	abstract = {Secure Multi-party Computation (SMPC) is a family of protocols which allow some parties to compute a function on their private inputs, obtaining the output at the end and nothing more. In this work, we focus on a particular SMPC problem named Private Set Intersection (PSI). The challenge in PSI is how two or more parties can compute the intersection of their private input sets, while the elements that are not in the intersection remain private. This problem has attracted the attention of many researchers because of its wide variety of applications, contributing to the proliferation of many different approaches. Despite that, current PSI protocols still require heavy cryptographic assumptions that may be unrealistic in some scenarios. In this paper, we perform a Systematic Literature Review of PSI solutions, with the objective of analyzing the main scenarios where PSI has been studied and giving the reader a general taxonomy of the problem together with a general understanding of the most common tools used to solve it. We also analyze the performance using different metrics, trying to determine if PSI is mature enough to be used in realistic scenarios, identifying the pros and cons of each protocol and the remaining open problems.},

	abstract = {Este trabajo pretende analizar el paradigma de la Computaci{\'o}n Segura Multiparte y sus posibles aplicaciones en el campo de la criptograf{\'\i}a. Se plantea como modelo alternativo, mas escalable y seguro al uso de m{\'o}dulos hardware de seguridad para aplicaciones que requieran de Terceras Partes Confiables. Concretamente, se ha integrado un protocolo de criptograf{\'\i}a RSA multiparte con la librer{\'\i}a certbuilder, para la creaci{\'o}n de certificados X.509. De esta forma se asegura que la creaci{\'o}n de los certificados ra{\'\i}z de la Infraestructura de Clave Publica se realiza de forma que la generaci{\'o}n de claves y firma de este se ejecute {\'\i}ntegramente sobre el sistema multiparte, con un modelo de tres partes que trabaja con circuitos aritm{\'e}ticos, sin que ninguna de ellas, de forma aislada, tenga posibilidad de comprometer la clave privada correspondiente. Para comprobar la viabilidad del sistema se han realizado pruebas de generaci{\'o}n de certificados con diferentes longitudes de clave, siendo el proceso determinante la creaci{\'o}n de las claves. Los elevados tiempos hacen que una aplicaci{\'o}n como esta no sea asumible en otros escenarios, pero creemos que para el caso de la creaci{\'o}n de los certificados ra{\'\i}z de una infraestructura de clave p{\'u}blica las garant{\'\i}as avanzadas de seguridad compensan el tiempo extra.
