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.

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.

Abstract: An engine system may include an electric or mechanical supercharger and an LP-EGR, basically with a turbocharger, an EGR valve, a channel control valve, and a bypass valve, which control the flow rate of external air and exhaust gas, may be integrally operated, and a operation section may be divided into a turbo-lag and low torque section, a mid-load section, and mid/high-load section such that the open amount of EGR valve, channel control valve, and bypass valve may be optimally controlled, such that it may be possible to improve availability for a low-speed/high-load section with turbo-lag reduced, using supercharger and considerably increase the ratio of fuel efficiency improvement in the low-speed/high-load section, using LP-EGR operating with supercharger.
