XVII Reunión Españoña Sobre Criptología y Seguridad de la Información (RECSI 2022)
Del 19 al 21 de octubre de 2022, Santander, España.
In recent times, lattice-based cryptographic schemes have been presented as the most promising encryption schemes against quantum computation attacks. Currently, the National Institute of Standards and Technology (NIST) is in the process of setting new post-quantum standards in two categories: key encapsulation mechanisms and digital signatures. During the different phases of the standardization process the proposals presented have been deeply studied in several ways. Their performance has been, after the security of the algorithms, an important feature to be taken into account during the evaluation process. Each submission to the NIST call includes a performance analysis and the NIST reported about the comparison among the candidates. In this communication, we focus our work on how the different lattice-based algorithms perform their implementations. Moreover, we compare each algorithm to the others by running some tests in the same device, to obtain a result as fair as possible.
