GPT cryptosystem for information network security

Abstract

We consider network communication with adversaries which can listen or tap some original packets, outgoing from the source to the sink. To provide information security we use a modified public key cryptosystem GPT (Gabidulin-Paramonov-Tretiyakov) based on rank codes. The main contribution of this paper is a novel approach to choosing main parameters. It allows to enhance network security. © 2013 Infonomics Society.
