[0039] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0041] like Figure 1 As shown, an embodiment of the present invention provides a browser security monitoring system based on quantum encryption, the system comprising:

[0042] The user identity authentication module 100 is used to receive the web page identity authentication information input by the user, and after the identity authentication is passed, the non-encrypted information and the encrypted information subject are displayed on the browsing web page;

[0043] The qubit generation module 200 is configured to receive an encrypted information viewing instruction, randomly generate a qubit string, measure the qubit string to obtain a first measurement result, and send the first measurement result and the qubit string to the browser terminal. When the first measurement result and the qubit string are sent to the browser terminal, the first measurement result is transmitted via a network communication channel, and the qubit string is transmitted via a quantum channel. The browser terminal measurement module 300 is configured to receive the qubit string, measure the qubit string to obtain a second measurement result, and send the second measurement result to the server.

[0044] A shared key generation module 400 is configured to compare the first measurement result and the second measurement result to generate a string of identical random numbers as a shared key, where the shared key is a quantum key;

[0045] The plaintext information encryption module 500 is used to encrypt the user's request information using an encryption algorithm based on the generated quantum key to generate ciphertext; and send the ciphertext to the browser terminal;

[0046] The encrypted information decryption module 600 is used to receive the ciphertext, decrypt the ciphertext using the shared key, and restore the user requirement information corresponding to the encrypted information viewing instruction.

[0047] It should be noted that when a user browses and views confidential information, there is a risk of being eavesdropped, which may lead to information leakage. The embodiments of the present invention are intended to solve the above problem.

[0048] When the user wants to access the intranet webpage of the power grid for related work, the webpage identity authentication information needs to be input, which includes but is not limited to a user account, a password, etc. After identity authentication, non-encrypted information and encrypted information topics are displayed on the webpage. The encrypted information topic is used to indicate the approximate content of the corresponding encrypted information. When the user needs to access the encrypted information corresponding to the encrypted information topic, the encrypted information viewing instruction needs to be input. When the server receives the encrypted information viewing instruction, a quantum bit string is randomly generated. A quantum channel is established between the server and the browser terminal. The quantum bit string is a series of quantum bits generated by a quantum light source. These quantum bits can have different polarization modes and are used to realize key distribution. Each quantum bit is in a specific quantum state, such as a polarization state or a phase state. Then the quantum bit string is measured to obtain a first measurement result. The first measurement result and the quantum bit string are sent to the browser terminal. The browser terminal receives the quantum bit string and measures the quantum bit string to obtain a second measurement result. The second measurement result is sent to the server. At this time, the first measurement result and the second measurement result are compared. When there is a stealing behavior, the quantum state of the quantum bit string will be destroyed, and the first measurement result and the second measurement result will have a large difference. At this time, the ciphertext will not be sent. When the first measurement result and the second measurement result are basically similar, it indicates that there is no stealing behavior. A string of the same random number is generated as a shared key. The shared key is a quantum key. Then, based on the generated quantum key, the user demand information is encrypted through an encryption algorithm to generate a ciphertext. The ciphertext is sent to the browser terminal. The browser terminal receives the ciphertext and decrypts the ciphertext through the shared key to restore the user demand information corresponding to the encrypted information viewing instruction. The quantum bit generation module 200 and the plaintext information encryption module 500 are located in the server. The browser terminal measurement module 300 and the encrypted information decryption module 600 are located in the browser terminal. The server and the browser terminal are both provided with a shared key generation module 400. In this way, based on quantum encryption, it can effectively detect whether there is a stealing behavior in the transmission process of the information, and there is no need to worry about the key being stolen in the transmission process. This key distribution method based on the principle of quantum mechanics provides higher security for encrypted communication.

[0049] As Figure 2 shown, as a preferred embodiment of the present application, the shared key generation module 400 includes:

[0050] The initial consistency rate determination unit 401 is used to publicly compare the first measurement result and the second measurement result to determine the initial consistency rate of the measurement result.

[0051] The communication environment judging unit 402 judges that the communication environment is safe when the initial consistency rate is higher than the set consistency rate, and extracts the same part in the measurement result;

[0052] The shared key generating unit 403 converts the same part into binary information, and generates a series of random numbers as shared keys according to the binary information.

[0053] In the embodiment of the present application, in order to obtain the shared keys, the first measurement result and the second measurement result are compared publicly to determine the initial consistency rate of the measurement result; when the initial consistency rate is higher than the set consistency rate, the set consistency rate is a fixed value set in advance, for example, 96%, the communication environment is judged to be safe, the same part in the measurement result is extracted, and then the same part is converted into binary information, and a series of random numbers are generated as shared keys according to the binary information. Here, an algorithm model for converting the binary information into the keys can be prepared in advance.

[0054] As shown in Figure 3 As a preferred embodiment of the present application, the plaintext information encryption module 500 includes:

[0055] The initial key input unit 501 uses a part of the quantum key as an initial round key, and inputs the initial round key into the AES encryption algorithm.

[0056] The information multi-round encryption unit 502 generates a series of round keys according to the selected key length, and performs multi-round encryption.

[0057] The encrypted ciphertext determining unit 503 generates the encrypted ciphertext, and the ciphertext can be decrypted only by the receiver who holds the corresponding quantum key.

[0058] In the embodiment of the present application, when the user demand information is encrypted based on the quantum key, first, a part of the quantum key is used as an initial round key, and the specific part needs to be set in advance, and the initial round key is input into the AES encryption algorithm; then, a series of round keys are generated according to the selected key length (such as 128 bits, 192 bits or 256 bits), and multi-round encryption is performed. After the multi-round encryption, the ciphertext can be obtained, and the ciphertext can be decrypted only by the receiver who holds the corresponding quantum key. After the receiver receives the ciphertext, the same quantum key and the AES decryption algorithm are used for decryption to restore the original plaintext information. Due to the randomness and unpredictability of the quantum key and the high security of the AES algorithm, this encryption method provides very strong security protection and can resist many traditional password attacks. Figure 4 As a preferred embodiment of the present application, the information multi-round encryption unit 502 includes:

[0059] The initial round encryption subunit 5021 is used to perform an XOR operation on the initial round key and the user demand information to be encrypted to obtain the input for the subsequent encryption rounds;

[0060] The intermediate round encryption subunit 5022 is used to repeatedly apply the AES encryption round function, which includes byte replacement, row shift, column confusion and round key addition. In each round of encryption, the round key is XORed with the state matrix to enhance the encryption effect.

[0061] The last round encryption subunit 5023 is used to perform the last round of encryption, omit the column obfuscation step, and add the round key in the last step of the round function.

[0062] In an embodiment of the present invention, during multiple rounds of encryption, the initial round key is XORed with the user request information to be encrypted to obtain the input for subsequent rounds. The AES round function is then repeatedly applied. This round function includes byte substitution (SubBytes), row shifting (ShiftRows), column mixing (MixColumns), and round key addition (AddRoundKey). In each round of encryption, the round key is XORed with the state matrix to enhance the encryption effect. During the final round of encryption, the column mixing step is omitted, and the round key is added in the final step of the round function. After multiple rounds of encryption, the encrypted ciphertext is obtained. This ciphertext can only be decrypted by the recipient holding the corresponding quantum key. The generation and distribution of quantum keys is inherently a complex and secure communication process that leverages the properties of quantum mechanics to ensure secure key transmission. The AES algorithm is a widely used symmetric encryption algorithm whose security has been widely verified and recognized. Therefore, combining quantum keys with the AES algorithm can further improve the security and reliability of information encryption.

[0063] As a preferred embodiment of the present invention, the system also includes a browsing process monitoring module, and the working steps of the browsing process monitoring module are: after the ciphertext is sent, a quantum bit string is randomly generated at each set time interval, the quantum bit string is measured to obtain a third measurement result, and the third measurement result and the quantum bit string are sent to the browser terminal; the quantum bit string is received, the quantum bit string is measured to obtain a fourth measurement result, and the fourth measurement result is sent to the server; the third measurement result and the fourth measurement result are compared to obtain a subsequent consistency rate, and the subsequent consistency rate is compared with the initial consistency rate. When the subsequent consistency rate is less than the initial consistency rate × k, k is a set ratio value, for example, k is 0.85, it indicates that eavesdropping may occur after the ciphertext is sent, and the communication connection between the browser terminal and the server is interrupted.

[0064] like Figure 5As shown, the embodiment of the present application also provides a browser security monitoring method based on quantum encryption, which comprises the following steps: S100, receiving the webpage identity authentication information input by a user, and displaying non-encrypted information and encrypted information topics on the browsed webpage after the identity authentication is passed;
