M66 protect the transfer of information via FTP

Is it possible to protect the transfer of information via FTP over a serial channel.
How to protect the channel between the controller and the modem. Is it possible to write the username and password in the module in advance? if not, are there any plans?

Hi,

Is it possible to write the username and password in the module in advance?
====No.
We cannot pre-write your FTP username and password into the firmware.
The user name and password should still be inputted by you.
And also there is no encryption mechanism between the MCU and module UART communication or some kind of security which needs user name and password.

How about this? See below description:

AT+QCFG=“ftp/encrypted”[,<0-1>] ===this means enable the encrypted the username and password with AES.
At+qftpcfg=ftp/encrypted,1

MCU: encrypted the username and password, for example: select the encrypted methord is AES.
for example:
username: Ftp_UserName
AES: pass AT+CGSN to get the module’s IMEI: 869379040022020 (or Combination of IMEI and IMSI)
the encpypted username is: U2FsdGVkX18f/REjNBNx4xmKzAYbsHZoDvkjxxx+UjQ=
password: Ftp_PassWord
AES: pass AT+CGSN to get the module’s IMEI: 869379040022020
the encpypted passowrd is: U2FsdGVkX18auBxiqR5xD/jTk0NUtbctjhD8u5M5CIM=

   AT+QFTPUSER="U2FsdGVkX18f/REjNBNx4xmKzAYbsHZoDvkjxxx+UjQ="
   AT+QFTPPASS="U2FsdGVkX18auBxiqR5xD/jTk0NUtbctjhD8u5M5CIM="

Module: decrypted also select the AES, and pass select the IMEI
username: U2FsdGVkX18f/REjNBNx4xmKzAYbsHZoDvkjxxx+UjQ=
decrypted: Ftp_UserName
password: U2FsdGVkX18auBxiqR5xD/jTk0NUtbctjhD8u5M5CIM=
decrypted: Ftp_PassWord
