Abstract :
The aim of this paper is to construct wiretap channel codes based on the the notion of a hash property for an ensemble of functions (sparse matrices). The theorem implies that codes using sparse matrices can achieve the optimal rate. Furthermore, the fixed-rate universal coding theorem for a wiretap channel is also presented.
