To effectively encrypt data memory contents of an embedded processor, multiple keys which are dynamically changed are necessary. However, the resources required to store and manage these keys on-chip (so that they are secure) can be extensive. This paper presents a design where each dynamic key is determined by a random number, a counter value, and a memory… CONTINUE READING
