Abstract

The invention discloses a short message secret communication method and system based on a chaos algorithm. The short message secret communication method comprises the steps that A, a sending terminal firstly performs scrambling encryption on data of a short message, and then performs an exclusive-or operation with a chaos sequence generated by a chaos system; and B, a receiving terminal firstly performs an exclusive-or operation on the data of the short message and the chaos sequence generated by the chaos system, and then executes anti-scrambling decryption. Encryption processing is performed on the short message according to combination of a short message protocol and the chaos system so as to realize secret communication of the short message. Meanwhile, an excellent encryption effect of the short message is ensured by combining inherent randomness, irregular orderliness and sensitivity for an initial value of the chaos system.

Description

technical field [0001] The invention relates to the field of communication security, in particular to a short message secret communication method and system based on a chaotic algorithm. Background technique [0002] With the development of mobile Internet and social economy, mobile terminals are becoming more and more popular. People can use mobile terminals to conduct various interactions and exchanges, which have become an indispensable tool in people's daily work and life. Especially in daily work and life, short messages are the simplest, fastest and most effective way of communication. However, with the rapid development of data communication, cases of illegal interception of short messages occur from time to time. How to ensure the safe communication of private short messages , is an important question. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the deficiencies in the prior art above, ...
