Analysis and Enhancement of Two Key Agreement Protocols for Wireless Networks
Anshul Singhal, Vaibhav Garg, Anish Mathuria · 2007
We analyze two recent key agreement protocols designed to provide access control in wireless networks. Both protocols are intended to be resistant to denial-of-service attacks. We identify computation DoS attacks against the protocols and model one of the attacks using a cost-based framework proposed by Meadows. We also identify several other security flaws in the protocols. We propose modifications to the protocols to improve their DoS resistance and overall security.
