Desarrollo e implementación del sistema de autenticación con tecnología de firma digital sobre aws para la Facultad Tecnológica de la Universidad Distrital Francisco José de calda

Abstract

This project focused on the implementation of a centralized digital signature system at the Francisco José de Caldas District University. To achieve this, AWS signature technology was used to securely authenticate documents and ensure the integrity of academic information. This initiative addressed the need to modernize administrative and academic processes, increasing trust and efficiency in digital document management. During the development of the application, a module based on the X.509 standard was implemented. This standard defines the formats of digital certificates, enabling document signing and verification. This implementation was essential to guarantee user data security and optimize administrative and academic processes, reducing the risk of document manipulation or loss. According to validation carried out with the administrative staff of the Francisco José de Caldas District University, it was identified that there is currently no tool to support this essential task in various academic areas. For this reason, this application was implemented, and tests were conducted using university documents in different formats, such as PDF, Word, JPG, and PNG. In each case, a hash of the document was generated, which was encrypted with the signer's private key to produce the digital signature. The results obtained demonstrated consistent response times and optimal performance in most cases, validating the effectiveness of the system in digital document management. To integrate the web system, API Gateway was configured and used, providing secure HTTP connections and invoking various Lambdas for the creation, assignment, signing, and validation of files corresponding to each user and document owner. Additionally, secure storage in S3 was implemented, linked to AWS Lambda, which helped protect user data and optimize administrative processes. The development of this digital signature system on AWS infrastructure not only guarantees the security and authenticity of academic documents but also provides the university with a scalable and reliable platform. The system was developed using Angular, a framework that facilitates the rapid creation of user interface views, characterized by its simple and efficient template syntax. The use of these services enables agile and efficient development, facilitating adaptation to the evolving academic environment and strengthening the digital ecosystem of the Francisco José de Caldas District University.
