AI Technical Summary
Existing memory safety protection mechanisms are prone to failure when faced with complex attack code and methods, and cannot effectively prevent memory safety violations, especially in ROP attacks, where attackers can destroy code pointers and execute malicious attack code.
The marked memory scheme is adopted, which divides the memory space into safe memory spaces and assigns a memory mark to each memory subspace. The memory mark is used for fine-grained protection, and memory access is controlled by custom instructions to ensure that the memory mark matches the access address before operation can be performed.
It improves the security of computer systems, prevents unauthorized memory access, enhances the ability to resist sophisticated attacks, and ensures the security and reliability of memory access.
