System and method for sharing security module by card readers

Abstract

The invention discloses a system and method for sharing a security module by card readers. The system comprises a plurality of card readers, a security module sharer and a plurality of PC (Personal Computer) terminals, wherein the card readers are used for reading card operation commands from the PC (Personal Computer) terminals, reading card decryption information from the security module sharer and performing reading writing operation on cards; the security module sharer is used for providing the card decryption information for the card readers; the PC terminals are used for transmitting the card operation commands through the PC terminals and reading the reading and writing operation results of the cards; and a security module is used in the fields of social security, financial transactions and / or identity cards, and the like. By making the card readers share the security module, the structures of the card readers are simplified; meanwhile, a mode of sharing the security mode is adopted, so that the number of the security modules is reduced compared with that for the traditional card readers, and the cost is reduced integrally; in addition, the security module is made independently, so that the security module is easier to maintain, the cost is saved and the utilization efficiency of the security module is increased.

Description

technical field [0001] The invention relates to a system and a method for sharing a security module of a card reader, in particular to a system and a method for sharing a security module of a card reader for a smart card. Background technique [0002] A smart card reader is a device with one or more connectors connected to a PC and receives instructions from the PC to operate the smart card or security module in each connector, used to obtain , modify or store relevant data in the smart card. At present, card readers are widely used in hospitals, banks, transportation, hotels, social security, telecommunications and many other industries. In addition, basically every kind of smart card that involves sensitive data needs to be encrypted and decrypted with its corresponding security module to obtain operation authority or plaintext data. The application includes a security module that reads the information on the face of the ID card, etc. Traditional card readers adopt a on...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the defect that the card reader of the prior art adopts a one-to-one correspondence mode between the smart card and the security module, which leads to the increase of the cost of the card reader and the low utilization rate of the security module, and provides a security Card reader security module sharing system and method in which module is shared by multiple card readers
