2. Draft 7.0 Clause 8.3.2.3.4 TKIP Replay Detection:
doc.: IEEE /0132
January 2004
January 2004
Draft 7.0
Clause TKIP Replay Detection:
“Each TSC (48 bit counter) shall be selected from a single pool by each transmitter for each temporal key—i.e., each transmitter has its own unique TSC for each directional temporal key established.”
“A receiver shall maintain a separate set of TKIP TSC replay counters for each MAC address from which it has received TKIP traffic.”
Clause PN and Replay Detection (i.e. CCMP):
“The PN (a 48-bit counter) shall be selected from a single pool by each transmitter for each temporal key (TK).”
“A receiver shall maintain a separate set of PN replay counters for each MAC address from which it receives CCMP traffic.”
Based on this text, it is not clear that a receiver must support a separate replay counter(s) for multicast/broadcast traffic.
