Hi

I’ve submitted this draft for a method of mitigating DoS and DDoS attacks using client puzzles.  The puzzle in this draft is a partial break of SHA-256.

Comments are welcome.

> Abstract:
>   This document proposes a mechanism for mitigating denial of service
>   (DoS) and distributed denial of service (DDoS) attacks on TLS
>   servers.  Attackers are limited in their ability to cause resource
>   waste on the server by requiring proof of work by the client before
>   these CPU resources are expended.
