Secured OTK

What is an OTK ?

an OTK is a One Time Key

It is a secret used only once and shred by two parties

Why do they need to be cared for ?

One time Keys used by our random hash signatures need to be secured

as their theft would enable the generation of false e-signatures

A fake firmware could enable the key theft

How do we secure the keys

Keys are deleted upon any non authorised firmware update
