Abstract

The invention discloses an encryption method and a decryption method of remote card-issuing data transmission of a financial IC card and a financial social security IC card, and the encryption method and the decryption method are used for improving the security in the data transmission process. The encryption method and the decryption method comprise the following steps: a server firstly encrypts a first original key and a second original key to obtain final encryption keys, and adopts the encryption keys to encrypt the card-manufacturing data corresponding to the IC card number to obtain encrypted messages; a client obtains the encrypted messages, a second-stage key scatter factor and the second original key which are sent by the server, encrypts the second original key by the second-stage key scatter factor to obtain a decrypting key, and decrypts the encrypted messages by the decrypting key to obtain the card-manufacturing data; and thus, in the encryption and decryption processes provided by the invention, the higher security of the encrypted messages in the transmission process are guaranteed by a second-stage scattering encryption manner, and the security is greatly improved.

Description

technical field [0001] The invention relates to the field of IC cards, more specifically, to a method for encrypting and decrypting data transmission for remote card issuance of financial IC and financial social security IC cards. Background technique [0002] Major banks have become new card issuers of financial IC and financial social security IC cards. However, due to the short time and heavy tasks, the card production business needs to be transferred to the factory for card issuance. [0003] At present, there are three ways to send bank card data from the bank to the card factory. The first method: copy the bank card data to the card punching machine of the card factory through a mobile device such as a U disk; the second method: send the bank card data through the network Send it to the card factory in plain text before issuing the card; the third method: encrypt and package all the bank card data as a whole, and transmit it to the card factory to make the card through...
