Introduction

I shall suppose, therefore, that there is, not a true Network, which is the sovereign source of trust, but some Evil Daemon, no less cunning and deceiving than powerful, which has deployed all of its protocol knowledge to deceive me. I will suppose that the switches, the admins, the users, headers, commands, responses and all friendly networked communications that we receive, are only illusory identities which it uses to take me in. I will consider myself as having no source addresses, obfuscated protocols, trusted third parties, operational client code, nor established state, but as believing wrongly that I have all such credentials.
