Abstract

With the progress in data exchange by the electronic system, the need for information security has become a necessity. Due to the growth of multimedia application, security becomes an important issue of communication and storage of different files. To make its reality, cryptographic algorithms are widely used as essential tools. Cryptographic algorithms provide security services such as confidentiality, authentication, data integrity and secrecy by encryption. Different cryptographic algorithms are commonly used for information security in many research areas. Although there are two encryption techniques, asymmetric and symmetric, the simpler symmetric encryption technique is employed for testing file security system. In this study, the performance evaluation of the most common two symmetric encryption algorithms such as TEA and Blowfish algorithm is focused on the execution time intervals. Simulation has been conducted with many types of file encryption like .pdf, .txt, .doc, .docx, .xlsx, .pptx, .ppt, .xls, .jpg, .png and most common video file formats by using Java Programming Language.
