Design of Security Gateway Based on Chaotic Encryption

In order to solve security issues in wireless sensor networks, a new security gateway based on chaotic sequences is proposed. Also introduced the application system architecture and implementation Program, provides a block diagram of system components. Using Logistic mapping, generates an infinite binary sequence to encrypt the data information to achieve a real sense of "one-time pad." Experimental results show that the algorithm achieved the goal to hide the data, and the algorithm has good robustness. Designed security gateway, WSN communications security problem has been resolved. Practice shows that the system has good generalization and application.
