The Application of Improved DES Algorithm in Moblie Monitoring

Abstract:

In cryptography, the DES algorithm is known to be advantageous by utilizing the mechanisms of grouping and symmetric private key. The algorithm is critical in the field of encryption. It is adaptive to various applications for encryption in many different systems, especially in the embedded system of Internet of Things (IOT) and the Next-generation Convergence Networks. In this paper, an improved scheme is presented in order to overcome the easily attacked shortcomings. This method is to improve the complexity of encryption key in the process and thus to enhance the ability in resisting attacks, so that we use two keys to crosswise encrypt and the safety of the algorithm is further strengthened. In this paper, the improved algorithm is applied in smartphone-based monitoring of broadcasting transmission systems, so as to realize the transmission of data encryption functions.
