Multiprocessor and Many-Core Protections

Abstract

The prior chapters of the book, like most secure processor architectures, have focused on uniprocessor designs where there is only one processor. This chapter meanwhile discusses security issues in the design of secure processor architectures for computer systems which have more than one processor chip, or systems which have many processor cores on one chip. It first focuses on shared memory multiprocessors and distributed shared memory systems. It then covers security issues in many-core processor designs. The chapter ends with list of assumptions for multiprocessor and many-core secure architectures.
