Web11 mei 2016 · Techniques for hardening the security of running systems often focus on access to memory. An attacker who can write (or even read) arbitrary memory regions will be able to take over the system in short order; even the ability to access small regions of memory can often be exploited. One possible defensive technique would be to encrypt … WebEncrypted image execution in external Flash memory. 1 or 2 slots per image. New image via local loader or USER APP.
