Abstract

E-mail communication still has to cope with certain security problems. The most visible result is the mass of unsolicited messages outnumbering the regular e-mails in magnitudes. The technical reasons for this unfavourable situation are manifold e.g., unreliable sender authentication, Loose and ad-hoc coupling between the involved servers, and only few ways to complain about misbehaviour of users of foreign systems. To make e-mail communication secure and private, e-mail servers incorporate one or more security features using add-on security protocols. The add-on Security protocols provide a reasonable security. 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 propose bridge-type e-mail proxy architecture to release the bottlenecks of the two popular mail security architectures: software mail filter and e-mail gateway.
