RFC 1948:
Title: Defending Against Sequence Number Attacks

Mailbox: smb@research.att.com
Pages: 6
Characters: 13,074

IP spoofing attacks based on sequence number spoofing have become a
serious threat on the Internet (CERT Advisory CA-95:01). While
ubiquitous crypgraphic authentication is the right answer, we propose
a simple modification to TCP implementations that should be a very
substantial block to the current wave of attacks.
