摘　　要：文章以非对称和对称加密算法为理论基础,将数字签名和文件加密技术应用到隔离网闸中,在高可信域中数据传输至低可信域的过程中对数据进行数字签名和加密。实验结果表明,与单纯的网络隔离技术相比,加入数字签名和加密算法能够有效保证数据的保密性和完整性。Digital signature and file encryption technology are applied to network isolation, based on the theory of asymmetric and symmetric encrypfion algorithm, digital signatures and encryption algorithm are used in the process of data transfer from high credible domain to the low credible domain. Experimental results show that compared with the ordinary network isolation technology, digital signature and encryption algorithm can effectively guarantee the confidentiality and integrity of data.
