XcalOS Kernel
车载安全操作系统微内核

Xcalibyte provides state-of-the-art specialized products including secure, formally validated operating system kernels and Hypervisors, both of which are increasingly being used for modern security products thanks to the boundless expansion of the Internet of Everything.

Booming industries such as autonomous cars and robotics require highly secure, never-down operating systems. Only a formally validated operating system can meet such stringent security requirements.

Common Problems with Existing Operating Systems

  • Standard unvalidated operating system kernels often have security vulnerabilities that make them unreliable.
  • Most operating systems are typically written in C and are prone to serious memory related vulnerabilities.
  • OS implementations often lack complete specifications that need to be followed.

Why validation?

Validation is the formal, mathematical, machine-checkable proof of correct implementation of operations to ensure total adherence to the semantics of a design specification.

Aside from secure operation, a kernel based on a fully validated operating system design often includes classic properties such as confidentiality, integrity and availability.

A Capability-based Access Control model supports fine-grain control over access to specific resources by individual entities in the system. Such an access control model achieves strong security through the principle of least privilege (POLA). Such core design principles for highly secure systems are impossible with the current standard access control approach of mainstream systems represented by Linux or Windows.

OUR EXPERTISE

Advanced Hybrid Critical Operating Systems

Our operating system is based on the most widely used open source seL4 operating system microkernel and is fully validated.

Machine-checkable and Secure Operating System

Machine-checkable proof ensures the correct implementation of security as defined in the design specification and ensures the security of time-critical systems.

Fine-Grain Access Control

Security is vastly improved through fine-grain access control.

Compliance Support

In addition to the features inherited from seL4, we support compliance with MISRA, ASIL-D, CC EAL and performance tuning of RISC-V-related hardware.
