A Novel Approach for Enhancement of Blowfish Algorithm by using DES, DCT Methods for Providing, Strong Encryption and Decryption Capabilities

Data safety has evolved into a critical requirement and duty in modern life. Most of our systems are designed such way that it can get hacked, putting private information at danger. As result, for numerous motives, we utilize various approaches to save as much possible on this data, regardless its varied formats, words, photographs, videos, so on. The data storage capacity mobile devices is restricted owing insufficient processing. In order develop safe MCC environment, security concerns must be studied analysed. This study compares the most widely used symmetric key encryption algorithms, including DES (Data Encryption Standard), Blowfish, TDES (Triple PRESENT, KLEIN. assessment algorithms based attacks, size, block with best outcomes their field.
