Secure and efficient key generation and agreement methods for wireless body area networks

摘要

Wireless Body Area Network (WBAN) applications are becoming popular today. To protect patients' private data during transportation, secure wireless communications are mandatory in WBANs. Encryptions and secret keys are the base of secure communications over insecure wireless environments. Given most wireless nodes in WBANs are resource-constrained, efficiency is an implicit requirement of the key generation methods for WBAN wireless communications. Finding secure and efficient key generation method for WBANs is the goal of this article. We propose a practical, pure software method in this article. The new method has been proved to be highly secure and efficient.
