Ccmp replay
AES-CCMP TSC replay was indicated on a frame( a frame with the same TSC(Sequence number). A replay of the AES-CCMP TSC in a received packet almost indicates an active attack. To understand and proceed further, where do you see this error message?. WebWPA Key Management. WPA and WPA2 (both Personal and Enterprise) utilize a key management mechanism called the Temporal Key Integrity Protocol, or TKIP. TKIP provides the dynamic key management that addressed the key reuse problems in WEP. TKIP is primarily used for WPA-Personal now, since it is based on the RC4 cipher, rather …
