Comparative Study of Popular Cryptographic Techniques

In computer network, information has been broadly exchanging over the communication system but the security over the communication system is not very sufficient and the data can be breached by interceptors. To provide security over the communication system, cryptography technique is used. In this process, the primary information is changed over into jumbled data with the help of key. DNA cryptography is preferred to be highly secure technique than other cryptographic techniques due to its vast parallelism and a enormous amount of data can be inherit in any data molecule. This technique is more popular than other cryptography as this technique does not involve exchange of key. In this paper, various cryptographic techniques have been implement on different strings and the results are analyzed.
