The separation of manufacturing and design processes in the integrated circuit industry to tackle the ever increasing circuit complexity and time to market issues has brought with it some major security challenges. Chief among them is IP piracy by untrusted parties. Hardware obfuscation which locks the functionality and modifies the structure of an IP core to protect it from malicious modifications or piracy has been proposed as a solution. In this paper, we develop an efficient hardware obfuscation method, called Mystic (Mystifying IP Cores), to protect IP cores from reverse engineering, IP over- production, and IP piracy. The key idea behind Mystic is to add additional state transitions to the original/functional FSM (Finite State Machine) that are taken only when incorrect keys are applied to the circuit. Using the proposed Mystic obfuscation approach, the underlying functionality of the IP core is locked and normal FSM transitions are only available to authorized chip users. The synthesis results of ITC99 circuit benchmarks for ASIC 45nm technology reveal that the Mystic protection method imposes on average 5.14% area overhead, 5.21% delay overhead, and 8.06% power consumption overheads while it exponentially lowers the probability that an unauthorized user will gain access to or derive the chip functionality.

                            A Blockchain Platform for Protecting Intellectual Property: Implications for Additive Manufacturing
                        
                    
    
            Prior studies have already predicted that enforcement of IP on the additive manufacturing industry will not be successful due to the widespread use of file-sharing technologies, similar to the entertainment and music industry. This paper discusses the capabilities of Blockchain technology for protecting IP in the design and manufacturing area. A conceptual framework for a digital platform is defined in this paper and further, a survey study of engineering design and manufacturing students has been conducted to identify the main motivation behind developing these platforms and the types of features that should be included in Blockchain-based IP platforms for asset protection, particularly for product design. In addition, respondents provided their opinions about the type of industry that might be affected more by the threat of counterfeiting products and the role of Blockchain-based IP systems on the growth and development of innovation.

            null (Ed.)Computerized systems and software, which allow optimizing and planning the processes of production, storage, transportation, sale, and distribution of goods, have emerged in the industry. Scheduling systems, in particular, are designed to control and optimize the manufacturing process. This tool can have a significant effect on the productivity of the industry because it reduces the time and cost through well-defined optimization algorithms. Recently, the applicability of blockchain technology has been demonstrated in scheduling systems to add decentralization, traceability, auditability, and verifiability of the immutable information that this technology provides. This is a novel contribution that provides scheduling systems with an additional layer of security. With the latest version of Hyperledger Fabric, the appropriate levels of permission and policies for access to information can be established with significant levels of privacy and security, which prevent malicious actors from trying to cheat or abuse the system. Different alternatives exist to manage all processes associated with the operation of a blockchain network, and among them, providers of blockchain as a service have emerged. Chainstack stands out for its simplicity and scalability features to deploy and operate a blockchain network. Our goal in this work is to create a solution for secure storage of and access to task-scheduling scheme on the consortium blockchain and inter-planetary file system as a proof of concept to demonstrate its potential and usability.more » « less

            The potential of blockchain technology is immense and is currently regarded as a new technological trend with a rapid growth rate. Blockchain platforms like Bitcoin are public, open, and permission-less. They are also decentralized, immutable, and append-only ledger; those ledgers can store any type of data and are shared among all the participants of the network. These platforms provide a high degree of anonymity for their users' identity and full transparency of the activities recorded on the ledger while simultaneously ensuring data security and tamper-resistance. All nodes on the network collectively work to validate the same set of data and to achieve group consensus. Blockchain platforms like Ethereum have the ability to develop smart contracts and embed business logic. This allows the use of blockchain beyond cryptocurrency as a business management solution. Besides the issues of scalability and the expensive nature of most blockchain systems, many attributes of traditional public blockchain are not desirable in a business or enterprise context such as anonymity, full transparency, and permissionless. Permissioned blockchain platforms like Hyperledger Fabric are designed and built with enterprise and business in mind, retaining the desirable qualities of blockchain for enterprise while replacing the qualities of blockchain that are undesirable for the enterprise. In this paper, we present a comprehensive review on the Hyperledger enterprise blockchain technologies.more » « less

            With live video streaming becoming accessible in various applications on all client platforms, it is imperative to create a seamless and efficient distribution system that is flexible enough to choose from multiple Internet architectures best suited for video streaming (live, on-demand, AR). In this paper, we highlight the benefits of such a hybrid system for live video streaming as well as present a detailed analysis with the goal to provide a high quality of experience (QoE) for the viewer. For our hybrid architecture, video streaming is supported simultaneously over TCP/IP and Named Data Networking (NDN)-based architecture via operating system and networking virtualization techniques to design a flexible system that utilizes the benefits of these varying internet architectures. Also, to relieve users from the burden of installing a new protocol stack (in the case of NDN) on their devices, we developed a lightweight solution in the form of a container that includes the network stack as well as the streaming application. At the client, the required Internet architecture (TCP/IP versus NDN) can be selected in a transparent and adaptive manner. Based on a prototype we have designed and implemented maintaining efficient use of network resources, we demonstrate that in the case of live streaming, NDN achieves better QoE per client than IP and can also utilize higher than allocated bandwidth through in-network caching. Even without caching, our hybrid setup achieves better average bitrate over live video streaming services than its IP-only alternative. Furthermore, we present detailed analysis on ways adaptive video streaming with NDN can be further improved with respect to QoE.more » « less

            The objective of this study is to provide an overview of Blockchain technology and Industry 4.0 for advancing supply chains towards sustainability. First, extracted from the existing literature, we evaluate the capabilities of Industry 4.0 for sustainability under three main topics of (1) Internet of things (IoT)-enabled energy management in smart factories; (2) smart logistics and transportation; and (3) smart business models. We expand beyond Industry 4.0 with unfolding the capabilities that Blockchain offers for increasing sustainability, under four main areas: (1) design of incentive mechanisms and tokenization to promote consumer green behavior; (2) enhance visibility across the entire product lifecycle; (3) increase systems efficiency while decreasing development and operational costs; and (4) foster sustainability monitoring and reporting performance across supply chain networks. Furthermore, Blockchain technology capabilities for contributing to social and environmental sustainability, research gaps, adversary effects of Blockchain, and future research directions are discussed.more » « less
