What can be done as a practical part in a thesis on cryptography?

Question

IT education

I study at a pedagogical university. In my last year I got interested in cryptography. I am writing a thesis on the topic "Application of cryptographic tools for the protection of modern information systems and networks." Advise what can be implemented in the practical part of the work. Thanks in advance for your advice.

Answer 1

for example, write an encoder for vpn or some kind of tls implementation for portals with a personal account

Answer 2

If you want a simple option - change the topic to "using cryptography to protect data in modern information systems" and write an analogue of TrueCrypt (encrypt some files on your disk). If you want difficulties, it is better to consult a teacher, there are millions of difficulties. The first thing that came to mind was to implement the transfer of encrypted data using an EDS (I encrypted it on my computer, on another computer I confirmed with the help of an EDS that you are the one who decrypted it).
You can also write something with steganography - the topic is interesting and extensive, but you will have to radically change the topic of the diploma)

Answer 3

develop a miniature version of the blockchain - for a diploma, I think, quite for myself. maybe later even where it will come in handy)
