Abstract

A new family of so called reducible rank codes, which are a generalization of rank product codes [8], is introduced. A McEliece type [1] public key cryptosystem based on these codes and on the idea of a column scrambler is proposed. The column scrambler ‘mixes’ columns of a generator matrix of a code. It makes the system more resistant to structural attacks such as Gibson’s attacks [5, 6]. Possible attacks are studied. The possibility of using the system for combined error protection is investigated. The system is found to be secure against known attacks for public keys of about 10 kbits
