Advanced dynamic encryption---a security enhancement protocol for IEEE 802.11 and hybrid wireless network.

摘要

Data integrity and privacy are the two most important security requirements in wireless communication. Most mechanisms rely on pre-share key data encryption to prevent unauthorized users from accessing confidential information. However, a fixed secret key is vulnerable to cracking by capturing sufficient packets or launching a dictionary attack.;In this research, a dynamic re-keying encryption protocol was developed to enhance the security protection for IEEE 802.11 and hybrid wireless network. This protocol automatically updates the secret key during the end-to-end transmission between wireless devices to protect the network and the communication privacy. In addition, security analyses are given to verify the protection of this protocol. Experiment results also validate that the dynamic encryption approach can perform as efficiently as other security architectures while providing an additional layer of data protection.
