with high rates of packets (>1Gpps) we seem to need about 37 bit (~5bytes).include a timestamp / sequence number to uniquely identify packets of the.The following goals/constraints led to this design:
#PACKET SENDER SAFE MAC#
The MAC input, as discussed above, so that also in this case no length It is visible from the metadata whether the addresses are to be skipped from The length of the addressįields is included in the first block of the AES-CBC MAC. This scheme is safe from length extension attacks on the AES-CBC MAC exceptįor the addresses, all fields are of a fixed size. Observe that when used with suitable a SPI referring to a DRKey, the address header may be left empty, resulting in an ideal If bothĪddresses are skipped, the row for the Address Type/Length fields byte is

Timestamp field to provide a unique identifier for a packet. When used with DRKey, this field is used together with the This use case is not specified in detail here. Is based on sliding window of expected counter values. Security association, this is used as a wrapping counter and replay detection When used with a SPI referring to an established This field can be used for replay detection by the receiver. The receiver SHOULD drop packets with timestamps outside of a locally chosen The Timestamp field can be used for replay detection by the receiver.
