  • Lightweight code integrity solution with byte-pattern entanglement in program code
    Patent number: 12493541
    Abstract: A system and a method are disclosed for providing a lightweight code integrity solution. The system identifies one or more target code blocks in program code and determines one or more locations in the program code where an integrity check is to be embedded to verify the integrity of the code block. The system may determine an integer value associated with a byte-pattern of machine-code instructions in the code blocks and generates the integrity check by entangling the integer value into one or more computations of the program code. The system embeds the integrity check at the determined location in the program code.

  • Method and system for persisting untrusted files
    Patent number: 10885193
    Abstract: Securely performing file operations. A method includes determining a trust characteristic assigned to a file. When the trust characteristic assigned to the file meets or exceeds a predetermined trust condition, then the method includes performing a file operation on the file in a host operating system while preventing the file operation from being performed in the container operating system. When the trust characteristic assigned to the file does not meet or exceed the predetermined trust condition, then the method includes performing the file operation on the file in the container operating system while preventing the file operation from being performed directly in the host operating system.
