| 總結: | One of the most promising applications of low-earth orbit satellite systems is remote monitoring and control systems for unattended objects located in the Far North. Therewith, there is a tendency to increase the groupings of such satellites. Therefore, ensuring the information secrecy of the low-earth orbit satellite becomes an important task. To prevent the intruder satellite from imposing a previously captured and delayed control command, it is proposed to use the "friend-foe" system for satellites, which uses a zero-knowledge authentication algorithm. It is necessary to increase the speed of the satellite authentication process to reduce the probability of a response signal being picked up. To do this, it is proposed to use modular codes (MC), which can simultaneously perform the operations of addition, subtraction, and multiplication. As a result, the probability of picking up the signal of the responder located onboard the satellite is reduced. In addition, the MC can correct multi-bit errors within a single remainder in the presence of two redundant bases. Therefore, the development of an algorithm for correcting errors arising in the process of satellite authentication caused by failures, and interference in the communication channel is an urgent task. The work aims to increase the information secrecy of the low-earth orbit satellite by using the developed authentication algorithm, which has a minimum time for determining the satellite status, as well as an algorithm for correcting errors that occur during the operation of the satellite identification system and data transmission, implemented using a single algebraic system – parallel modular codes. |
