Embodiment Construction

[0044] System overview:

[0045] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to obscure the present invention.

[0046] Reference is now made to Figure 3, which is a schematic block diagram of a credential-based computer system 40 in accordance with an embodiment of the present invention. System 40 may utilize cryptographically signed capability tokens, hereinafter referred to as credentials, to secure access to memory 50, as will be described in detail below.

[0047] In system 40, a user (not shown) in communication with memory 50 may request direct memory access (DMA) to memory 50 from one or more IO devices 14[1]-14[i]. In p...

Abstract

A computer-implemented system and method for protecting a memory are provided. The system includes a memory section with privileged and non-privileged sections, a host gateway (HG) to generate a capability credential, a device controller (DC) to append the credential to data transmitted to the memory, and at least one IO device enabled to do direct memory access (DMA) transactions with the memory.

Description

technical field [0001] The present invention relates generally to the field of computer and processor architectures. In particular, the present invention relates to methods and systems for memory protection and security using credentials. Background technique [0002] The architecture of the latest personal computer (PC) system from desktop to server can be conceptually and schematically described by FIG. 1 , now refer to FIG. 1 . [0003] PC system 10 generally includes memory 20, which may be embedded within one or more processing units 12, or may be separate therefrom. Processing unit 12 is typically coupled to IO devices 14[1]-14[i] via one or more IO buses 16, such as Peripheral Component Interconnect (PCI) buses. Some or all of the IO devices may be coupled to an IO bridge 17 , which may be coupled to the IO bus 16 . Optionally, to make the connection between processing unit 12 and IO devices 14[1]-14[i] faster, PC system 10 may also include a or multiple component...
