Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. This specific embodiment is a method for storing and managing massive phonebook information by a smart card.

[0029] In order to realize this method, in terms of hardware, it is necessary to use a CPU with high performance and high speed as a central processing unit, and use a FLASH device with a capacity of M class as a data memory. The important high-performance processor can perform encryption and decryption processing and fast query of a large amount of data, providing the basic conditions for large-scale data management and query; large-capacity data storage can provide users with sufficient data storage space. As shown in FIG. 1 , the hardware platform for implementing the smart card of the present invention includes a central processing unit 110 , a data storage 120 and other hardware modules 130 . In the smart card 100 implemented in t...

Abstract

A method for storing and managing mass data of intelligent card includes setting up a databank with functions of basic storage, query, comparison and sequencing on said intelligent card, forming basic structure of said databank by two sets of chain lists, using each node in master chain list to store basic information of each record and initial position of sub-chain list, and using sub-chain list to store different attributes of the same record in structure of identification-length-value.

Description

technical field [0001] The invention relates to the design and application technology of smart cards in the field of microelectronics, in particular to a mass data storage and management method of smart cards. Background technique [0002] With the advancement of social development, people have higher and higher requirements for information security, and smart cards, as a special electronic device, have become more and more sensitive in modern society because of their excellent security and reliability. information carrier. At present, smart cards have been widely used in various fields such as mobile communications, banking, social security, public transportation, and municipal management, and are playing an increasingly important role in the entire social life. [0003] The reason why a smart card can become a carrier of sensitive information is that a CPU with a computing function and a data storage area with a storage function are integrated inside it, and its structure...
