Chaotic encryption algorithm is simple, fast speed, no more memory, and suitable for using in wireless sensor networks (WSNs). This paper points out the defect of the iteration encryption and the fact that it’s vulnerable to chosen-plaintext attack. In this paper, a feedback chaotic encryption algorithm is proposed to improve the program that not only effectively avoid the defects, but maintain all the advantages of chaotic encryption algorithm. The improved algorithm is more suitable for small data encryption used in WSNs.
