Novel highly secure distributed e-mail system

摘要

Conventional e-mail systems are vulnerable to eavesdropping in the network due to the condition that each email path is established based on a point-to-point protocol. This means that some practical protocols to strengthen security should be introduced. From this viewpoint, we propose the utilization of multiple e-mail accounts and multiple Wi-Fi channels based on HS-DRT technology. This will enable high-speed encryption and a high level of security. Utilizing HS-DRT for e-mail communication makes it possible to automatically disperse and send the encrypted fragments over multiple different paths to the destination user. It makes it impossible for a third party to decipher the original e-mail message even if there are continuous attempts to eavesdrop the same message. In the performance evaluation, we compare the performance of the proposed mail system with that of a conventional system by examining it in a large number of multi-account environments. We also evaluate the processing time needed to encrypt each fragment and possible transmission time intervals.
