-parallel conversion, removal of the cyclic prefix and suffix, and Fourier transform.

[0073] Signal reception and demodulation: for the key transmission scheme, the transmission performance of the key is crucial. If the key cannot be accurately extracted at the receiving end, due to the initial value sensitivity of the chaotic system, an incorrect initial value will generate a completely different chaotic sequence, and decryption cannot be completed, which will result in a large data bit error rate. The present application first uses the decision state base to obtain the correct key to be transmitted, and directly judges the data of the low bits of the IQ two paths, and then extracts the key after obtaining the result. As described above, the key is cyclically sampled 240 times in the above steps, and after the key information is extracted, the information with the most frequent occurrence in each bit of the 240 times is used as the final key, which can effectively ensure the accuracy of the key. In the case of ensuring the accuracy of the key, the present application restores and decrypts the subcarriers and symbol points of the decrypted data.

[0074] For an eavesdropper, because there is no key, it is difficult to know the correct state of the signal under the influence of noise. For a legitimate receiver, it is easy to decode because it has the correct key and encoding method, and it can also assist in decoding through the known state base information. Because the data information is only related to the high-order information, and the low-order information comes from the key information. In Figure 4In the middle, the IQ are all the same state base in 1024 QAM encrypted signal constellation diagram there are 16 positions, that is, in the case of determining the state base, the correct position must be one of them. The traditional 1024 QAM signal decision principle is to calculate the Euclidean distance of each symbol to 1024 positions, and the smallest one is the correct position of the symbol, and the known state base only needs to calculate the distance between the symbol and the 16 same state bases. This decision method can greatly improve the accuracy of decoding. Further, the present application also recovers the position of each constellation point at different state bases according to the symbol (under the same high bit signal), and finally obtains a 16QAM constellation diagram with an 8-fold minimum Euclidean distance expansion compared with the initial signal, as shown in Figure 6 As shown in Figure 2, it is a received 1024 QAM constellation diagram. Figure 7 As shown in Figure 3, it is a corresponding decrypted 16QAM constellation diagram.
