Robust Security Network (RSN) Fast BSS Transition (FT)
The 802.11 standard describes the generic process for 802. 1XEAP authentication and key management processes, which includes both generation and distribution of Master Session, Pairwise Master (and Transient), and Group Master (and Temporal) keys. This whitepaper describes specific features found in the 802.11 standard that are designed to aid wireless client stations in fast BSS transition (FT). Applications such as wireless Voice over Wi-Fi (VoWiFi) are being deployed at a surprising rate and interoperable FT mechanisms should be deployed b all vendors as a benefit to end users. Most vendors, with notable exceptions, now support Opportunistic Key Caching (also called Proactive Key Caching or Opportunistic PMK Caching).
