摘要 在研究现有数据安全传输方案的基础上,设计并实现了一种基于DSP和USB接口的数据安全传输方案。该方案设计研制硬件安全板卡,硬件采用高速DSP芯片实现协议控制和密码算法,采用USB和EMAC作为数据传输接口。数据交换软件设计私有安全可靠通信协议,执行DES、AES、RSA等标准安全加密算法,保证数据的物理隔离和安全传输。测试证明,安全数据交换系统能够实现数据的机密性、完整性、不可否认性,保证数据可靠传输,具有较高的传输速率。 On the study of present data secure transmission schemes,a DSP-and USB-interface based data secure transmission scheme is designed and implemented.The scheme designs and develops a hardware safety card.Its hardware adopts a high-speed DSP chip to realize protocol control and encryption algorithm,and adopts USB and EMAC as data transmission interface.The data exchange software designs a private,safe and reliable communication protocol that executes DES,AES,RSA and other standard security encryption algorithms to guarantee the physical isolation and safe transmission of data.Test proves that the secure data exchange system can fulfill data confidentiality,integrity and undeniability,guarantee data's reliable transmission and bear higher transmission speed.
