Problems solved by technology

However, as the core equipment in the simulation system, the security research of the general-purpose simulation computer has not received corresponding attention, resulting in many potential safety hazards: the user identity lacks an effective and reliable authentication mechanism, and the user can easily enter the simulation computer; Access to key data files and programs lacks effective authorization and can be accessed and modified by users at will; confidential information is not protected and is easy to be stolen and tampered with; data storage devices can be used illegally after being lost or stolen, etc.

Abstract

The invention discloses a trusted secure simulation computer, comprising a secure mainboard platform, a TPM secure chip, a secure BIOS, a secure hard disk and an I / O subsystem. The secure mainboard platform is composed of an Intel Core Duo processor and an Intel 9456 chip. The I / O subsystem comprises a high-speed digital to analog conversion D / A card, a high-speed analog to digital conversion A / D card and a digital input and output D / D card. The TPM secure chip communicates with the secure BIOS through a trust root. The secure hard disk communicates with the secure BIOS through trust chain transmission. According to the trusted secure simulation computer provided by the invention, a high-precision time counter is employed; a binary time stamp counter based on GPU main frequency exists in the Intel Core Duo processor; the nanosecond level control time is obtained through utilization of a product of the counter and the clock cycle of a CPU; and the relatively high guarantee for real-time synchronization control and communication of the simulation computer and an externally connected device is provided.

Description

technical field [0001] The invention relates to a simulation computer, in particular to a credible and safe simulation computer, which belongs to the technical field of computer equipment. Background technique [0002] Digital simulation computers are the basis and core of modern simulation systems, and play a huge role in real-time hardware-in-the-loop simulations of major missions such as missiles and rockets. At present, digital simulation computers mainly include two types, namely, special-purpose simulations based on multiprocessors Computer systems and general-purpose simulation computer systems based on high-end microcomputers and workstations; compared with special-purpose simulation computer systems, general-purpose simulation computer systems support rich hardware and software resources, are cheap, friendly, and easy to expand and use. With the rapid development of computer technology and microelectronics technology, the research, development and application of sim...
