摘要

区块链技术改变了传统医疗系统集中管理的形式,构建分布式、安全的医疗数据共享机制,实现数据价值最大化。然而,量子算法的先进性能给目前基于经典数学难题的区块链密码算法带来了严重的威胁。针对基于区块链的医疗物联网(BIoMT)系统,提出了首个基于身份的量子安全指定验证者签名(ID-DVS)方案。该方案基于短整数解(SIS)问题的点阵假设,被认为可以抵抗量子攻击。当这些数据在不同的医疗机构之间共享时,身份机制有助于建立交易可追溯机制。指定验证者机制还可以防止未经授权的用户访问数据,从而提高医疗数据共享过程的安全性。其次,在随机oracle模型中证明了该ID-DVS方案能够实现匿名性和不可伪造性的安全特性。它还可以捕捉后量子安全。在此基础上,对密钥大小和时间消耗进行了性能分析,结果表明该ID-DVS方案比其他类似方案效率更高。因此,本工作支持安全的医疗数据共享,保护用户和医疗数据的隐私。

Quantum-safe identity-based designated verifier signature for BIoMT
Blockchain technology changes the centralized management form in traditional healthcare systems and constructs the distributed and secure medical data-sharing mechanism to achieve data value maximization. However, the advanced capabilities of quantum algorithms bring a serious threat to current blockchain cryptographic algorithms which are based on classical mathematical difficulties. This paper proposes the first quantum-safe identity-based designated verifier signature (ID-DVS) scheme for blockchain-based Internet of medical things (BIoMT) systems. This scheme is constructed based on the lattice assumption of the short integer solution (SIS) problem, which is believed to resist the quantum attack. The identity mechanism helps to establish a transaction traceability mechanism when this data is shared among different medical institutions. The designated verifier mechanism also prevents unauthorized users from accessing data to improve the security of medical data-sharing processes. Next, this ID-DVS scheme is proved in random oracle model, which can achieve the security properties of anonymity and unforgeability. It also can capture the post-quantum security. Then, the performance analysis of the key size and time consumption are presented, and the results show that this ID-DVS is more efficient than other similar schemes. Therefore, this work supports secure medical data-sharing and protects the privacy of users and medical data.

期刊介绍: The Journal of Systems Architecture: Embedded Software Design (JSA) is a journal covering all design and architectural aspects related to embedded systems and software. It ranges from the microarchitecture level via the system software level up to the application-specific architecture level. Aspects such as real-time systems, operating systems, FPGA programming, programming languages, communications (limited to analysis and the software stack), mobile systems, parallel and distributed architectures as well as additional subjects in the computer and system architecture area will fall within the scope of this journal. Technology will not be a main focus, but its use and relevance to particular designs will be. Case studies are welcome but must contribute more than just a design for a particular piece of software. Design automation of such systems including methodologies, techniques and tools for their design as well as novel designs of software components fall within the scope of this journal. Novel applications that use embedded systems are also central in this journal. While hardware is not a part of this journal hardware/software co-design methods that consider interplay between software and hardware components with and emphasis on software are also relevant here.
