The growing amount of data in university networks is creating big challenges for encryption methods. This is especially true for symmetric algorithms like AES (Advanced Encryption Standard) and DES (Data Encryption Standard).
Security Issues: DES uses a key that is only 56 bits long. This makes it weak against modern computers. Back in 1998, someone cracked a DES key in less than 24 hours! By 2023, computers have gotten so powerful that breaking DES is even easier.
Data Speed: DES can handle about 16 megabytes of data per second. This might be fine for smaller networks, but university networks often deal with much more data, usually around 1 gigabit per second or higher. So, DES can’t keep up.
Better Security: AES uses longer keys—128, 192, or 256 bits—which makes it much more secure than DES. As of 2023, no one has found a way to break AES, making it the best choice for encryption.
Faster Speeds: AES can process up to 12 gigabits per second on modern computers. This means it’s perfect for university networks, where a lot of important data like research papers and student records is shared frequently.
In short, AES can handle the increasing data in university networks much better because it is secure and fast. DES, on the other hand, is mostly outdated and not suitable for today's needs. Moving from DES to AES can greatly improve both the security and efficiency of how universities share data. As schools keep embracing digital tools, using AES should be a top priority to keep data safe.
