云计算平台下一种新型反垃圾邮件系统的研究

A novel anti-spam system on cloud computing platform

针对现有SMTP(simple mail transfer protocol)中接收方被动接收信息的缺点,设计一种新型反垃圾邮件系统。该系统通过设计改进型DMTP(differentiated mail transfer protocol),减少不必要的网络流量;通过引入云计算机制,减小传统反垃圾邮件系统负荷,从而降低用户时间消耗。研究结果表明:与现有邮件系统相比,该系统的用户处理时间、网络流量、垃圾邮件发送方获益均降低。

A novel anti-spam system was proposed to overcome the disadvantages of SMTP （simple mail transfer protocol）. In this system, an improved DMTP （differentiated mail transfer protocol） was designed to reduce unwanted network traffic. Also, the cloud computing mechanism was introduced into this system to reduce computational burden and time cost. The results show that the proposed system outperforms the previous systems into terms of receiver time cost, network traffic and spammer revenue.
