Robust E-mail protocols with perfect forward secrecy
Bum Han Kim, Jae Hyung Koo, Dong Hoon Lee · IEEE Communications Letters · 2006
Recently, Sun et al., proposed a practical E-mail protocol providing perfect forward secrecy, but Dent showed that their protocol does not actually provide perfect forward secrecy. In this letter, we propose two new robust E-mail protocols, which indeed guarantee perfect forward secrecy.
