Description

Time tracing encryption time service card
Technical Field
The invention relates to the technical field of computer time service cards, in particular to a time tracing encryption time service card.
Background
The time service card is also called a time code card or a time synchronization card, and the main working principle is that high-precision time information provided by an external time source (such as GPS, beidou satellite, network time protocol NTP and the like) is received and then transmitted to a computer system, so that the time synchronization and the calibration of the computer system are realized.
The time service card typically includes a high precision time receiving module and an interface module for communicating with the computer system. The time receiving module is used for receiving and analyzing time signals sent by an external time source, converting the signals into a time format which can be identified by the computer system, and the interface module is used for transmitting the converted time information to the computer system and providing a timing interrupt signal for the computer system according to the requirement.
In a computer system, a time service card can be configured as a reference source of a system clock for calibrating the deviation of the system clock, and when the computer system needs to acquire the current time, the time service card can read time information from the time service card instead of relying on an internal clock, so that the time precision and stability of the computer system can be greatly improved, and particularly in the fields with very strict time requirements, such as financial transactions, communication networks, aerospace and the like.
The traditional PCIE time service card is a time service board card with high-precision time input and output, and has the functions of receiving GPS/Beidou, B (DC), 1588PTP, NTP, CDMA time and the like. And outputting high-precision time information, geographical position and other information through the PCIE bus. The time information output by the PCIE bus is time code information, the data is displayed as a plain code of time, month, day, time, second and millisecond, for a computing system, the acquired time information has no method for confirming whether the time information is from a time service card or the time of a local system, in addition, the possibility that the time data is falsified in the time data transmission process exists, and the current digital technology requires the time information as a data base element to have the requirements of safety and credibility, so the invention redesigns the time service card structure, and solves the problems of tracing the time of the time service card and encrypting and falsifying the time data.
The whole external view of the product is that the MINI-PCIE connector is added in the structure of the product on the basis of not damaging the appearance of the time service card, and the integration of the time service card and the time service card is realized by integrating the encryption card, so that the novel appearance of the encryption time service card is formed. The MINI-PCIE base is innovatively added on the time service card structure, and the USB2.0 protocol is adopted to interact in-phase, so that an adaptive MINI encryption card can be inserted.
The encryption of the time data is an effective means for protecting the safety of the time data, can improve the safety, the integrity and the credibility of the time data, and prevents the leakage, the tampering and the illegal acquisition of the time data, thereby being an important measure for guaranteeing the information safety.
