In this article, we construct two new cryptosystems which use two different mod values. Our main purpose is  to  create fast and secure schemes by using two different mod values. We do encryption according to mod $N$ and decryption according to mod $N_{1}$ where $N$ is a multiple of $N_{1}$. We examine homomorphic properties and security of these encryption schemes. At the final part, we implement the schemes and measure their time complexities.
