"Computational Cryptography: Investigation of NP-hard problems related to number-theoretic cryptography and symmetric ciphers"
1)BA/MA with Honours in Mathematics (University of Cambridge)
2)Master of Advanced Studies in Mathematics (Number Theory Group, University of Cambridge)
3)Master of Research in Security Science (Department of Security and Crime and Department of CS,UCL)
I'M ORIGINALLY FROM...
WHY I APPLIED TO THE SECURITY SCIENCE DTC
The multi-dimensionality of the real problems that we have to face in nowadays makes the multi-disciplinary research very crucial. In order to be able to contribute successfully to the security field you need to be able to understand solutions arising from many different other disciplines. The general idea behind the DTC is the promotion of this multi-disciplinary way of thinking and co-operation.
cryptanalysis of hash functions, cryptanalysis of cryptosystems, algebraic attacks, finite field algebra, computational complexity (especially multiplicative), optimization of arbitrary algebraic computations over general settings, optimization of cipher's representations for cryptanalysis use, computational and algebraic number theory
WHAT I DO WHEN I'M NOT STUDYING
MY CAREER ASPIRATIONS
Contribute scientifically to the area of security
WHAT KIND OF PARTNER ORGANISATION I'D LIKE TO WORK WITH AND WHAT I'D LIKE FROM THEM
IT consulting companies and laboratories which promote research on mathematics applied to computer science or on general security problems.
