Implementação do Algoritmo Criptográfico Ascon em Aplicações Móveis com React Native e TypeScript

Abstract

This work presents the implementation of the lightweight cryptography algorithm Ascon in a mobile environment using TypeScript and React Native. The focus is to demonstrate the practical applicability of Ascon in security scenarios, including authenticated encryption and hash computation for strings and files. The ascon-js library was used to enable these operations, while auxiliary libraries facilitated file selection and reading. Performance tests were conducted on three devices with different hardware capabilities, evaluating the execution times of encryption and hashing operations. The results showed that Ascon is efficient on resource-constrained devices, highlighting its potential as a viable solution for lightweight cryptography in mobile environments. Despite the advantages of React Native, limitations were identified in terms of performance compared to native code and direct hardware access. This work concludes that while native development may be more suitable for applications requiring fine-tuned optimizations, Ascon proves to be a promising alternative for security in mobile devices.
