摘　　要：针对分布式无线传感器网络数据传输易遭受攻击、安全性难以保证的问题,提出了一种基于MD5算法的数据安全传输方法。利用哈希函数可以方便快捷地生成一定格式的摘要,再根据摘要很难反推出原始信息的特点,在发送数据的末尾附上一段计算好的信息摘要,在接收端对数据重新生成一次摘要,通过与发送端的摘要进行对比,可以检验数据传输的安全性。通过仿真实验验证了其有效性。Considering the fact that distributed wireless sensor networks are easily attacked and difficult to guarantee their security,we have proposed a method of data secure transmission based on MD5 algorithm. As the original information is difficult to be revealed by an abstract of a certain format easily generated by hash function,a new abstract has been produced by attaching the abstract of calculated information to the receiving end. Then the security can be tested through the comparison of both abstracts. The simulation results show that this method is efficient and effective.
