“…Even if short signatures where used (e.g., 200 bits) and the average end-to-end autonomous system hop count of 5 [46] existed within the overlay, every e-mail packet would end up with an additional 200 byte overhead, by the time it reached its destination.…”

Despite 30 years of on-going effort, spam remains a significant problem. While technology has abated the deluge of spam invading the average user's email inbox, spam still facilitates the sale of counterfeited products, distribution of malware, and other criminal activities -as well as the more insidious use of spear phishing to leverage attacks into corporate and government networks. The value of email arises directly from its anyone-to-anyone message-passing capability. Hence, anti-spam techniques based on end-point encryption have met with limited success. Furthermore, due to geopolitical concerns, most traceback techniques only work effectively within -and not across -geopolitical boundaries; and while targeted removal of spam-friendly ISPs and botnets has had significant impacts on spam rates, these gains have tended to be short lived.This work proposes a novel approach to control spam and spear phishing through combining peer-level quality-of-service (QoS) agreements with a ProVerif verified, non-repudiable traceback protocol to enact spam resistant overlays that are: i) scalable, ii) enforceable over geopolitical boundaries, and iii) do not require technological sea changes. Simulation results on an Internet-style network of 3,000 ISPs show that even in the presence of aggressive spammers, it is possible to reduce the spam versus normal email equilibrium from 90:10 to 20:80. Furthermore, this approach can be used to aid in controlling spear phishing attacks targeting federated organizations.

“…Given that the Autonomous System (AS) Number is 32 bits long, this would add 32 + 119 = 151 bits to the packet per hop. With a common AS path length of about 5 [25], this yields 246 + (5 * 119) = 841 bits, or 106 bytes. The destination mail servers have to store these packets for a certain period of time, to be able to facilitate a complaint under the peer-to-peer protocol.…”

Reducing email spam has been an active industry and academic research domain for a number of years. Despite this, spam has remained an on-going world-wide problem which absorbs significant network resources in its delivery. Client-side solutions have addressed much of the end-user nuisance factor, but trace-back solutions have not succeeded in sufficiently reducing spam ingress at its source due to both the movement towards distributed spam generation and geopolitical factors. At a systems-level, part of the inherent issue in addressing global spam is the current divergence between responsibility and accountability; end-users' are made responsible for addressing issues which the originating ISP's are better positioned to solve. Within this work, an overlay network-based approach is developed, which employs peer-to-peer QoS agreements in conjunction with a non-repudiation protocol for broadcast environments, to affect a low-spam overlay network. This of course does not solve the global spam issue, but does allow participating communities to move to a low-spam environment provided they are willing to accept their agreed to responsibilities.
