PowMail : want to fork? : do some work

[摘要] 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.
