Abstract

A processing system includes a processing module having a first interface coupleable to an interconnect. The first interface includes a first cryptologic engine to encrypt a representation of store data of a store operation and a memory address using a first key and a first feedback-based cryptologic process to generate first encrypted data and an encrypted memory address. A memory module includes a second interface coupled to the interconnect. The second interface includes a second cryptologic engine to decrypt the first encrypted data and the encrypted memory address using a second key and a second feedback-based cryptologic process to generate a copy of the representation of the store data and a copy of the memory address. The second interface further is to store the copy of the representation of the store data to a memory location of the memory core based on the copy of the memory address.
