"Scanrand is a proof of concept, investigating stateless manipulation of the TCP Finite State Machine."

"It implements extremely fast and efficient port, host, and network trace scanning, and does so with two completely separate and disconnected processes -- one that sends queries, the other that receives responses and reconstructs the original message from the returned content. Security is maintained, in the sense that false results are difficult to forge, by embeddeding a cryptographic signature in the outgoing requests which must be detected in any received response. HMAC-SHA1, truncated to 32 bits, is used for this "Inverse SYN Cookie".
