Norrathep Rattanavipanon has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Augmenting executables having cryptographic primitives
    Patent number: 11934538
    Abstract: In general, this disclosure describes techniques for replacing target cryptographic primitives in executable binary files with other, potentially more secure, cryptographic primitives. In some examples, a computing system for augmenting cryptographic executables includes a locator to determine if an executable program in an executable binary file includes a target cryptographic primitive. The computing system can include a patch generator to generate patch instructions in response to a determination by the locator that the executable program includes the target cryptographic primitive. The patch instructions cause the executable program to execute a replacement cryptographic primitive instead of the target cryptographic primitive. A rewriter engine of the computing system can modify, based on the patch instructions, the executable program to generate a modified executable binary file.
