摘　　要：针对无线传感网络安全问题日趋严重,无线网络中的通信信息经常泄漏的问题,本文提出了基于改进IBE的无线网络信息加密方案。该方案在传统IBE方案的基础上,引入基于中间公钥和门限的私钥分发协议,使用共享主密钥的方法保护主密钥的安全,使用中间公钥来验证密钥方的身份,通过随机对称密钥加密明文。经过安全性能分析表明,本文提出的改进方案安全性能得到了优化,并在提高其安全性能的前提下没有降低其加密和解密的速度,该方案切实有效。On consideration of increasing importance of the security in wireless sensor network,and of common leakage of communication information in wireless network,this paper put forwards a data encryption scheme based on improving IBM.The scheme,on the basis of traditional IBE scheme,introduces a distribution protocol on the middle public key and on private key of the threshold.It protects the primary key’s security by sharing the primary key,verifies the key holder’identity by middle public key and encrypts the clear data by random security key.The analysis on security performance indicates that the security performance in the improved scheme in this paper has been optimized and hasn’t deduced the encryption and decryption speed with improving the security performance.So the scheme is practical and effective.
