Comparison of Dynamic DES with Existing Symmetric Key Algorithms

The concept of security is fundamental to networking. The basic objective of security is to defend against various types of assaults on these networks that hold sensitive data. By altering criteria such as key size, altering the number of iterations and ultimately using confusion box as the S-box, the security of cryptographic algorithms can be increased. Data exists in different forms such as text, images, audio and video. In DES, S-boxes are used to increase the security of the data. All of these 8 S-boxes have 64 elements. Unique numbers in the 0-15 range can be found in each row. These S- boxes are generated dynamically by our suggested system depending on the key and no storage of these elements are required. The comparison of Dynamic DES with other symmetric algorithms like DES, AES and Blowfish yields better results for Dynamic DES in terms of Balance, Bit difference, Time and Memory needed for Execution.
