A rapid transit system transit system great p has four times the fare table, providing four different fares, fare table by the MRT central computer management. Tickets Table I: for general use ticket great p and group ticket fare Table II: Tickets for other ticket types using Table 3: Reserved (for future use) Fare Table IV: Reserved (for future use) the structure of the MRT fare table: b. Bus fares are based on vehicle great p type, cardholder identity to set ticket types, can provide great p a variety great p of fare. Bus fare sheet structure: the identity of the cardholder: 16 kinds (students, the elderly, children ........ etc.) vehicles: air-conditioned buses, night buses, tour bus ticket types: general ticket, holiday tickets and travel tickets 4 share. the use of electronic purse wallet share ways to make the system with cash, debit card, credit card and debit card transfer value-added features. 5 passenger ticket types held regular recognition system, the meter, metering, and other 254 kinds of specific sections IC Smart Card, offers visitors a variety of options.

II, a system security mechanisms, travel card system secure transaction process: when the cardholder travel great p card system ticket card transactions must be completed each other's ticket and the ticket is correct equipment certification can continue great p after the completion of the transaction, and the transaction After the transaction data generated in the transfer must ensure that its contents are not tampered with the process, to be able to complete the liquidation CCHS ensure data consistency and integrity of the content of their transactions secure transaction process as shown below: Second, the base code of works: a kind of base codes: between (1) ticket and ticket-based mutual authentication code equipment used (2) when the base code used to generate MAC (3) to generate diverse base when the base code used in code detailed description of various types of base code is as follows: 2 votes mutual authentication between the card and the ticket equipment: Memory cards are divided into several Sector, each Sector has a key A and key B, and ticket card reader of each Sector, the value of the card must first confirm the key A and key B of whether the ticket machine in the key A, key B's value is the same, if the same, in order to continue to complete the transaction Key A: Read When information or chargeback with, Key B: use when writing or bonus. 3 in each transaction data uploaded from the device to the CCHS liquidation great p recount, recount equipment stored in the device will use the MACing key with the transaction data content into the MAC algorithm formula to calculate the MAC of the transaction , Append data on the sum, together sent CCHS, while CCHS's computer also keeps MACing key, when the transaction data to the CCHS, CCHS will also MACing key and the contents of the transaction data into the MAC calculation calculation method, the software calculates the MAC after the transaction, the transaction data with MAC upload ratio right, if equal, then the information is correct, has not been tampered with. MAC = MAC calculation formula (transaction data, MACing key) device to the CCHS ticket transaction data format: 4-key diversification (Key Diverisfy) ticket kaki code diversification: Master key A and Master key B for the ticket great p mutual authentication great p between the device and the ticket with the base code, so Master key A and Master key B must be separately stored in the ticket and the ticket machine, and in fact will host Master key code stored in the ticket is a very dangerous thing because staffing a ticket, a high probability of the host code to crack, so to avoid this condition, you must use the ticket code diversified technology Kaji, the actual tickets stored on each card in the base code key A and key B's are not the same value (called Diverisfy key A, key B), even if there is a ticket great p card-based codes are cracked, nor will all vote card base code to be cracked. Equipment base code diversification: MAC device great p must be added when uploading data for each transaction, so in theory, the device should be there Master MACing key transaction data to calculate each of MAC, in fact, the Master MACing key stored in the device very dangerous, because if a ticket machine MACing key is cracked, it can lead to all ticket MACing key equipment are cracked, it must also use the base code diversified technology, storage devices MACing all recount The key is not the same value (called Diverisfy MACing key). Diversified generating facilities MACing key ways:
