Item A Blockchain-Based Audit Trail Mechanism: Design and Implementation: Design and implementation(2021-11-26) Regueiro, Cristina; Seco, Iñaki; Gutiérrez-Agüero, Iván; Urquizu, Borja; Mansell, Jason; Tecnalia Research & Innovation; CIBERSEC&DLTAudit logs are a critical component in today’s enterprise business systems as they provide several benefits such as records transparency and integrity and security of sensitive information by creating a layer of evidential support. However, current implementations are vulnerable to attacks on data integrity or availability. This paper presents a Blockchain-based audit trail mechanism that leverages the security features of Blockchain to enable secure and reliable audit trails and to address the aforementioned vulnerabilities. The architecture design and specific implementation are described in detail, resulting in a real prototype of a reliable, secure, and user-friendly audit trail mechanism.Item Mechanisms and Dynamics of Mineral Dissolution: A New Kinetic Monte Carlo Model: A New Kinetic Monte Carlo Model(2019-10-01) Martin, Pablo; Manzano, Hegoi; Dolado, Jorge S.; Tecnalia Research & InnovationMineral dissolution is a fundamental process in geochemistry and materials science. It is controlled by the complex interplay of atomic level mechanisms like adatoms and terraces removal, pit opening, and spontaneous vacancy creation that can be gradually activated at different energies.
