摘　　要：海量数据加密的过程中需要进行大量的计算操作,而算法的复杂性会增加数据处理的时间,降低数据加密的性能。为此,使用复合混沌序列对海量数据进行敏感特征提取,以提取到的敏感特征为依据,通过逐步进位加法器,基于区块链对数据进行三进制的简洁编码,将编码后的数据作为加密的基础数据,对数据进行分割,并建立数据加密模型,实现对海量数据的精准加密。实验结果表明,设计的算法对不同大小数据的加密时间均小于4 s,说明设计算法效率较高,具有较好的应用价值,可以对数据进行快速精准加密。In the process of encrypting massive amounts of data,a large number of computational ope\|rations are required,and the complexity of algorithms can increase data processing time and reduce the performance of data encryption.To this end,a composite chaotic sequence is used to extract sensitive features from massive data.Based on the extracted sensitive features,a progressive carry adder is used to perform a concise ternary encoding on the data based on blockchain.The encoded data is used as the encrypted basic data,which is then segmented and a data encryption model is established to achieve precise encryption of massive data.The experimental results show that the encryption time of the designed algorithm for data of different sizes is less than 4 seconds,indicating that the designed algorithm has high efficiency and good application value,and can quickly and accurately encrypt data.
