摘要

在物联网(IoT)的背景下,整体数据安全问题是复杂的,因为数据必须在三个关键点上得到保护,即1。2.生成点(物联网传感器);3.存储点;使用点(物联网执行器)。第2点可以通过区块链充分解决,区块链通过在分布式设置中安全透明地存储数据,从而提供卓越的不变性,使其在存储时具有防篡改性。然而,仅凭区块链无法根除物联网网络中的所有数据安全障碍,因为第1点和第3点仍然需要解决。在本文中,我们提出了一种新的安全元素和基于区块链的策略,称为SEBS,可以同时有效地保护所有3个点,从而实现真正意义上的轻,整体,高效的物联网数据安全。此外,我们详细介绍了SEBS在通用物联网网络场景中的实施,并展示了它如何将关键安全操作的性能提高多达31倍。接下来,我们提出了一种新的基于SEOVA或SE的离线验证算法来验证通过中介接收的数据是否真的属于区块链,从而解决了一个小众问题。

SEBS: A Secure Element and Blockchain Stratagem for Securing IoT
In the context of the Internet of Things (IoT), the issue of holistic data security is complex as data has to be secured at 3 critical points i.e., 1. Point of generation (IoT sensors), 2. Point of storage, 3. Point of usage (IoT actuators). Point 2 can be adequately addressed by Blockchain that offers remarkable immutability by storing data securely and transparently in a distributed setting, making it tamper-proof while in storage. However, blockchain alone cannot root out all the data security impediments in an IoT network as Points 1 and 3 still needs to be resolved. In this paper, we propose a novel Secure Element and Blockchain based stratagem called SEBS to effectively secure all 3 Points at once, thereby realizing light, holistic, efficient IoT data security in true sense. Further, we elaborate on SEBS implementation in a generic IoT network scenario and show how it improves the performance of critical security operations by as much as 31 times. Next, we address a niche problem by proposing a novel SEOVA or SE based offline verification algorithm to verify if the data received through intermediary really belongs to the blockchain.
