The main research content and innovation of the thesis include: 1. General encryption model of large data and the principle of encryption technology. Based on the systematic study of the basic characteristics of large data and the general encryption model, this paper deeply analyzes the technical principle and advantages and disadvantages of the four kinds of large data encryption schemes based on modern cryptography, bioengineering, attribute based and parallel computing.

2. A large data redundancy algorithm based on Bloom filter technique is proposed. According to the basic features of large data information, fast growth of data, variety of data types, low density and high redundancy, the performance of matching precision, time cost and space cost for 4 kinds of redundancy schemes such as complete file, fixed length block, variable length block and sliding window are deeply studied.

3. A large data encryption algorithm based on data redundancy technology is proposed. On the basis of eliminating redundancy of large data and combining the features of elliptic curve encryption algorithm and AES block cipher working mode in computational speed, parallelism and security, a large data encryption algorithm based on data redundancy technology is proposed.
