摘要
本文首先研究了IC卡数据存储的特点 ,依据存储特点将IC卡划分为单数据应用分区IC卡、单分区IC卡和多分区IC卡三类。给出了IC卡的只读区、控制区、数据区和分区的定义 ,并在此基础上构造出单张IC卡的数据存储模型和对应的数据结构。为了能够描述任意类型的IC卡 ,本文进一步提出IC卡的统一数据模型和对应的数据结构 。
In this paper, the data storage characteristics of IC cards are discussed first. According to the characteristics, IC cards are divided into three types:the single application data area IC card, single area IC card, and multiple area IC card. Meanwhile, the definitions of read-only area, control area, and data area are given. For the purpose of presenting a specified kind of IC cards and any kind of IC cards, the data storage model of single area IC cards and the uniform data storage model of any IC cards are constructed. Meanwhile, the data structures for both models are defined. Also, the data structure of the area information table and the algorithm of accessing data are given.
