The Department of Mathematics, in cooperation with the Continuing Education Unit at the College of Science, held a lecture entitled “Encryption Systems and Their Applications” presented by Assist. Prof. Dr. Ali Habeeb Kishmar, Dr. Saad Muhammad Ali and Dr. Alaa Hussein Lafta, in the presence of a number of students, researchers and those concerned with this topic.
The lecture aimed to introduce cryptography, which is the science that uses mathematics to encode data so that no one can read it without a decryption key, as well as the use of encryption for a variety of purposes, such as maintaining the confidentiality of sensitive data, ensuring privacy, preventing message fraud, and storing and transferring data in a way that protects them from hacking or theft. The lecturer then reviewed two types of encryption, indicating that it is symmetric encryption used for both encrypting and decrypting messages, sharing the same goal by making sure that the person who owns only the right key can read what has been written.
