针对大数据传输中的数据机密性、完整性和数据丢失等问题,提出一种基于简化数据加密标准(Sim-plified Data Encryption Standard,SDES)和双轮差错控制的大数据集成安全系统。使用SDES加密算法生成加密字符串,并设计意外数据丢失备份系统以提高机密性和防止意外数据丢失。基于双轮差错控制以较低的空间开销控制传输过程中包含的任意数量的离散或连续错误位,基于固定长度编码(Fixed Length Coding,FLC)的无损压缩技术来减少数据开销。该算法具有较高的AE值、熵和压缩百分比,具有提供更高的数据机密性和完整性的潜力。
BIG DATA INTEGRATED SECURITY SYSTEM BASED ON SDES AND DUAL ROUND ERROR CONTROL
To solve the problem of data confidentiality,integrity and data loss in big data transmission,a big data integrated security system based on simplified data encryption standard(SDES)and dual round error control is proposed.SDES encryption algorithm was used to generate encrypted string,and backup system for unexpected data loss was designed to improve confidentiality and prevent accidental data loss.Based on dual round error control,any number of discrete or continuous error bits contained in the transmission process was controlled with low space cost,and lossless compression technology based on fixed length coding(FLC)was used to reduce data overhead.The proposed algorithm has higher AE value,entropy and compression percentage,and has the potential to provide higher data confidentiality and integrity.
