Trusted platform module board card

Abstract

The invention discloses a trusted platform module board card, which comprises a complex programmable logic device, a software kernel for storing a trusted platform module, and a protection device foroperating the software kernel to realize a protection function of the trusted platform module, the external storage chip is connected to the complex programmable logic device and is used for storing temporary data after the complex programmable logic device is powered down; the crystal oscillator is connected to the complex programmable logic device and used for providing a clock source for the complex programmable logic device; and the field replaceable unit is connected to the complex programmable logic device and is used for storing asset information of the complex programmable logic device. According to the method, the logic topology can be simplified, the method is compatible with various usage scenarios, the flexibility and universality are improved. Meanwhile, the safety effect of obtaining the TPM information before starting is kept.

Description

technical field [0001] The invention relates to the field of server security, more specifically, to a trusted platform module board. Background technique [0002] In recent years, with the rapid development of Internet technology, cloud services and cloud computing have flourished. Information security is one of the current hot spots. Although network security technology enhancement technologies emerge in an endless stream, computer systems are always facing threats such as hacker attacks and virus intrusions, which seriously affect the normal operation of computer systems. The emergence of trusted computing, by adding TPM (Trusted Platform Module) on the computer motherboard, through the establishment and transmission of the chain of trust to ensure the information security of the computer system, solves the traditional software technology that is difficult to solve the security risks of the computer system structure , which opens up a new way to strengthen the security of...

Problems solved by technology

[0003] A kind of prior art needs TPM to have SPI (Serial Peripheral Interface) bus to be connected to BMC (baseboard management controller) in hardware aspect; Software aspect needs to realize the driver program of TPM in BMC Uboot (starter), and obtain TPM Function interface of information; this can realize the trusted boot of BMC, but the SPI bus and TPM driver increase the complexity of the scheme

In another kind of prior art, TPM does not have SPI bus to be connected to BMC, can only obtain the information of TPM by PCH (platform controller hub) after system startup, but BMC has no way to obtain TPM information before system startup like this, Not good for checking the status of the TPM card

[0004] There is currently no effective solution to the problems of complex topology and low security in the prior art
