| 摘 要： | 以经典单向函数为基础,设计并验证了一种用于垃圾语音(Spam over Internet Telephony,SPIT)防范的方法.该方法利用资源挑战机制,要求垃圾语音的发送者消耗大量系统资源来破解谜题才可以发送语言会话请求.谜题设计算法避免了相关研究存在的缺陷,使得方法更加安全、可靠;谜题破解算法要求发送者对CPU与Memory进行双重消耗,从而缩小不同配置终端在破解过程中的消耗差距.对方法进行仿真实验,分析结果表明方法具有很好的有效性与适用性. |
| 关 键 词： | SPIT 单向函数 资源消耗 谜题设计 谜题破解 |

| Abstract: | Using classic One-Way Function as the basis,a SPIT prevention method is proposed and verified in this paper.Adopting the resource challenge mechanism,spitter is forced to consume huge system resource to solve the puzzle in order to send the session invite.The puzzle design algorithm avoids deficiencies of relevant research,makes the method more security and reliable.The puzzle solving algorithm consumes both the CPU and Memory of spitter,then reduces the consumption gap of puzzle solving during terminals with different configuration.Experiment and analysis show the efficiency and applicability of the method. |
| Keywords: | SPIT one-way function resource consumption puzzle design puzzle solving |
