Abstract:With the development of network information and communication technology, information of the data communication network information security become informationization the important problems in the process of data communication. Faced with the threat of a large number of invasive procedures and data leaks, a strong and effective data encryption algorithms become research direction in the field of study. RSA data encryption algorithm as the current algorithms for security is the highest, and on the big data under the condition of chaotic dynamic data node arrangement, is also unable to effectively ensure the safety of data encryption. Chaotic parameters, the crypto logical rupture, spilling, serious algorithms such as sequence inverse row holes. In this paper, chaotic parameter modulation of RSA encryption algorithm research, using chaotic parameters processing units, feature sequence logic control unit and the chaotic FIE - RSA algorithm for the problem of the traditional RSA encryption algorithm targeted to solve. Through the simulation experiments show that the chaotic parameter modulation of RSA encryption algorithm is put forward in the study, a series of methods have encryption processing fast response speed, operation time is short, with encryption security degree is high, the characteristics of anti cracking performance.
