%0 Journal Article %T Notes on two methods for direct construction of probabilistic LFSR sequences of third order %A L houssain El Fadil %A Danilo Gligoroski %J Mathematics %D 2009 %I arXiv %X In \cite{Tm}, the authors give two public key encryptions based on third order linear sequences modulo $n^2$, where $n=pq$ is an RSA integer. In their scheme (3), there are two mistakes in the decryption procedure %U http://arxiv.org/abs/0907.2606v2
