We consider a secure lossless source coding problem with a rate-limited helper. In particular, Alice observes an independent and identically distributed (i.i.d.) source <formula formulatype="inline"> <tex Notation="TeX">$X^{n}$</tex></formula> and wishes to transmit this source losslessly to Bob over a rate-limited link of capacity not exceeding <formula formulatype="inline"><tex Notation="TeX">$R_{x}$</tex> </formula>. A helper, say Helen, observes an i.i.d. correlated source <formula… CONTINUE READING
