Cubic multivariate cryptosystems based on big field constructions and their vulnerability to a min-rank attack
In this work we analyze the security of cubic cryptographic constructions with respect to rank weakness. We detail how to extend the big field idea from quadratic to cubic, and show that the same rank defect occurs. We ...Universidad Nacional de Colombia Sede Medellín Facultad de Ciencias Escuela de Matemáticas. 2019
