The security model using the method of code noising is considered. It is assumed that the information blocks of length $k$ contain a fixed message $m$ of length $l\leq k$ on a fixed position $q$, $1\leq q\leq k-l+1$, and an observer gets noisy codewords of length $n$ through a binary symmetric channel with error probability $({1-\Delta})/2$, $0\Delta\leq1$. The aim of the observer is to find the unknown message $m$, when position $q$ is unknown, and the length $l$ is known. We propose a method for finding $m$ and obtain an estimate for a sufficient number of observed codewords needed to recover the message $m$ in this way.
Keywords: code noising, repeated data transmission.
