Compared with Goodix encryption, GRPLT Lite Config Tool customized firmware encryption allows users to adopt customized algorithms and write the keys generated by customized algorithms into GR551x System-on-Chips (SoCs), to independently control encryption logics. During customized firmware encryption application, users can deduce the correctness of the keys according to the encryption algorithms, to ensure smooth operation of the encryption firmware as well as the security of user products.
