The Gabidulin-Paramonov-Trejtakov (GPT) public-key cryptosystems, based on Gabidulin codes, seem to have some advantages over McEliece's public-key cryptosystems using Goppa codes. In this paper we define the optimal distortion parameter for the GPT cryptosystem to be the distortion parameter that maximizes the workload of the best (structural or decoding) attack. The work factors achieved by the...
This paper presents computed and measured (in a reduced-scale model) distributions of electric field strength E and current density J at ground level under practical HVDC transmission lines in corona. The iterative method of Ref. 1 is used to solve the corona equations for E and J in the case of unipolar lines. Since under bipolar lines, only two unipolar regions (negative and positive) exist at the...
