Benefits of technology

This patented technology uses two different modules - one for both types of data processing: A key-value (KV) blockchain system or other secure storage mechanism called BCM). It achieves higher levels of safety by providing multiple keys separately encrypted into each component during manufacturing. Once these components have gone wrong they cannot be reused without compromising their integrity. By measuring the quality of software installed onto them after it's sent from production, any changes made can be detected even if there were no problematic issues later. Overall, this innovation improves servers' overall level of security while maintaining its effectiveness over older systems.

Problems solved by technology

The present patented methods aim at improving the reliability and safety of software applications running within computers or communications networks through implementing specialized hardware components called trust chains with specific rules set up between them. These techniques help ensure secure execution of code even if they are compromised during operation due to external factors like virus attacks or malfunctions.

Abstract

The embodiment of the invention discloses an establishing method and system of a trust chain. The method comprises the steps of starting a BMC module and a TCM module before a server is powered on; adopting the TCM module to scale BMC firmware in the BMC module to obtain a first scaling result, and judging whether or not the BMC firmware is tampered according to the first scaling result; if the BMC firmware is not tampered, adopting the BMC firmware to scale BIOS-Boot-Block to obtain a second scaling result, and judging whether or not the BIOS-Boot-Block is tampered according to the second scaling result; if the BIOS-Boot-Block is not tampered, controlling a power control module to power on the server, and adopting a BIOS to establish the subsequent trust chain. According to the establishing method and system of the trust chain, the safety of the trust chain is improved when the trust chain is established, and accordingly the safety of the system is improved.
