由于国际互联网黑客、木马、病毒的威胁,涉密网络为保证秘密信息不外泄,往往采用物理隔离的方式,虽然提高了安全性,但也给信息交换造成了不便。提出了一种基于多通道条码编解码技术的单向传输方案,采用光作为信息传输载体进行文件传输,保证了传输的单向性,传输速率可平稳在10KB/S,并且具有组建成本低、操作简单的特点,具有较高的安全性和实用价值。
Due to the threats of Internet hackers, Trojans and viruses, classified networks often use physical isolation to ensure that confidential information is not compromised. Although the security is improved, it also causes inconvenience to information exchange. A unidirectional transmission scheme based on multi-channel barcode encoding and decoding technology is proposed, which uses light as the information transmission carrier for file transmission, ensures unidirectional transmission and the transmission rate can be smoothly maintained at 10 KB / s, and has the advantages of low formation cost, Simple operation, high safety and practical value.
