摘　　要：针对云系统中现有安全数据传输机制缺乏明确的数据分类以及传输过程中安全风险较大等问题,提出一种云系统中基于同态哈希认证的大数据安全传输。将不同类型的文件转换为文本文件,基于风险影响程度对其分类,文件被标识为机密或公共。当机密文件传输时,发送方加密文件,接收方基于同态哈希对发送方进行身份认证,确保数据安全性。在Hadoop分布式文件系统中,对所提方法的性能进行论证,实验结果表明,所提方法能够在提高数据传输安全性的同时尽可能小地影响数据传输量。In view of the lack of clear data classification in the existing secure data transmission mechanism in cloud system and the high security risk in the process of transmission,a secure transmission of big data based on homomorphic hash authentication in cloud system was proposed.Different types of files were converted into text files,which were classified based on the degree of risk impact.The files were identified as confidential or public.When the confidential file was transferred,the sender encrypted the file and the receiver authenticated the sender based on the homomorphic hash to ensure the data security.In the Hadoop distributed file system,the performance of the proposed method was demonstrated.Experimental results show that the proposed method can improve the security of data transmission while affect the data transmission as little as possible.
