分析了网络隔离技术的优劣,提出采用基于Gap技术框架的安全、高速的整体化隔离系统。在基于Gap技术的体系结构中,通过结合硬件基础、底层的安全通信协议和应用服务的一体化安全通信机制保证数据传输的安全性和高效性。在嵌入式LINUX系统的支持下,遵循SCSI接口标准,设计专有的安全通信协议,实现可实用化的隔离系统。实际测试表明隔离系统在安全性和高速数据传输方面具有良好的性能。 The advantages and disadvantages of network isolation technology are analyzed, and a secure and high-speed integrated isolation system based on Gap technology framework is proposed. In the architecture based on Gap technology, the security and high efficiency of data transmission are ensured by an integrated and secure communication mechanism combining hardware foundation, underlying safety communication protocol and application service. Under the support of embedded LINUX system, follow the SCSI interface standard, design a proprietary secure communication protocol, to achieve a practical isolation system. The actual tests show that the isolation system has good performance in terms of security and high-speed data transmission.
