PowMail : want to fork? : do some work

We design and implement PowMail, a secure email framework that uses proof-of-work to prevent impersonation attacks. PowMail uses a novel authenticated data structure called a Po W-tree to enable email users to jointly certify the history of all users' public keys. An implementation is given in the Go programming language. We evaluate PowMail and demonstrate its feasibility for securing email communications today.
