An improved key establishment scheme for wireless sensor network
Jaesung Yoo, Yoonho Lee, Dongho Won · 2011
In the wireless sensor network, traditional key management scheme such as public key cryptography is not suitable due to the limitations in terms of computational power, energy supply, and network bandwidth. In order to balance the security and efficiency, we propose a secure and low cost key establishment scheme. Our scheme selects exchanging data randomly and most data is not fixed. Therefore, it would force an adversary to conduct traffic analysis and maintains lower communication cost.
