Embodiment

[0027] The process of a business interaction between the IC card security keyboard and the PC is as follows:

[0028] 1. The user inserts the IC card into the IC card reader, and the PC obtains the user's information through the TF32A09 chip, and prompts the user to enter a password to verify the user's identity.

[0029] 2. The user enters the password through the keyboard, and then the TF32A09 chip verifies the password through the internal RSA algorithm. If the verification is passed, the user will be prompted to enter the next step. If the verification fails, the user will be prompted to re-enter the password. If the verification fails for three times, the IC card will be locked.

[0030] 3. After user authentication, proceed to the next step. The system prompts the user to select the business transaction type. The user selects the transaction type through the keyboard, enters the transaction amount and other information, and presses the "Confirm" button on the keyboard to...

Abstract

The invention discloses a single-chip based IC (integrated circuit) card swiping keyboard which comprises a main control chip TF32A09 as well as an information security algorithm of the chip and the interface design of the chip. The IC card swiping keyboard carries out information exchange with IC cards by adopting a 7816 interface of the TF32A09 chip, acquires information such as amount of transactions and the like of a user through a keyboard control interface KPP, verifies the identity of the user through the information security algorithm, and then carries out encryption and decryption on data. The single-chip based IC card swiping keyboard disclosed by the invention has high security and abundant stored information, and can be widely applied to the fields of bank cards, identification cards and the like.

Description

technical field [0001] The invention relates to an A, in particular to a single chip-based IC card safe swiping keyboard. [0002] The invention relates to the field of information security, and is mainly applied in the fields of bank cards, identification cards, bus cards, telephone cards, road toll cards and the like. The invention has high security, can ensure the correct encryption and decryption of data during transactions of users, and prevents data from being intercepted illegally. The core is to use the TF32A09 chip and its built-in national secret and international general information security algorithm. Background technique [0003] The keyboard is an important input device of the computer system and an important portal to protect the security of the system. At present, more than 90% of the security keyboards on the market use multiple chips to realize the keyboard and security protection functions. The relevant important data is transmitted throughout the system...
