As part of my Mathematics degree I'm taking a Discrete Mathematics module which partially covers Public Key Cryptography but does not at all enter it in depth.
I'm currently working on a project that involves writing about the process, security and efficiency (in terms of calculation/processing speed) of a few PKC systems.
I understand the processes and how to discuss the security of these systems, but I'm struggling with what makes a PKC system "good" in terms of efficiency, at least comparatively. I'm only considering the following 3 systems:
- El Gamal, &
On a basic level I can compare key sizes and ciphertext expansion, but further than that I'm a bit lost; especially in terms of terminology when attempting further reading. Any direction or advice would be greatly appreciated.
