What is CCKM used for?

Using Cisco Centralized Key Management (CCKM), an access point that is configured for wireless domain services (WDS) uses a fast rekeying technique that enables Cisco client devices to roam from one access point to another typically in under 150 milliseconds (ms).

What is CCKM authentication?

In a nutshell, CCKM is a variation on WPA designed to provide fast secure roaming in addition to Secure authentication and Encryption (via 802.1x and TKIP/MIC). CCKM works for LEAP only today, and provides layer 2 roaming including 802.1x authentication with sub-150ms Latency.

Is CCKM enabled by default?

CCKM function is supported on CK/CN series mobile computer. This function is disabled in default and it can be enabled through the following step. Procedure: Go to ‘Intermec Settings’ > ‘Communications’ > ‘802.11 Radio’ > ‘Funk Security’ > ‘Profile x’ .

What is OKC roam?

OKC is a fast roaming technique supported by Microsoft and some Android clients. Another fast roaming method is the use of 802.11r, which is supported by Apple and few Andorid clients. OKC is enabled by default on a WLAN. This configuration enables the control of OKC on a WLAN.

What is WPA2 policy?

WPA2 is a security protocol framework that is used to protect wireless networks. WPA2 is currently considered as the most secure method to protect a Wi-Fi network. It provides layer 2 based security and uses IEEE 802.1x port based authentication protocol.

When a WPA2 PSK WLAN is configured in the wireless LAN controller What is the minimum number of characters that is required in ascii format?

If an ASCII password is used to secure WPA-PSK the length must be between 8-63 characters.

What is PMK caching?

PMK caching allows the client to skip 802.1X authentication to any AP to which it has previously authenticated (only the 4-way handshake is required). PMK Caching is the method defined in the 802.11i specification, which also defined WPA2.

What is opportunistic cache?

Opportunistic Key Caching is a fast roaming feature built upon the PMK caching feature of 802.11 security. When a WLAN is configured for WPA2-Enterprise, client association on that WLAN takes part in three stages: 802.11 Authentication and Association messages are exchanged between the AP and the client.

What is WPA2 WPA3?

WPA3, also known as Wi-Fi Protected Access 3, is the third iteration of a security certification program developed by the Wi-Fi Alliance. WPA3 is the latest, updated implementation of WPA2, which has been in use since 2004. The Wi-Fi Alliance began to certify WPA3-approved products in 2018.

What is PMK in WiFi?

After the PSK or 802.1X authentication, a shared secret key is generated, called the Pairwise Master Key (PMK). In PSK authentication, the PMK is actually the PSK, which is typically derived from the WiFi password by putting it through a key derivation function that uses SHA-1 as the cryptographic hash function.

What is a Pmkid?

PMKID is a hashed value of another hashed value (PMK) with 2 MACs and a fixed string. PMKID = HMAC-SHA1-128(PMK, “PMK Name” + MAC (AP) + MAC(Supplicant)) HMAC-SHA1 is again just an example of a pseudo-random function. PMKID is a field in the RSN IE frame (Robust Security Network Information Element).
