DOUBLE LAYER CRYPTOGRAPHY USING MULTIPLICATIVE CIPHER AND CHEMICAL PERIODIC TABLE

According to the present communication system one of the main concerns is secured transformation of data. In this paper we be inclined to propose a two-level encryption in this paper in the first level encryption we use the multiplicative ciphers and Cesar cipher in this level the plain text letters, we shall multiply the key numbers in this level and the second layer encryption we use periodic table exploitation the properties if the quality table, and thus use it for encrypting and decrypting in the same manners. For the information of network security in the second level encryption we will differently types of periodic table properties like atomic no, mass no, IUPAC name, chemical formula, and their properties.
