Abstract

The invention discloses a smart card dynamic password authentication system which is used for the field of smart cards and is used for solving the data security problem of the traditional smart card. The system comprises a smart card, a port manager, a central processing unit (CPU) and a remote server, wherein the CPU is electrically connected with the smart card by the port manager; the CPU comprises a dynamic password generation module; the port manager is used for providing a communication interface for the smart card and the CPU; the CPU is used for activating the dynamic password generation module to generate a dynamic password when receiving a read / write command of a card reader on the smart card; and the remote server is used for producing a random password at definite time and authenticating the dynamic password to verify whether the random password is the same with the synchronously generated dynamic password. By using the dynamically generated password to encrypt and verify the read / write process of the smart card, the data security and trading security of the smart card are effectively improved.

Description

technical field [0001] The invention relates to the field of IC smart cards, in particular to a smart card dynamic password authentication system and a smart card dynamic password authentication method. Background technique [0002] IC card (Integrated Circuit Card) is another new type of information tool after the magnetic card. In some countries and regions, IC card is also called smart card, intelligent card, micro circuit card ( microcircuit card) or microchip card, etc., it is to embed a microelectronic chip in the card base conforming to the ISO7816 standard to make a card form; it has been widely used in many fields including finance, transportation, social security, etc., mainly for public transportation , ferry, subway automatic toll system, also used in access control management, identification and electronic wallet. [0003] Smart cards are semiconductor cards that use microelectronics technology to store and process information. According to the structure of th...
