ABSTRACT:

In this paper, a modified method of QC-LDPC McEliece cryptosystem is presented. Authors of [3] suggested that the recovery of Q is possible by an adversary using power trace method. To overcome with this problem, we present a modification in the existing scheme so that QC-LDPC McEliece cryptosystem by using a random linear non-singular matrix. And also we have tried to hide the structure of the generator matrix. The modified scheme has the ability to detect all the errors and correct nearly up to 30% of the errors that occurs. Thus, it has better error correcting capacity than the existing schemes.
