我有一个Gemalto Top DL v2 java 卡。当我list查看内容时，卡中加载了很多包：

GlobalPlatformPro:> gp -visa2 -key 47454D5850524553534F53414D504C45 -list

现在，我想删除未使用的包：

问题是为什么我不能删除它们并释放我的卡的内存？

你怎么确定这些包没有被使用？小程序可以设计为使用单独的库和/或服务。这些库/服务在 GP 中有自己的 AID，但您首先需要删除所有小程序实例和小程序模块 - 按此顺序 - 才能删除它们。

很多卡都在 ROM 中预装了软件。ROM 掩码中的空间不能用于其他任何用途。删除这些模块不会释放很多资源。如果删除成功，您基本上只会从注册表中删除 AID。如果您想上传同一库的新版本，这可能很有用，但否则不会有太大的不同。

AID 和 RID 的解释

AID 由两部分组成：一个 5 字节的 RID 和一个可变大小的扩展 - 称为 PIX - 到标识实体的 RID。此实体仅在应用程序 DF 中，但对于 Java Card 模块也由 AID 标识。

现在我已经获得了 RID 的列表，所以：

  • A000000018434D00安全域来自 Gemplus（现为金雅拓）；
  • A0000000620001, A0000000620002, A0000000620003, A0000000620101, A000000062010101, A0000000620102,A0000000620201都是 Sun（现在的 Oracle）模块；它们包含对基本 Java Card 运行时的扩展；
  • A0000000030000是旧VISA RID下的卡管理器；
  • A000000018100201,A000000018100101是金雅拓的扩展模块或小程序；
  • A00000015100是全球平台AID下的卡管家；

A0000000030000AID 正在逐步淘汰 - VISA 是 Open Platform 的创始人，现在是 Global Platform 。GP 现在应该使用自己的 RID。

笔记：

  • 库只是代码和常量，服务包含可以通过对象共享机制使用的状态；
  • 很明显：对于特定卡，您可能需要联系您的供应商以了解其配置方式。
