Undergraduate Thesis in EECS in Cryptography in Greek

I am an undergraduate student in Electrical Engineering and Computer Technology Department in Patras, Greece and I am looking for a Greek PhD student to do my thesis in Cryptography. The topic is "Breaking the RSA Cryptosystem," that is trying to find p and q, where p, q large primes, p-q large, knowing n = p * q. The Thesis should consist of the research of the Bibliography and code in C handling huge numbers. I have already written some code in C, handing huge integer numbers, that is addition, substraction, multiplication and division, so I need someone to debug and finish that code.
