摘　　要：针对WSN数据聚集安全算法通信与计算成本较高的问题,提出一种基于同态加密与改进椭圆曲线密码学的WSN安全数据聚集算法。首先,采用有态公钥加密算法降低加密算法的计算与通信成本,并且分别使用同态加密与消息认证码聚集密文与签名;然后,基站可提取每个节点的数据,验证消息的完整性、发送者的合法性以及识别恶意节点;最终,基于TelosB平台进行实验,并且使用快速算法实现椭圆曲线标量乘法降低该方法的执行时间。实验结果表明,该方法在保证数据安全性的前提下,计算成本与通信成本均明显低于其他同类型算法。To solve the high communication and computation overheads of the data security aggregation algorithm of WSN, a homomorphic encryption and improved elliptic curve cryptography（ECC） based security aggregation algorithm of WSN is pro- posed. The statefnl public key eucryption algorithm is used to reduce the communication and computation overheads, and the ho- momorphic encryption and message authentication code are used to aggregate the ciphertext and signature respectively. The base station extracts the data of each node to verify the integrity of all messages and validity of the senders, and identify the mali- cious nodes. The experiment is performed based on TelosB platform. The fast algorithm is used to realize the elliptic curve scalar multiplication to reduce the execution time of this algorithm. The experimental results show that the computation and communica- tion overheads of the proposed algorithm are lower than those of other similar algorithms on the premise of ensuring the complete data security.
