CLASSIFICATION AND MITIGATION OF COMPUTE EXPRESS LINK SECURITY THREATS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17811770 titled 'CLASSIFICATION AND MITIGATION OF COMPUTE EXPRESS LINK SECURITY THREATS

Simplified Explanation

The patent application describes a system that enhances the security of a computing environment using compute express link (CXL) interface components. Here are the key points:

  • The system includes servers that create virtual machines for computing.
  • CXL interface components are used to communicate with the servers through CXL interconnects.
  • A controller is configured to perform various security measures:
 * Encrypt protocol data to protect against security threats related to CXL interconnects or malicious extensions.
 * Verify the identity of the CXL interface components through a secure handshake process.
 * Establish a chain of trust rooted in the hardware of the CXL interface components.
 * Restrict access to a specific memory area that stores security data for verified or secured processes.
 * Conduct security checks and configure security features of the CXL interface components.

Potential applications of this technology:

  • Cloud computing platforms that require secure communication between servers and virtual machines.
  • Data centers that need to protect against security threats associated with CXL interconnects or malicious extensions.
  • High-performance computing environments that require secure and trusted communication channels.

Problems solved by this technology:

  • Mitigates security risks associated with CXL interposer security threats or malicious extensions.
  • Ensures the authenticity and integrity of the CXL interface components.
  • Protects sensitive security data stored in the memory of the CXL interface components.
  • Establishes a secure and trusted computing environment.

Benefits of this technology:

  • Enhanced security measures for computing environments using CXL interface components.
  • Protection against potential security threats and unauthorized access.
  • Secure communication channels between servers and virtual machines.
  • Assurance of the authenticity and integrity of the CXL interface components.
  • Ability to establish a chain of trust rooted in the hardware of the CXL interface components.


Original Abstract Submitted

In some implementations, a system includes a set of servers configured to establish a set of virtual machines to provide a computing environment; a set of compute express link (CXL) interface components configured to communicate with the set of servers via a set of CXL interconnects; and a controller configured to at least one of: encrypt protocol data against a CXL interposer security threat associated with the set of CXL interconnects or a malicious extension security threat, provide a secure handshake verification of an identity of the set of CXL interface components, enforce a chain of trust rooted in hardware of the set of CXL interface components; restrict access to an area of memory of the set of CXL interface components that stores security data for verified or secured processes; or perform a security check and set up a set of security features of the set of CXL interface components.
