Since a smart dust Internet of Things (IoT) system includes a very large number of devices sometimes deployed in hard-access areas, it is very difficult to prevent security attacks and to alleviate bottleneck phenomena. In this paper, we propose a lightweight blockchain scheme that helps device authentication and data security in a secure smart dust IoT environment. To achieve our goals, (1) we propose the structure of the lightweight blockchain and the algorithm of processing the blockchain. In addition, (2) we reorganize the linear block structure of the conventional blockchain into the binary tree structure in such a way that the proposed blockchain is more efficient in a secure smart dust IoT environment. Experiments show that the proposed binary tree-structured lightweight blockchain scheme can greatly reduce the time required for smart dust device authentication, even taking into account the tree transformation overhead. Compared with the conventional linear-structured blockchain scheme, the proposed binary tree-structured lightweight blockchain scheme achieves performance improvement by up to 40% (10% in average) with respect to the authentication time.

Binary Tree Structure

Searchable symmetric encryption that supports dynamic multikeyword ranked search (SSE-DMKRS) has been intensively studied during recent years. Such a scheme allows data users to dynamically update documents and retrieve the most wanted documents efficiently. Previous schemes suffer from high computational costs since the time and space complexities of these schemes are linear with the size of the dictionary generated from the dataset. In this paper, by utilizing a shallow neural network model called “Word2vec” together with a balanced binary tree structure, we propose a highly efficient SSE-DMKRS scheme. The “Word2vec” tool can effectively convert the documents and queries into a group of vectors whose dimensions are much smaller than the size of the dictionary. As a result, we can significantly reduce the related space and time cost. Moreover, with the use of the tree-based index, our scheme can achieve a sublinear search time and support dynamic operations like insertion and deletion. Both theoretical and experimental analyses demonstrate that the efficiency of our scheme surpasses any other schemes of the same kind, so that it has a wide application prospect in the real world.

Based on software Pro/ENGINEER and Visual C++ 2005，sub-module of parametric design of assembly with wide universality was done by using Pro/TOOLKIT, and the design procedure was introduced in details. Assembly relation of sub-components is transformed into binary tree structure to store and search parts, and the assembly relation is displayed by CTreeCtrl control. The corresponding parts can be quickly found in the binary tree. Engineering drawing was automatically generated and displayed by ProductView after loading a part, and in this way dimensions of different parts can be modified according to engineering drawing in asynchronous mode. The sub-module can meet the needs of parametric design of parts in the integrated simulation system.

Security Enhancements

Current research in Internet of Things (IoT) is focused on the security enhancements to every communicated message in the network. Keeping this thought in mind, researcher in this work emphasizes on a security oriented cryptographic solution. Commonly used security cryptographic solutions are heavy in nature considering their key size, operations, and mechanism they follow to secure a message. This work first determines the benefit of applying lightweight security cryptographic solutions in IoT. The existing lightweight counterparts are still vulnerable to attacks and also consume calculative more power. Therefore, this research work proposes a new hybrid lightweight logical security framework for offering security in IoT (LLSFIoT). The operations, key size, and mechanism used in the proposed framework make its lightweight. The proposed framework is divided into three phases: registration, authentication, and light data security (LDS). LDS offers security by using unique keys at each round bearing small size. Key generation mechanism used is comparatively fast making the compromise of keys as a difficult task. These steps followed in the proposed algorithm design make it lightweight and a better solution for IoT-based networks as compared to the existing solutions that are relatively heavy weight in nature.

Binary Tree Structure

In this paper we propose novel, binary-tree, asynchronous, nonlinear filters suitable for signal processing realized at the transistor level. Two versions of the filter have been proposed, namely the dilatation (Max) and the erosion (Min) one. In the proposed circuits an input signal (current) is sampled in a delay line, controlled by a multiphase clock. In the subsequent stage particular samples are converted to 1-bit digital signals with delays proportional to the values of these samples. In the last step the delays are compared in digital binary-tree structure in order to find either the Min or the Max value, depending on which filter is used. Both circuits have been simulated in the TSMC CMOS 0.18?m technology. To make the results reliable we applied the corner analysis procedure. The circuits were tested for temperatures ranging from -40 to 120?C, for different transistor models and supply voltages. The circuits offer a precision of about 99% at a typical detection time of 20 ns (for the Max filter) and 100 ns for the Min filter (the worst case scenario). The energy consumed per one input during a single calculation cycle equals 0.32 and 1.57 pJ, for the Max and Min filters, respectively.
