Abstract

The invention discloses a server and a security protection system for a JTAG interface of the server. The system comprises a processor, an external JTAG interface and a connection module, wherein theprocessor is fixedly connected with the JTAG interface of the server so to avoid connection between terminal equipment and the external JTAG interface through the connection module, the processor match the connection module to verify the terminal equipment, and a communication line between the JTAG interface of a server and the terminal equipment is switched on when the verification is passed, sothat the terminal equipment is prevented from being directly connected with the JTAG interface of the server.By means of the mode, only the terminal equipment passing verification can communicate withthe JTAG interface of the server, safety protection of the JTAG interface of the server is achieved, and the protection process is simple. Subsequent maintenance is easy.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to a server and a safety protection system for a JTAG interface of the server. Background technique [0002] The server security standard has the requirement that the hardware interface must pass the certification to connect. Among the currently commonly used Debug interfaces, the USB (Universal Serial Bus, Universal Serial Bus) interface has been designed very well, and there are various security protection methods; UART ( Universal Asynchronous Receiver / Transmitter (Universal Asynchronous Receiver / Transmitter) serial port also supports the access method of security authentication. But the JTAG (Joint Test Action Group, Joint Test Working Group) interface does not have a ready-to-use protocol or hardware modification to realize the security protection of the interface. At present, most servers only protect the JTAG interface at the purely physical level, such as physical...
