Robust re-authentication and key exchange protocol for IEEE 802.11 wireless LANs
A. Ganz, Se Hyun Park, Zvi Ganz · 2002
We introduce a robust re-authentication and key exchange protocol for IEEE 802.11 wireless LANs. Based on an authentication protocol that we have previously published, we introduce a low computational complexity re-authentication and key exchange procedure that provides enhanced robustness in face of cryptographic attacks. This procedure accounts for the wireless media limitations, e.g., limited bandwidth and noise. We introduce the re-authentication period (RP) that reflects the frequency that the re-authentication procedure should be executed. We provide the user with suitable guidelines that will help in the determination of the re-authentication period.
