Design and implementation of multipath security connection anti-replay attack based on FPGA

Abstract： Replay attack is a common network attack method. To improve the security of network devices, a design scheme of anti-replay attack based on FPGA is proposed. Combined with engineering practice, firstly the communication principle of security connection is introduced, then the implementation mechanism of anti-replay attack is discussed in detail. On this basis, an anti-replay design scheme for multipath security connection is proposed. The research results show that the technology can meet the requirements of multipath security connection communication and anti-replay attack. The implementation protocol of the method is simple and the data throughput rate is high, which can be used for reference in engineering implementation.
