A right scrambler 'mixes' columns of the public key. It makes system more resistant to structural attacks at the little extra cost of a few additional columns.

In this paper, we present a new PKC based on the idea of a right scrambler | a special non-singular matrix by which the public key is multiplied to the right. A.

We prove that any variant of the GPT cryptosystem which uses a right column scrambler over the extension field as advocated by the works of Gabidulin et al.
The attack is based on the fact that one of parameters, the column scrambler, is defined over the base field. In this paper, we focus on using GPT public key.
