SE050 Transient Object Export

wami — Thu, 31 Oct 2019 19:58:42 GMT

Hi there,

I have seen in the APDU-Guide there is a function and policy that allows export of an transient object using an "randomly generated but persistent stored AES Key" which will be used to encrypt the object before export.

Is there any way to define a "Transport Key" for this? I have the requirement to backup an generated key if the board needs to be replaced at any time.

Any Idea how to make this possible?

Thanks in Advance.

Michael

Hello Michael,

Do you mean you want to set up the "randomly generated but persistent stored AES Key" manually? Please kindly clarify.

Have a great day,
Kan

Yes absolutely.

I want to be able to Import exported objects in other SE050 Chips.

Hi Michael,

This AES key is automatically internally generated and handled. No user interaction is possible.

Have a great day,
