摘要：This paper introduces Encryption and Decryption in terms of Cryptography Techniques. Cryptography is "The science of protecting data" & Network Security "keeping information private and Secure from unauthorized Users".This paper gives the Fundamental Requirements for the Data Transmission, the security attacks like Interruption, Interception and Modification of the data Transmission. The Cryptographic Process explaining through a generalized function is discussed through which encryption and decryption is done by the algorithm to encipher and decipher the data for a word/line[11].The computational time of the algorithm hava a major impact on the determining the efficiency of the algorithm.In this paper,a symmetric key algorithm is proposed for larger amount of data.
