A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Cryptographic Proofs for HTTP Messages Author : Manu Sporny Filename : draft-sporny-http-proofs-00.txt Pages : 9 Date : 2014-08-26 Abstract: For a client to access a particular resource on the Web, a server must expend a certain amount of computational effort to respond to the request. In some cases this computational effort is sizeable and the server may want to only respond to certain clients. For example, in a distributed denial-of-service attack, a server may require all clients to expend a certain amount of resources via a client-run proof-of-work algorithm to throttle the number of incoming requests to a more manageable number. This document details a few HTTP Headers that may be used to request and transmit cryptographic mathematical proofs in HTTP headers.
