  • A Systematic Analysis
    of Security in Blockchain

    28th Febrero 2023

    Our colleague Manuel Ángel Serrano together with María Isabel Ortega, Julio Moreno and Eduardo Fernández-Medina have presented the research article "A systematic Analysis of Securiyt" in the Journal of Information Science and Engineering, Vol. 39 No. 1, pp. 197-222.

    In this article we can see how due to the multiple recent attacks against blockchain systems, the need to strengthen their security is highlighted. The high economic impact of cryptocurrencies and the sensitive information proposed to be handled by their networks (e.g., implementation of notaries, electronic voting, ...) make security an essential aspect. The objective of this work is to determine the main security issues that have been identified in blockchain by following a well-known methodology called "Systematic Mapping Studies". This work aims to address the main security problems in blockchain technologies and analyze their solutions. Finally, a proposal is made to define a model for improving blockchain security. The purpose of this model is to enable a better understanding of the security and the typical structure of this type of environment.
