In this paper, we have proposed a lightweight blockchain based model to provide distributed authentication and anonymous authorization in IoD. We have proposed four different approaches to hide the identity of unmanned aerial vehicles UAV during the message exchanges using the blockchain. Non Interactive Zero Knowledge Proof (NIZKP) with bilinear map has been used to provide anonymity of UAV on the blockchain. The first approach describes a mechanism for the unlinkability of user identities. The second approach provides resistance against malleability attack together with unlinkability. The third approach ensures sender trackability to the receiver. In the fourth scheme, a UAV can delegate its task of tracking transactions to GCS in such a way that GCS can track the transaction of UAV but cannot claim the transaction’s authority. Relevant proofs of security for Signature Unforgeability and Unlinkability in Ciphertext (UN-C) are given to prove the strength of the techniques.

SpyChain:IoD中用于身份验证和匿名授权的轻量级区块链

在本文中,我们提出了一种基于轻量级区块链的模型,以在IoD中提供分布式身份验证和匿名授权。我们提出了四种不同的方法,以在使用区块链进行消息交换期间隐藏无人机无人机的身份。具有双线性映射的非交互式零知识证明(NIZKP)已用于在区块链上提供无人机的匿名性。第一种方法描述了一种用于用户身份不可链接的机制。第二种方法提供了对可延展性攻击的抵抗力以及不可链接性。第三种方法可确保发送者到接收者的可跟踪性。在第四种方案中,无人机可以将其跟踪交易的任务委托给GCS以这样的方式,GCS可以跟踪无人机的交易,但不能要求交易的授权。给出了密文签名不可伪造性和不可链接性(UN-C)的安全性相关证明,以证明该技术的优势。
