摘要
本文讨论了当前智能IC卡应用中数据一致性、完整性的维护机制,针对目前维护机制的缺陷,考虑IC卡硬件资源有限的状况,提出一种智能IC卡应用事务机制解决方案和实现事务机制的两种日志记录方式,并重点分析了两种日志记录方式的特点。
In this paper, the current maintenance mechanism of consistency and integrity of the applications in Smart IC cards is discussed. As for the shortcomings of its maintenance mechanism and the limit of its hardware resources, a transaction mechanism that can meet the demands of applications is proposed. Also, two kinds of log schemes to implement the transaction mechanism within the minimal resources for Smart IC cards are offered. Finally, this paper analyzes the characteristics of two kinds of log schemes in detail.
