A Smart Contract Architecture to Enhance the Industrial Symbiosis Process Between the Pulp and Paper Companies - A Case Study

BLOCKCHAIN AND APPLICATIONS

Abstract
Pulp and Paper Companies collaborate to monitor and monetize waste and create value from their by-products. This process of Industrial Symbiosis requires the creation and maintenance of trusted and transparent relationships between all entities participating in these networks, which is a constant challenge. In this context, a blockchain-based system can help in establishing and maintaining these networks, serving as a ground truth between companies operating at a national or a global scale. This paper proposes a scalable and modular blockchain architecture design using smart contracts to enhance the industrial symbiosis process of the Pulp, Paper, and Cardboard Production Sector companies in Portugal. This design comprehends all entities participating in the network. The implementation of this design assumes the use of a permissioned ledger built using Hyperledger Fabric to provide the required trust and transparency between all entities. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Secure Remote Storage of Logs with Search Capabilities

Journal of Cybersecurity and Privacy

Abstract
Along with the use of cloud-based services, infrastructure, and storage, the use of application logs in business critical applications is a standard practice. Application logs must be stored in an accessible manner in order to be used whenever needed. The debugging of these applications is a common situation where such access is required. Frequently, part of the information contained in logs records is sensitive. In this paper, we evaluate the possibility of storing critical logs in a remote storage while maintaining its confidentiality and server-side search capabilities. To the best of our knowledge, the designed search algorithm is the first to support full Boolean searches combined with field searching and nested queries. We demonstrate its feasibility and timely operation with a prototype implementation that never requires access, by the storage provider, to plain text information. Our solution was able to perform search and decryption operations at a rate of, approximately, 0.05 ms per line. A comparison with the related work allows us to demonstrate its feasibility and conclude that our solution is also the fastest one in indexing operations, the most frequent operations performed.

Controlled and Secure Sharing of Classified Threat Intelligence between Multiple Entities

Abstract
The Malware Information Sharing Platform (MISP) enables the sharing of cyberthreat information within a community, company or organisation. However, this platform presents limitations if its information is deemed as classified or shared only for a given period of time. This implies that this information should to be handled only in encrypted form. One solution is to use MISP with searchable encryption techniques to impose greater control over the sharing of information. In this paper, we propose a controlled information sharing functionality that features a synchronisation procedure that enables classified data exchange between MISP instances, based on policies and ensuring the required confidentiality and integrity of the shared data. Sequence charts are presented validating the configuration, the data synchronisation, and the data searching between multiple entities.

On the feasibility of blockchain for online surveys with reputation and informed consent support

Authors
de Sousa, HR; Pinto, A;

Publication
Advances in Intelligent Systems and Computing

Abstract
Economical benefits obtained by large Internet corporations from gathering and processing user information at a global scale led the European Union to legislate on behalf of individual rights and the privacy of personal information. Data collectors, in particular, must now obtain proof of the user’s consent for every single operation comprising their data. Considering the conflicting interests of all involved parties, we propose that consent should be stored in a blockchain. By being a distributed, immutable and verifiable ledger, the blockchain presents itself as an almost tailor-made solution to harmonize conflicting interests while enabling the regulators’ supervision. © Springer Nature Switzerland AG 2019.

On the use of the blockchain technology in electronic voting systems

Authors
Alves, J; Pinto, A;

Publication
Advances in Intelligent Systems and Computing

Abstract
The benefits of blockchain go beyond its applicability in finance. Electronic Voting Systems (EVS) are considered as a way to achieve a more effective act of voting. EVS are expected to be verifiable and tamper resistant. The blockchain partially fulfills this requirements of EVS by being an immutable, verifiable and distributed record of transactions. The adoption of EVS has been hampered mainly by cultural and political issues rather than technological ones. The authors believe that blockchain is the technology that, due to the overall attention it has been receiving, is capable of fostering the adoption of EVS. In the current work we compare blockchain-based EVS, identifying their strengths and shortcomings. © Springer Nature Switzerland AG 2019.
