Protocolos criptográficos de identificação baseados em reticulados

TL;DRAbstract

One of the main concerns of the field of Information Security is access control, which refers to the restriction of access to several kinds of resources, such as data, places, devices, services and others.Identification schemes are cryptographic algorithms that allow verifying with some level of certainty if an identity claim is legitimate.Therefore, such schemes make possible to provide access control and grant privileges only to authorized individuals whose identities have been previously verified.Lattice-based algorithms are particularly interesting as the cryptography community believes them to remain secure even to quantum computers attacks, as opposite to some cryptosystems used today based on Number Theory problems.For this reason, identification schemes based on lattices have received growing attention lately.In this work, we address the main recent developments of lattice-based identification schemes.After introducing the algorithms, we make a comparative analysis of the selec
