Security card, security card slot and board card

Abstract

The invention discloses a security card, a security card slot and a board card. The security card comprises a PCIE (peripheral component interface express) card, a TPM (trusted platform module) security chip and golden fingers, wherein the PCIE card and the TPM security chip are integrated together; the golden fingers comprise first golden fingers of the PCIE card and second golden fingers of the TPM security chip; an LCP signal of the TPM security chip is transmitted and connected to a south bridge through the second golden fingers; the first golden fingers and the second golden fingers are arranged side by side. According to the security card, the TPM security chip is arranged on the PCIE card, the LCP signal is connected to the south bridge through the second golden fingers, the TPM function is realized under the condition that the functions of the PCIE card are not affected, a client selects the standard PCIE card when the TPM security chip is not required and selects the PCIE card integrated with the TPM security card when the TPM security chip is required, and use convenience and security of the TPM security chip are realized.

Description

technical field [0001] The invention relates to the technical field of server board design, in particular to a safety card, a safety card slot and a board. Background technique [0002] At present, the PCIE (PCI-Express, bus and interface standard) card slot is widely used in servers because of its advantages of being easy to use and capable of expanding a variety of different devices. With different security requirements, different customers have different opinions on whether to use TPM (Trusted Platform Module, security chip). [0003] In the current design, the TPM is mainly designed to be integrated on the main board or connected to an external TPM card with a connector. The former method integrates the TPM security chip on the main board. When the customer does not need the TPM, the cost is higher. The latter method connects the TPM security chip to the external TPM card with a connector, although the cost is reduced, but when the external TPM card needs a connecting l...
