摘要:

传统无线传感器网络数据加密聚合方案在密文数据运算、抵御内/外部攻击、追查并修复错误等方面存在安全性和效率方面的不足。为此,提出一种全同态数据加密聚合方案。采用DGHV全同态算法对隐私数据进行加密,并将节点的身份信息嵌入到数字签名中,使方案具有追查并修复错误的能力。此外,该方案无需可信第三方,以簇为单位分配干扰因子,以抵御内部攻击并提高运行效率。实验结果表明,该方案是IND-CPA安全的,能抵御内/外部攻击且满足全同态性。

Abstract:

Traditional data encryption aggregation schemes in Wireless Sensor Network(WSN) have some shortcomings in security and efficiency,such as ciphertext data operation,resist internal/external attacks,tracking and repairing errors.To solve this problem,a fully homomorphic data encryption aggregation scheme is proposed.DGHV homomorphism algorithm is used to encrypt the privacy data,and the identity information of the node is embedded in the digital signature,so that the scheme has the ability to trace and repair errors.In addition,the scheme does not require a trusted third party,it allocates interference factors in clusters to defend against internal attacks and improve operational efficiency.Experimental results show that the scheme is IND-CPA secure,and it can resist internal/external attacks and satisfy the full homomorphism.

Key words: Wireless Sensor Network(WSN), fully homomorphic encryption, cluster, data aggregation, trusted third party
