32 Blockchain and agricultural supply chains traceability: research trends and future challenges
قابلیت ردیابی زنجیره تامین کشاورزی و بلاکچین : ​​روند تحقیق و چالش های آینده-2019
Blockchain is today one of the most interesting and debated research topics. Blockchain technology was implemented for the first time in the financial sector a few years ago. However, it is currently used in many other areas, such as: healthcare, smart cities, smart contracts, energy markets, government sector. The success of this technology mainly lies in the following properties: reliability, transparency, immutability. In this study, we collect and analyze the main contributions in the literature about the application of blockchain in the agricultural sector, focusing on food traceability issues. Considering the quick growth of this technology and the high number of published documents in recent months, there is a need to catalog the different methodologies, proposed by the various scholars. Our aim is to detect the current research trends and possible future challenges. In the agricultural context, the need for an adequate traceability system is motivated by several bad habits and problems, such as the wide use of pesticides and fertilizers in fruits and vegetables, which are extremely harmful for human health. Moreover, in the last few years, the consumers’ attention about the quality of agricultural products has considerably increased. The present study shows that the blockchain technology is still in its early stage. Although there are several proposals in the literature, still a limited number of applications have been put into use in the real context. From the point of view of scientific research, only some countries are investing in this technology: China and United States are among the most active, but Italy is also very involved in this phenomenon. Overall, the blockchain technology appears very promising, but still many efforts are needed to reach the maturation stage.

33 An elliptic curve cryptography based mutual authentication scheme for smart grid communications using biometric approach
رمزنگاری منحنی بیضوی مبتنی بر طرح احراز هویت متقابل برای ارتباطات شبکه هوشمند با استفاده از روش بیومتریک-2019
Smart grid (SG) provides a suitable adjustment in the amount of power generation by providing the ability to supervise consumer behavior. SG uses in the smart system to encourage cultural heritage because it is accountable for providing power without any interruption. SG is one of the vital components to authorize smart systems with a lot of smart features to attract visitors to come and visit heritage. In SG, environment security and privacy are the major concern for communications. An authentication protocol provides secure communication between users and service provider for security and privacy purpose. Several authentication protocols are available in the literature. However, they are enabled to known security attacks easily or they are not computationally efficient for SG communication. In the present paper, we design an ECC-based mutual authentication protocol for smart grid communication using biometric approach. The present framework satisfy various security features such as replay attack, user anonymity, man in the middle attack, key freshness, message authentication, session key agreement, impersonation attack, non-traceability and non-transferability. Further, the proposed protocol takes much less communication and computation costs compared with other existing protocols in SG environment. Therefore, our scheme is convenient for practical application in SG communication

34 A novel credential protocol for protecting personal attributes in blockchain
یک پروتکل معتبر جدید برای محافظت از ویژگی های شخصی در بلاکچین-2019
This paper proposes a novel user-centric and privacy-preserving credential scheme over the blockchain. The proposed protocol allows users to access services without revealing sensitive attributes. This new paradigm is based on an efficient short signature, which uses pairing and self-blindable credentials that are verifiable on the blockchain. Our scheme achieves the advanced features of anonymity, unlinkability, and untraceability of users. Moreover, confidentiality of users’ attributes and unforgeability of their credentials are met. We provide security proofs and a real-world use-case where the protocol can be ap- plied. To empirically assess the performance of our solution, the cryptographic components and communications between the various involved actors are implemented using GO and Java. In addition, an implementation for an online trading use case based on Hyperledger Fabric is provided. Finally, we prove the efficiency of our work by presenting some exper- imental results and exhibiting comparisons with known traditional credentials schemes.

35 An organization-friendly blockchain system
یک سیستم بلاکچین سازگار با سازمان-2019
Transaction privacy protection has always been the subject of interest in blockchain-based transaction system. The one-time public key method commonly used in current system does not perfectly achieve this function. Other technologies such as Mixcoin and zk-SNARKs also confront with some centralization and efficiency drawbacks. In this paper, we propose a new organization-level privacy protection mecha- nism for blockchain-based transaction system, which realizes the transformation of transactions between users to transactions between organizations, and further achieves a balance between privacy protection and security supervision. Specifically, we formalize the definition of this system architecture and give its generic construction and concrete implementation through the basic cryptography modules such as digi- tal signature, public key encryption, group signature, zero-knowledge proof and range proof of committed value. Analysis and experiment results show that our system satisfies three important properties of pro- tocol security, transaction privacy and identity traceability, which makes it suitable for various trading scenarios, especially for public-to-public transactions.

36 Modeling the blockchain enabled traceability in agriculture supply chain
مدل سازی بلاکچین قابلیت ردیابی در زنجیره تأمین کشاورزی را فراهم می کند-2019
Blockchain Technology (BT) has led to a disruption in the supply chain by removing the trust related issues. Studies are being conducted worldwide to leverage the benefits provided by BT in improving the performance of the supply chains. The literature reveals BT to offer various benefits leading to improvements in the sustainable performance of the agriculture supply chains (ASC). It is expected that BT will bring a paradigm shift in the way the transactions are carried in the ASC by reducing the high number of intermediaries, delayed payments and high transaction lead times. India, a developing economy, caters to the food security needs of an ever-growing population and faces many challenges affecting ASC sustainability. It is therefore essential to adopt BT in the ASC to leverage the various benefits. In this study, we identify and establish the relationships between the enablers of BT adoption in ASC. Thirteen enablers were identified from the literature and validated by the experts before applying a combined Interpretive Structural Modelling (ISM) and Decision-Making Trial and Evaluation Laboratory (DEMATEL) methodology to envision the complex causal relationships between the identified BT enablers. The findings from the study suggest that, among the identified enablers, traceability was the most significant reason for BT implementation in ASC followed by auditability, immutability, and provenance. The findings of the study will help the practitioners to design the strategies for BT implementation in agriculture, creating a real-time data-driven ASC. The results will also help the policymakers in developing policies for faster implementation of BT ensuring food safety and sustainable ASCs.

37 Boundary conditions for traceability in food supply chains using blockchain technology
شرایط مرزی برای ردیابی در زنجیره های تأمین مواد غذایی با استفاده از فناوری بلاکچین-2019
Traceability of ingredients in food supply chains has become paramount in a world in which markets become global, heterogeneous, and complex and in which consumers expect a high level of quality. The food supply chain consists of many organizations having different interests and are often reluctant to share traceability information with each other. Blockchain has been advocated for improving traceability by providing trust. Yet, practice proved to be more stubborn. The goal of this paper is to identify boundary conditions for sharing assurance information to improve traceability. Four cases in the food supply chain have been investigated using a template analysis of 16 interviews. Eighteen boundary conditions categorized in business, regulation, quality and traceability categories have been identified. Some boundary conditions were found in all supply chains, whereas others were found to be supply chain specific. Standardization of traceability processes and interfaces, having a joint platform and independent governance were found to be key boundary conditions before blockchain can be used. Our findings imply that supply chain systems have first to be modified and organizational measures need to be taken to fulfill the boundary conditions, before blockchain can be used successfully.

38 An intelligent blockchain-based system for safe vaccine supply and supervision
یک سیستم مبتنی بر بلاکچین برای تهیه و نظارت بر واکسن های ایمن-2019
Immunization is an indispensable mechanism for preventing infectious diseases in modern society, and vaccine safety is closely related to public health and national security. However, issues such as vaccine expiration and vaccine record fraud are still widespread in vaccine supply chains. Therefore, an effective management system for the supervision of vaccine supply chains is urgently required. As the next generation of core technology after the Internet, blockchain is designed to build trust mechanisms that can change current information management methods. Meanwhile, the development of machine learning technologies provides additional ways to analyze the data in information management systems. The main objective of this study is to develop a “vaccine blockchain” system based on blockchain and machine learning technologies. This vaccine blockchain system is designed to support vaccine traceability and smart contract functions, and can be used to address the problems of vaccine expiration and vaccine record fraud. Additionally, the use of machine learning models can provide valuable recommendations to immunization practitioners and recipients, allowing them to choose better immunization methods and vaccines.
