Introduction

The Internet of Things (IoT) comprises of various smart devices for the sharing of sensed data through online services. People will be directly contacted to check their health parameters and the reports will be collected centrally through smart devices. The requirement is protection of messages during the exchange of data between sender and receiver in order to tackle human malicious attacks. Various signature-based schemes are discussed in the literature to provide secure communication. Smart devices however require lightweight tasks by ensuring critical safety strengths. An important problem in the signature based method is that it incurs more computational expenses for signing and verification process in large numbers.

Objectives

In this study, we introduced an efficient Short Signature Scheme (SSS) that uses Fractional Chaotic Map (FCM) for secure communication in IoT based smart devices, the security of which is closely related to a random oracle based on FCM assumption.

Methods

In this study, we have designed new short signature scheme using FCM. The presented scheme consist of four sub-algorithm as follows: setup, key generation, signing and verification. We have used less rigorous operations based on the FCM to carry out signing and verification procedures, similar to human signing on valid documents and then verifying them as per witness.

Results

The proposed SSS offers a better security assurance than currently established signature schemes. The key advantage of the SSS over the DSA schemes is that at the verification stage and signing period it takes less computation; it retains the degree of protection. The presented SSS takes less bandwidth for storage, communication, and computing resources; particularly applicable to wireless devices and smart cards.

Conclusion

We concluded that the uses of fractional chaotic maps is more effective for secure communication in human-centered IoT to present a provably secure short signature technique.

以人为中心的物联网环境下基于分数混沌图的短签名方案

介绍

物联网 (IoT) 由各种智能设备组成，用于通过在线服务共享感测数据。将直接联系人们以检查他们的健康参数，并通过智能设备集中收集报告。要求是在发送方和接收方之间交换数据期间保护消息，以应对人为恶意攻击。文献中讨论了各种基于签名的方案以提供安全通信。然而，智能设备需要通过确保关键的安全强度来完成轻量级任务。基于签名的方法的一个重要问题是它会在大量签名和验证过程中产生更多的计算开销。

目标

在这项研究中，我们引入了一种高效的短签名方案（SSS），它使用分数混沌映射（FCM）在基于物联网的智能设备中进行安全通信，其安全性与基于 FCM 假设的随机预言密切相关。

方法

在这项研究中，我们使用 FCM 设计了新的短签名方案。所提出的方案由四个子算法组成，如下所示：设置、密钥生成、签名和验证。我们使用了基于 FCM 的不太严格的操作来执行签名和验证程序，类似于人工在有效文件上签名，然后根据见证人对其进行验证。

结果

提议的 SSS 提供了比目前建立的签名方案更好的安全保证。SSS 相对于 DSA 方案的主要优势在于，在验证阶段和签名阶段它需要更少的计算；它保留了保护程度。所提出的 SSS 占用更少的带宽用于存储、通信和计算资源；特别适用于无线设备和智能卡。

结论

我们得出的结论是，分数混沌地图的使用对于以人为中心的物联网中的安全通信更有效，以提供可证明安全的短签名技术。
