Rainbow signature system is making effective use of the advantage of
multivariate public key cryptosystem (MPKC) and overcoming its defect.
However, the inventors had made mistake in estimating the time complexity of the attacks and
consequently it was pointed out
that the parameter setting which they proposed in the original paper was not sufficiently secure.
Here we discuss the time complexity further and
propose to improve the structure of the public key to make it more compact. |
