Patents by Inventor John Hongjip KIM

John Hongjip KIM 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).

  • Electronic device and secure booting method thereof
    Patent number: 12346450
    Abstract: An electronic device loads a boot code and checks a select bit. When the select bit has a first value, the electronic device verifies the boot code based on a pre-quantum cryptography algorithm. If verification of the boot code fails, the electronic device verifies the boot code based on a post-quantum cryptography algorithm. If verification of the boot code based on the post-quantum cryptography algorithm is successful, the electronic device sets the select bit to a second value.
    Type: Grant

  • EGM authentication mechanism using multiple key pairs at the bios with PKI
    Patent number: 9141952
    Abstract: Executable applications on a gaming machine are verified before they can be executed, for security purposes and to comply with jurisdictional requirements. Unlike in prior systems for authenticating the executable applications, embodiments allow for new executable applications to be provided and verified over time with different private and public key pairs, even after the operating code of the gaming machine is certified by the jurisdiction and deployed in the field.
