This is a hierarchical structure diagram of the base code. The base code management system is mainly divided into a four-level structure. The top layer is the main base code 10, and the base is the base encryption base code of the subsystem. 101, 1 11, 121, communication base code 5 102, 112, 122, authentication base code 103, 123, work base code 104, 124, ticket card base code 113, and ticket card diversification base code 114. Three branches, one is provided by the main base code 10 for system encryption, which becomes the base code encryption base code 101, which is then converted into the communication base code 102 and provided as the authentication base code 103 and the working base code 104; the other is provided by the main base. Code 10 provides system encryption, which becomes the base code plus 10. The secret base code 111 is then converted into a communication base code 112 and is provided as a ticket card base code 113 and a ticket card diversified base code 114. Another system is provided by the main base code 10 for system encryption. The encrypted base code 121 becomes the communication base code 122 and is provided as the authentication base code 123 and the working base code 124. Please refer to Figure 2, Figure 3 and Figure 4. Based on this hierarchical 15 base code structure, this base code management system server 11 is developed. It consists of hardware security module 12, system management 15 units, base Code generation and maintenance management 16 units, base code storage management 17 units, security control card 14 and registration and issuance management of terminal equipment security modules 18 units and 1C card reader 13 and each unit is based on Chinese national standards (CNS) A4 specification (210 X 297 mm) (Please read and read the notes on the back before filling this page) -------- Order --------- line 981 981 PA880520. DOC-7/13 A7 B7 V. Description of the Invention (f) The functions are described as follows: (1) Hardware security module 12 This hardware security module has a mechanism to prevent theft of base code data, and there is improper damage When disassembling and disassembling, the internal data will be automatically deleted. It is used to generate and store the base code, perform various encryption and decryption operations and mutual authentication with the security control card. The procedures for mutual authentication are shown in Figure (3) and Figure (4). ). (II) System Management Unit 15 This unit sets the system function permissions. There are different system execution functions according to different permissions. The system is divided into three high-level and low-level permissions. 10 The highest permission is the execution of security card management. , Base code generation and maintenance management, and base code storage management functions. The execution of this highest authority is controlled by two people each with a highest authority security control card. To perform the functions of this authority, two people must be present at the same time. Only the next level of authority can execute the terminal device security module issuance management function; the minimum authority is the ability to change the security control card secret 15 codes. (III) Base code generation and maintenance management 16 units This unit contains the generation, transmission, update and destruction of base code. The base code generation is generated by the random random number generator in the hardware security module and generated in the base code. Intermediate states and values cannot be accessed in clear text or other unprotected form20, which can prevent the leakage of base codes due to human factors. The base code is transmitted using triple control. First, the base code encryption of each subsystem (such as the card issuing system and value-added system) is encrypted into A code and B code, which are stored in two security control 1C. The cards (A and B cards) are kept by two security personnel, and the data in the A and B cards are controlled by the PIN; other basic paper sizes to be transmitted apply the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read the notes on the back before filling out this page) Order --------- Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 491981 PA880520.DOC-8/13 Α7 Β7 V. Description of the invention (b) Codes (such as the communication base code, authentication base code and work base code of the terminal equipment and card issuing equipment, and the base code of the ticket card) are stored after being encrypted by the base code encryption base code of each subsystem In another security control 1C card (C card), it is kept by the third security control personnel, and the base code transmission is carried out by three security control personnel holding three security control 1C cards 5 at the same time to the security control of each subsystem Personnel, the security control personnel on both sides shall be restored by the A card and the B card. Desired base code, the base code to complete the transfer. During the use period of the base code, if the original base code is likely to be broken, or the base code's use period expires, the base code should be updated to the new base code, and the old base code will be destroyed. 10 (IV) Base code storage management 17 and the main base code storage of the split-unit unit are stored in the write-only memory of the hardware security module, and are divided into five parts by using the split-secret method. The personnel are kept separately. Only when more than three people arrive, the main base code can be restored. The other base codes are encrypted in the main base code and stored in the hardware security module and database 15. The method of separating secrets is briefly described below. Assuming that M is the main base code to be divided, take a first- and second-order polynomial F (x) = (a χΛ2 + bx + Μ) mod P where a and b are arbitrarily selected coefficients. ; P is a large prime number greater than a, b. By choosing five different points in this second-order polynomial, you can get five subbases with a score of 20. K /-F (X /) / = 1,2, .., 5 When three of the subbase codes are known, then M can be obtained by LaGrange's internal difference polynomial. When the base code management system is damaged, causing the base code to be damaged, this unit can be used in accordance with the Chinese National Standard (CNS) A4 specification (210 X 297 mm). -------------, (_Please read the notes on the back before filling this page)
