Is there any alternative to ssh/dropbear passphrase for LUKS unlock ?

[hanguofu]

I am referring to s905(x) series SOCs. Is it possible to create  a cryptpasswd at  encrypted OTP  and use it to  unlock root file system on boot ?

If not , is it possible to use  a security chipset such as   ATSHA204  /  DX81C04  /  ZW30I8 / SMEC98SP  to feed s905(x) the key ?

 

 

Regards !
