如何向ST25TV02K出示密码？

你好，先生，
在ST25TV02K的数据表中，它介绍了：
“
存在密码命令特异性在执行当前密码命令之前，必须通过命令“Get_Random_Number”获取有效的随机数（参见第6.4.41节：获取随机数）密码必须加密呈现，如下所述可根据要求提供技术说明。
“
但我没有找到'
技术说明
'解释如何加密和呈现密码？据我了解，
1，执行
Get_Random_Number命令获取一个随机数（两个字节）;
2，有些规则用随机nuber和raw密码生成加密密码（四个字节）;
3，使用加密密码执行'Present password'命令。
您能否查看我是否正确并告知第2步的详细信息？
谢谢，
ARNA

Hi Sir,
In the data sheet of ST25TV02K, it introduces that:
'
Present password command specificity Before doing a present password command, it is necessary to obtain a valid random number through the command ‘Get_Random_Number’ (see Section 6.4.41: Get Random Number) The passwords must be presented encrypted as explained in a Technical Note available on request.
'
But I don't find the '
Technical Note
' to explain how the password is encrypted and presented?As my understand,
1, execute
Get_Random_Number command to get a random number (two bytes);

2, some rule to generate an encrypted password with the random nuber and raw password(four bytes);

3, execute 'Present password' command with the encrypted password.

Can you review if I am right and tell the detail for step 2?

Thanks,

Arna
