Abstract

With the increase in usage of Internet of Things devices (IoT), IoT is used in different sectors such as manufacturing, electric vehicles, home automation and healthcare. The IoT devices collected large volumes of data on different parameters at regular intervals. Storing a massive amount volume of IoT data securely is a complicated task. Presently, the majority of IoT devices use cloud storage to store the data, however, cloud servers require large storage and high computation. Due to third party cloud service provider (CSP) interaction, the management of IoT data security fully depends on the CSP. To manage these problems, a decentralized blockchain based secure storage is proposed in this work. In the proposed scheme, instead of CSP storage location, the patient health information is stored in the blockchain technique and the blockchain miners verify the transactions with the help of Elliptic Curve Cryptography (ECC). The miner verification process dynamically avoids adversary access. Similarly, the certificateless access is used in the proposed system to avoid certificate based issues. The blocks in the blockchain is going to be stored patient details in a decentralized storage location to avoid unauthorized access and ensure the authenticity of data. The use of blockchain eliminates the need for third party public auditing process through immutable storage. This work illustrates secure communication and immutable data storage without the intervention of CSP. The communication overhead reduced by nearly 10 to 40% and authentication improved by 10 to 20% while confidentiality increased by 5% in comparison to existing techniques. Through this technique, data confidentiality, integrity and availability is ensured.

使用物联网和基于区块链的分散数据存储的医疗保健数据收集
随着物联网设备(IoT)使用的增加,物联网被用于制造业、电动汽车、家庭自动化和医疗保健等不同领域。物联网设备定期收集大量不同参数的数据。安全存储大量物联网数据是一项复杂的任务。目前,大多数物联网设备使用云存储来存储数据,但云服务器需要大容量存储和高计算能力。由于第三方云服务提供商(CSP)的交互,物联网数据的安全管理完全依赖于CSP。为了解决这些问题,本文提出了一种基于分散区块链的安全存储方法。在该方案中,患者健康信息存储在区块链技术中,而不是CSP存储位置,区块链矿工借助椭圆曲线加密(ECC)验证交易。矿工验证过程动态避免对手访问。类似地,在建议的系统中使用无证书访问来避免基于证书的问题。区块链中的区块将把患者的详细信息存储在一个分散的存储位置,以避免未经授权的访问,确保数据的真实性。区块链的使用通过不可变存储消除了对第三方公共审计过程的需求。这项工作说明了在没有CSP干预的情况下安全通信和不可变数据存储。与现有技术相比,通信开销减少了近10%到40%,身份验证提高了10%到20%,机密性提高了5%。通过该技术,保证了数据的保密性、完整性和可用性。
