Treffer: CRYPTANALYSIS OF ITRU.

ITRU cryptosystem is a public key cryptosystem and one of the known variants of NTRU cryptosystem. Instead of working in a truncated polynomial ring, ITRU cryptosystem is based on the ring of integers. The authors claimed that ITRU has better features comparing to the classical NTRU, such as having a simple parameter selection algorithm, invertibility, and successful message decryption, and better security. In this paper, we present an attack technique against the ITRU cryptosystem, and it is mainly based on a simple frequency analysis on the letters of ciphertexts. [ABSTRACT FROM AUTHOR]

Kriptosustav ITRU je kriptosustav s javnim ključem i jedna od poznatih inačica kriptosustava NTRU. Umjesto na prstenu krnjih polinoma, ITRU kriptosistem zasnovan je na prstenu cijelih brojeva. Njegovi autori su tvrdili da ITRU ima bolje značajke u odnosu na klasični NTRU, poput jednostavnog algoritma za odabir parametara, invertibilnosti, uspješnog dešifriranja poruka i bolje sigurnosti. U ovom članku predstavljamo tehniku napada na ITRU kriptosustav, koja se uglavnom temelji na jednostavnoj frekvencijskoj analizi slova šifrata. [ABSTRACT FROM AUTHOR]
