Practical Security in E-Mail Applications

چکیده
This paper deals with practicability issues of encrypted e-mails. A quick survey on the status quo indicates that popular e-mail clients lack substantial practicability qualities, for example searching in encrypted e-mails. Other approaches such as De-Mail provide solutions, but offer transport encryption only. We present and discuss a number of improvements to the practicability of e-mail encryption. These enable efficient searching in encrypted e-mails as well as subject encryption and the use of cryptographic functions in calendar applications. We present a prototype, called CryptoBird, providing a proof of concept for the proposed core features. Keywords—Calendar, CryptoBird, E-Mail, Encryption, PGP, Practicability, Searching, S/MIME
