论文摘要
ITRU密码系统是公共密钥密码系统，也是NTRU密码系统的已知变体之一。 ITRU密码系统不是在截短的多项式环中工作，而是基于整数。作者声称，与经典的NTRU相比，ITRU具有更好的功能，例如具有简单的参数选择算法，可逆性和成功的消息解密和更好的安全性。在本文中，我们提出了针对ITRU密码系统的攻击技术，它主要基于对密文字母的简单频率分析。
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.
