Stream Ciphers in ESP- IPsec Stack?
Hi all,
Is there any latest document/information regarding
use of
Stream ciphers like ARC-4 or RC4 in ESP of
IPsec/Firewall Stack?.
people seem to call ESP using Stream ciphers as
SC/ESP.
in that case, is there going to be change in
ESP packet format or packet processing ?
I happen to refer some internet drafts like
<draft-caronni-esp--stream-01.txt> and
<draft-mcgrew-ipsec-scesp-02.txt> second draft proposes no
change in ESP packet format but gives no idea about how to handle packets which
come out of order and how to provide Anti-Replay-Service, while former does give
implementation details of Antireplay service but there is a change in ESP packet
format as there is no pad length field present.
I'm looking for a complete document which addresses
all these implementation details, is there one?
Are there any products which have implemented
stream ciphers like ARC4 or RC4 in IPsec stack?
if so, can you give details there of ?
help in this regard is highly
appreciated.
thanks
Lokesh
