Abstract
Exchange of data over the internet is increasing day by day. Security is the main issue in communication over a network. Protection must be given against intruders. Hence Cryptography plays a vital role in providing security. There are two basic types of cryptography: Symmetric Key and Asymmetric Key. Symmetric Key uses same or single key for encryption and decryption whereas Asymmetric Key uses separate keys for encryption and decryption. The most commonly used are the Symmetric Key algorithms. The strength of these algorithms is based on the difficulty to break the original messages. In this paper, a new Symmetric Key algorithm called as KED (Key Encryption Decryption) using modulo69 is proposed. Here not only alphabets and numbers are used, but special characters have also been included. Two keys are used in which one is a natural number which is relatively prime to 69 and finding the inverse modulo69 of it and the other key is a random number generated by the proposed key generation method. The proposed algorithm is used for Encryption and Decryption.
