In order to solve the problem of insufficient big data security,an improved big data encryption method based on field programmable gate array is proposed,which integrates chain oscillation ring,trigger array and XOR gate array.Then the method is verified by comparing with L8M-LBE and R2S-LBE.The experimental results show that the NIST test pass rate of the improved encryption method is 97.5%,which is better than the traditional true random number generator.In terms of en-cryption hardware throughput test,the throughput of the improved encryption method is 1983.3 Mbps,which is better than L8M-LBE and R2S-LBE.The experimental results show that the encryption performance of the improved true random number generator has been greatly improved,which can provide a new idea for big data encryption security.
