Abstract

Compared with traditional wireless sensor networks, mobile crowdsensing networks have advantages of low cost, easy maintenance, and high scalability, which will play a role in city-level data sensing scenarios in the future. So far, linear homomorphic signatures based on Public Key Instruction,identity, as well as certificateless, have been proposed in wireless sensor networks to resist the data contamination. However, these signature schemes cannot perform finer-grained signature verification, and these signature schemes do not realize the separation of users’ sensitive information from their data. To solve the above problems, we design an attribute-based linear homomorphic signature scheme for large-scale wireless network built with mobile smart devices. First, we give the definition of the attribute-based linear homomorphic signature scheme based on key policy (KP-ABLHS). Second, we construct KP-ABLHS by incorporating attribute-based signature and linear homomorphic coding signature scheme. Finally, we prove our protocol is secure in random oracle model (ROM) and use Python pairing-based cryptography library (pypbc) to implement the scheme. The experimental results show that our scheme is as efficient as Li et al.’s scheme and has the advantage of signing the set of attributes, while the efficiency of our scheme is significantly better than that of scheme Boneh et al.’s scheme.

基于密钥策略的属性线性同态签名方案,适用于移动人群感应
与传统的无线传感器网络相比,移动群感网络具有成本低、易维护、可扩展性强等优点,未来将在城市级数据感知场景中发挥作用。迄今为止,在无线传感器网络中已经提出了基于公钥指令、身份以及无证书的线性同态签名,以抵御数据污染。然而,这些签名方案无法进行更细粒度的签名验证,而且这些签名方案无法实现用户敏感信息与数据的分离。为了解决上述问题,我们设计了一种基于属性的线性同态签名方案,适用于由移动智能设备构建的大规模无线网络。首先,我们给出了基于密钥策略的属性线性同态签名方案(KP-ABLHS)的定义。其次,我们结合基于属性的签名和线性同态编码签名方案构建了 KP-ABLHS。最后,我们证明了我们的协议在随机甲骨文模型(ROM)中是安全的,并使用基于配对的 Python 密码学库(pypbc)实现了该方案。实验结果表明,我们的方案与 Li 等人的方案一样高效,并且具有签署属性集的优势,同时我们方案的效率明显优于 Boneh 等人的方案。
