All Today's reality Sensitive information is progressively utilized in correspondence over the web. Accordingly Security of information is the greatest worry of web clients. Best arrangement is utilization of some cryptography algorithm which scrambles information in a few code (cipher) and moves it over the web and again decoded (decrypt) to original information. The area of cryptography manages the strategy for passing on data safely. The objective is to permit the planned beneficiaries of a message to get the message appropriately while intrude on overhang droppers from understanding the message. Cryptography incorporates a bunch of strategies for scrambling or camouflaging information so it is accessible just to somebody who can reestablish the information to its unique structure. In current PC frameworks, cryptography gives a solid, prudent reason for keeping information arranged and for checking information outrage. While our customary cryptography strategies, such for AES (encryption) and RSA (marking), function admirably on frameworks which have sensible handling power and memory capacities, these don't scale well into a world with inserted frameworks and sensor organizations. Hence, lightweight cryptography strategies are proposed to beat a significant number of the issues of regular cryptography. This work decides to add to the overall assemblage of information in the space of traditional cryptography by fostering another cross breed method of encryption of plaintext. The cryptosystem plays out its encryption by scrambling the plaintext utilizing Vigenere Cipher and further utilizing the ciphertext to encode the plaintext again utilizing Polybius Cipher.
