需要帮助来了解Mifare [英] Need help understanding Mifare

问题描述

大家好

首先，我首先要说的是，在发布此问题之前，我已经对此主题进行了广泛的搜索.我只问那些有使用这项技术经验的人.因为我绝对没有零经验.

我有以下问题:关于desfire EV1(8kb)
键a和键b的意义是什么?
desfire初始化过程是什么?
当我从卡中读取数据时，应该期待什么数据结构?
如何将自定义值编码到卡扇区中以及如何工作?
对读卡器进行编程以读取卡扇区时要寻找什么?

我正在寻找类似解释的机制，例如:
要对卡进行编码，请确保. . . ，然后执行此命令，以此类推.

我不是真正地在寻找代码，只是将字节和位分解开来的更高级的解释(在Google上足够多了).

但是，如果您可以向我介绍STEPS的文章，那么程序员在进行此操作时应该采取这些步骤，请告诉我.

提前感谢

Hi all

First and foremost I just want to say I have googled this subject extensively before posting this question. and I am asking only those who has experience in working with this technology. Because i have absolute zero experience in it.

I have the following questions: Regarding desfire EV1 (8kb)
What is the significance of the key a and key b ?
What is the desfire initialization procedure ?
What data structure is to be expected when i read from the card ?
How to encode a custom value into the cards sectors and how it works ?
What to look for when programming the reader to read the cards sectors ?

I am looking for a mechanic like explanation for example:
To Encode a card make sure that . . . , then do this, run this command ect.

I am not really looking for code just a more high level explanation short of breaking apart the bytes and the bits (there are more than enough of that on google).

but if you can point me in the direction of a article of STEPS a programmer should take when working with this please let me know.

Thanx in advance
