A New Certified Email Protocol
Hao Henry Wang, Yuyi Ou, Jie Ling, Xiang Hua Xu, Heqing Guo · 2007
As a continuative effort of our WICS'05 paper, a new certified Email protocol is proposed. Email is a standard communication method nowadays but certified email is poorly developed and has very limited application. A certified email protocol assures non-repudiability which means that if the email is successfully sent, the sender cannot deny s/he has actually sent the mail and the recipient cannot deny s/he has actually received it. Our protocol uses an efficient RSA-based convertible signature with noninteractive partial signature proof method and additively split signing secret key.
