[0002] Information security storage and transmission technology refers to a series of technologies and methods used to protect data from unauthorized access, theft, tampering or destruction during storage and transmission. These technologies are designed to ensure the confidentiality, integrity and availability of data to prevent data leakage, tampering or loss. Information security storage and transmission technology involves multiple security mechanisms such as encryption, access control, identity authentication and secure transmission protocols to ensure that data is fully protected during storage and transmission.

[0003] Existing information security storage and transmission technologies include many applications, and current mobile devices usually have a password saving function, which can save user account passwords of various APPs to provide users with convenient application services, allowing users to log in to applications faster, but conventional security storage and transmission technologies are easily intercepted. If a user's mobile phone is lost or hacked, there is a risk of account passwords being stolen. Quantum communication technology can well ensure the security of application keys, but existing mobile quantum key communication technologies usually use U disk or TF card as key carriers, resulting in the use of mobile quantum key communication technology is not convenient enough, and users are difficult to combine with mobile devices. For example, in the patent application with publication number CN114218555A, "Enhanced password management APP password security strength method and device, storage medium" is disclosed. This scheme encrypts, transmits and stores APP passwords through conventional encryption methods. When APP passwords are transmitted through ordinary channels, there is a risk of being stolen and easily intercepted by malicious software, resulting in the leakage of users' APP passwords.

Among them, when n=1, 4, 6, 7, 8, 9, 10 or 12, signals with the same polarization are output, then S is extracted. 1 , S 4 , S 6 , S 7 , S 8 , S 9 , S 10 and S 12 The observed result, i.e. the 1st, 4th, 6th, 7th, 8th, 9th, 10th and 12th digits in the measurement result "010010011011", gives the unique key 00001101; The application key encryption unit is used to encrypt the application key using a dedicated key to obtain an encryption key; The application key encryption unit is configured with an application key encryption policy, which includes: Connected to the user's SIM card, for the APP in the user's mobile device, the application key to be stored is marked as a key to be stored; Number the elements in the stored key from left to right, using the symbol P i Indicates, where i is a non-zero natural number and i is the serial number of P. According to ASCII encoding, P i Convert to binary data and get Ei ; In practical applications, in this embodiment, unlike the existing mobile quantum key communication technology that uses a USB flash drive or a TF card as a key carrier, in this embodiment, a SIM card is used as a key carrier to construct a quantum SIM card, thereby realizing the convenient application of quantum communication on mobile devices; in this embodiment, it is detected that the user needs to store the login password of application A, and the application key obtained is "aB123Xy", and P is obtained by numbering. 1 To P 7 They are a, B, 1, 2, 3, X, and y, which are converted into binary data to get E. 1 To E 7 They are 01100001, 01000010, 00110001, 00110010, 00110011, 01011000 and 01111001 respectively; The elements in the unique key are numbered from left to right, using the symbol R h Indicates, where h is a non-zero natural number and h is the serial number of R, the maximum value of h is marked as H; From left to right, i The elements in E are numbered and represented by the symbol T(i,j), where j is a non-zero natural number and (i,j) is the serial number of T.

The last digit is 0, that is, G(1,1)=0. Analyze them one by one and calculate T(1,8)+R 8 When , since it is a binary calculation, the calculation result is 1+1=10, and the last digit is 0, that is, G(1,8)=0. By analogy, all G(i,j) are calculated. G(i,j) is grouped according to i, and the encryption key is formed by sorting them in ascending order according to j. Grouping according to i, G(1,j) is 01101100, where the first digit represents G(1,1) and the last digit represents G(1,8). Similarly, G(2,j) to G(7,j) are 01001111, 00111100, 00111111, 00111111, 01010101, and 01110100 respectively. The quantum state conversion unit is used to convert the encryption key into a quantum state; The quantum state conversion unit is configured with a quantum state conversion strategy, which includes: The horizontal polarization basis, vertical polarization basis, 45° polarization basis and 135° polarization basis are collectively referred to as angle polarization basis. The photon sequence is obtained and the angle polarization basis in the photon sequence is numbered from left to right. d It means, where d is a non-zero natural number and d is the serial number of U; The horizontal polarization base represents 0, the vertical polarization base represents 1, the 45° polarization base represents 1, and the 135° polarization base represents 0; In practical applications, the photon sequence is "horizontal polarization base, vertical polarization base, 45° polarization base, 135° polarization base, vertical polarization base, 135° polarization base, horizontal polarization base, vertical polarization base, 45° polarization base, horizontal polarization base, 135° polarization base and 45° polarization base", numbered U 1 toU 12 , since the horizontal polarization basis represents 0, the vertical polarization basis represents 1, the 45° polarization basis represents 1, and the 135° polarization basis represents 0, therefore U 1 toU 12 It can also be expressed as 0, 1, 1, 0, 1, 0, 0, 1, 1, 0, 0, and 1; For any value of i, starting with j=d=1, compare G(i,j) with U d Are they the same? If they are the same, a valid data signal is output; if they are not the same, an invalid data signal is output; If the output data is valid, then U d Mark it as Q(i,d), increase j and d by 1 and compare again; if the output data is invalid, then U d Mark it as V(i,d), and re-align it at the same time d+1; The linear polarization basis and the diagonal polarization basis are collectively referred to as the observation basis. According to the order of d from small to large, U d Is it Q(i,d) or V(i,d)? If it is Q(i,d), choose the same as U d The same observation basis is marked as K(i,d). If it is V(i,d), then select the same observation basis as U d Different observation bases are marked as K(i,d); According to different values ​​of i, different observation sequences are composed of K(i,d); In practical applications, take i=1 as an example, start with j=d=1, and compare G(1,1) with U 1 , then G(1,1) and U 1 are all 0, output data valid signal, and U 1 Mark it as Q(1,1), increase both j and d by 1, and compare G(1,2) with U 2 , then G(1,2) and U 2 are all 1, output data valid signal, and U 2 Mark it as Q(1,2)=1, and so on. When j=d=6 is analyzed, compare G(1,6) with U 6 , then G(1,6) and U 6 If they are not the same, the data will be invalid and the U 6 Mark it as V(i,6), and compare d+1, G(1,6) with U 7 , then G(1,6) and U 7 If they are not the same, the data will be invalid and the U 7 Marked as V(1,7), and analyzed in this way, we finally get d=1, 2, 3, 4, 5, 8, 10 and 11 as Q(i,d). Since the photon sequence is “horizontal polarization basis, vertical polarization basis, 45° polarization basis, 135° polarization basis, vertical polarization basis, 135° polarization basis, horizontal polarization basis, vertical polarization basis, 45° polarization basis, horizontal polarization basis, 135° polarization basis and 45° polarization basis”, when d=1, 2, 3, 4, 5, 8, 10 and 11, the observation basis that is the same as the corresponding position in the photon sequence is selected, and when d=6, 7, 9 and 12, the observation basis that is different from the corresponding position in the photon sequence is selected, and the observation sequences K(1,1) to K(1,12) are “linear polarization basis, linear polarization basis, diagonal polarization basis, diagonal polarization basis, linear polarization basis, linear polarization basis, diagonal polarization basis, linear polarization basis, linear polarization basis, linear polarization basis, diagonal polarization basis and linear polarization basis” respectively.

The transmission of the encryption key is the transmission of the photon sequence. When the encryption key needs to be decrypted, it is transmitted through the photon sequence. In actual applications, the photon sequence and the observation sequence are stored. The observation sequence only exists in the user's mobile device, and the photon sequence is stored in the key storage terminal. Only by observing the correct photon sequence through the correct observation sequence can the correct encryption key be obtained, and the acquisition process cannot be monitored or intercepted, which ensures the absolute security of the encryption key. In addition, only the photon sequence corresponding to the user is saved in the key storage terminal. When the data is saved by a third party, the third party cannot know the specific content of the saved data. In the existing third-party information security storage technology, the third party can usually know all the saved content.

[0020] The quantum key analysis module is used to verify the user's identity information and then analyze the quantum key when the user needs to use the application key; The quantum key analysis module is configured with a quantum key analysis strategy, which includes: When a user needs to use an application key, the user's identity information is verified, including face recognition and fingerprint recognition; After verification, the photon sequence and observation sequence are obtained, and the observation sequence is marked as Y for any value of i. i , according to the photon receiving sequence and photon sending sequence to verify the exclusive key, by observing the sequence Y i Verify with the photon sending sequence to obtain the encryption key G(i,j); The encryption key is then parsed using a dedicated key to ultimately obtain the user's application key; In practical applications, the existing face recognition technology and fingerprint recognition technology are used to verify the identity information. After the verification is passed, the observation sequence is read from the user's mobile device, and then the photon sequence corresponding to the user is extracted from the key storage terminal. In this embodiment, taking i=1 as an example, when i=1, the observation sequence corresponding to K(1,d) is "linear polarization basis, linear polarization basis, diagonal polarization basis, diagonal polarization basis, linear polarization basis, linear polarization basis, diagonal polarization basis, linear polarization basis, linear polarization basis, linear polarization basis, diagonal polarization basis and linear polarization basis", and the photon sequence is "water A plane polarization basis, a vertical polarization basis, a 45° polarization basis, a 135° polarization basis, a vertical polarization basis, a 135° polarization basis, a horizontal polarization basis, a vertical polarization basis, a 45° polarization basis, a horizontal polarization basis, a 135° polarization basis and a 45° polarization basis". Based on the rules in the exclusive key generation unit, the encryption key G(1,j) is observed to be 01101100, and so on. The encryption key G(i,j) is analyzed and obtained. Parsing the encryption key with the exclusive key is actually the inverse operation of encrypting the application key with the exclusive key. Therefore, no specific examples are given in this embodiment.
