Embodiment Construction

[0064] In order to make the purpose, technical solution and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.

[0065] The overall module composition and interaction of the present invention are as follows: figure 1 shown.

[0066] The key center 110 is the core server of the system and also the security center of the entire system, and is composed of an authentication module 111 , a key management module 112 and an authorization module 113 . The card making / code making device 101 and the card reading / code reading device 131 are called the terminals of the system, and the key center 110 assigns a unique number to all terminals, then generates a pair of RSA public and private keys, and distributes the private keys to the terminals as Its unique identity key, while saving the public key in the database of the key center. This pair of RSA public...

Abstract

The invention relates to IC cards and two-dimension codes and discloses a data safety storing method suitable for IC cards and two-dimension codes. The method comprises the steps of (1) terminal registering, (2) authentication, (3) card/code generating and (4) card/code reading. A symmetric key and an asymmetrical key are combined for use, only the data storing function of the IC cards and the two-dimension codes is used, a data encryption function is completely completed by an upper layer software system, accordingly, limiting from the types and inner achieving of the IC cards is avoided, and limiting from the types of the two-dimension codes is avoided. Each card/code generator and each card/code reader are provided with unique identity keys, a key center is used for distributing different encryption keys during each-time encryption, and the key center carries out decryption authorization on the card/code reader. The forward safety of the keys can be well guaranteed, right control particle size is well refined, and accordingly data safety is enhanced.

Description

technical field [0001] The invention relates to an IC card and a two-dimensional code, in particular to a data safe storage method suitable for the IC card and the two-dimensional code. Background technique [0002] IC card is an integrated circuit card (Integrated Circuit Card), also known as a smart card (Smart card), a smart card (Intelligent card), a microcircuit card (Microcircuit card) or a microchip card, etc. It is a microelectronic chip embedded in a In the ISO7816 standard card base, it is made into a card form, and the information is stored through the integrated circuit in the card. The communication method between the IC card and the reader can be contact or non-contact. According to the communication interface, the IC card is divided into Contact IC Card, Non-Contact IC and Dual Interface Card (1. Luan Jiahui, Yang Fang, Zhou Xiu. Present Situation and Application of IC Card Technology [J]. Agricultural Mechanization Research, 2003, 03:189-190; 2. Yang Zhaomin ...
