为什么我不能从我的JavaCard中删除未使用的包？

Question

我有一个Gemalto顶级DL v2 java卡。当我list内容时，卡中装载了大量的包：

GlobalPlatformPro:> gp -visa2 -key 47454D5850524553534F53414D504C45 -list
AID: A000000018434D00 (|.....CM.|)

     A000000018534441 (|.....SDA|)

AID: A00000015100 (|....Q.|)
     ExM LOADED: (none)

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卡的内存？

Answer 1

回答

如何确定这些包是未使用的？可以设计一个applet来使用单独的库和/或服务。这些库/服务在GP中有自己的AID，但是您首先需要删除所有applet实例和applet模块--按照顺序--然后才能删除它们。

许多卡包含预先安装的软件ROM.ROM掩码中的空间不能再用于其他任何东西。删除这些模块不会释放很多资源。如果删除成功，基本上只会从注册表中删除AID。如果您想上传同一个库的新版本，这可能很有用，但否则不会有太大的区别。

援助和救援的解释

AID由两个部分组成:一个5字节的RID和一个称为PIX的可变大小的扩展，用于RID标识实体。这个实体只是在应用程序DF中，但是对于Java Card模块也是由AID标识的。

现在我买了一张RID的清单

• A000000018434D00安全域来自Gemplus (现为Gemalto)；
• A0000000620001，A0000000620002，A0000000620003，A0000000620101，A000000062010101，A0000000620102，A0000000620201都是Sun (现在的甲骨文)模块；
• A0000000030000是旧签证下的信用卡经理；
• A000000018100201、A000000018100101是Gemalto的扩展模块或小程序；
• A00000015100是全球平台AID下的卡经理；

A0000000030000国际开发署正在逐步淘汰-- VISA是开放平台( Open )的创始人之一，现在是全球平台( Global )。现在GP应该使用自己的RID。

备注：

• 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:对于一张特定的卡，您可能需要与您的供应商联系，了解它是如何配置的。
