Past few decades witnessed the birth and explosive growth of the internet and the communications &ndash / most notably the electronic mail- through it. Studies indicate that although security measures are deployed, their usage is very limited and problematic. This work proposes a system to address some of the shortcomings of present mail security systems, such as underutilization, complicated key management and unwanted immunization against filtering-scanning. A two-layer message encryption scheme with domain level keys is introduced and a performance analysis is presented. An analysis of the improvement on the key management is also presented. Results show that, e-mails can be secured without significant performance impact, and visible ease of key management, by using the system proposed in this thesis.
