摘要
一个完整的数据加密系统应该具有安全可靠的密码认证机制和加密算法,为了解决现有大多数认证系统中逻辑认证的局限,利用两片FPGA芯片、PCI控制器、MEMS强链和AES算法设计了一种高效的数据加密系统,实现了物理认证和数据的加密/解密,利用AES-128加密算法对数据进行加解密,提高了安全等级。该系统具有简捷方便、性能稳定、数据吞吐率高等特点。
A complete data encryption system must have a reliable authentication mechanism and an advanced encryption algorithm. To handle the disadvantage of logic authentication in most of the data encryptions, a new fast encryption system based on two FPGA chips is introduced, PCI controller and MEMS stronglink, and its encryption algorithm is AES, with the AES-128 algorithm, the safelyrank ofthe system is improved greatly. The system can complete safety identification and encryption/decryption, and it has many advantages, such as simple and convenient, stable performance, large data throughput rate.
