Term Project ITCS4301 Information Security, Fall 2022/2023

.Task Develop a network application for testing block ciphers in different modes of operation. Implemented in the project block ciphers should allow both encryption and decryption. Block ciphers and operation modes to choose are given in Tables 1 and 2 respectively. Communicating parties shall be represented as processes running on two separate computers connected via some channel.

Grading policy and requirements 4. Materials on term project should contain: - A report on the work done - Word document file of report; source codes and executables of developed applications; necessary examples of plaintexts and cipher-texts and so on; necessary for work special libraries if any. So, the submitted material should contain source code, all information concerning 2 description of your project, and it should be possible to launch from it your application, to enter necessary data, to view obtained results. 5. Report on term project should have: - cover page (department, course, title of term project, students name, instructors name, date); - Task definition; - Brief definition of an algorithm and mode of operation to be implemented; - Description of developed application and its source codes; - Description of tests conducted to verify correct work of your application, provide screenshots of working program, and comment them; - Experiments results and discussion; - Conclusion - references to used articles, textbooks, web-sites and so on, if any

Table 1. Rlock cinhers Table 2. Modes of block cipher operation Select any two algorithms from Table 1 and any mode of operation from Table 2. Selected algorithms are to be implemented and investigated for the selected mode of operation
