Title
A Secure and Energy-Efficient Key Generation Mechanism for Wireless Sensor Networks
Abstract
Abstract-Energy-efficient secure communication is important in wireless sensor networks (WSN) especially with applications that carry sensitive information. One solution to improve ,data confidentiality in WSNs uses a pre-installed shared key and hidden operation along with exposed key generators to frequently generate new keys that encrypt/decrypt messages. In this paper, weenhance,the data confidentiality and energy saving of the existing solution. Our mechanism utilizes encrypted message as a key generator for the next message. Thus a key ,generator (KG) that used to be ,exposed is now encrypted. A masking policy is incorporated to the encryption technique in literature that further improves the data confidentiality. Furthermore, the proposed method no longer requires a transmission of extra information in aform,of KGs reducing energy consumption incurred by data transmission. Analysis shows that ,the ,proposed ,method significantly increase encryption strength while reducing data transmission rate in the lowest tier of the network to 50% of the existing approach inliterature.
