Biography

I received my M.Sc. degree in Communications Engineering in 2022 from the Technical University of Munich. Since October 2022, I have been a doctoral researcher under the supervision of Professor Antonia Wachter-Zeh.

My research interests include code-based cryptography and coding theory.

NTRUEncrypt and NTRUSign

Keywords:
lattice-based cryptography

Description

NTRU is a well-known lattice-based cryptosystem that can be described using polynomial rings. The public-key encryption scheme NTRUEncrypt has the advantage of having short keys with fast encryption/decryption algorithms and is considered a viable candidate for post-quantum cryptography. There is also a signature scheme called NTRUSign, though its security is less trusted compared to NTRUEncrypt.

The task of the student is to understand and summarise how the two schemes work, the attacks against them in the literature and the countermeasures proposed to resist these attacks.
