  • Error report normalization
    Patent number: 10430265
    Abstract: Error report reporting errors that occur during software execution may be normalized to account for diversification of single software program. A method for useful providing error reports comprises receiving information regarding computer system status at a time of failure of proper execution of a diversified implementation of a computer program, the computer program having a plurality of diversified implementations; and transforming the information regarding the computer system status using metadata indicative of differences between the diversified implementation of the computer program and a canonical implementation of the computer program.
    Type: Grant

  • Code randomization for just-in-time compilers
    Patent number: 9250937
    Abstract: A system-wide service can simultaneously harden multiple running JITs, for example by hooking into the memory protections of a target operating system and randomizing newly generated code on the fly when marked as executable. Some embodiments preserve the contents of the calling stack, presenting each JIT with the illusion that it is executing its own generated code.
