| 總結: | Post quantum algorithms are being developed to be an answer to cryptography in the event where powerful quantum computers that can break current public key cryptosystems become a reality. NTRU is one of the post quantum cryptographic algorithms developed that is thought to be resistant to quantum attacks. NTRU is a lattice-based cryptosystem based on the hardness of solving the Shortest Vector Problem. The primary purpose of this project is to study NTRU, and to implement a lattice attack on the cryptosystem to demonstrate how using unsafe parameters could lead to a compromise of the algorithm. A lattice attack on smaller parameters was implemented to retrieve the private key from the public key and ciphertext. The results of the implementation were further used to: 1) examine the significance of parameter 𝑞 on successful lattice attack, and 2) compare the speed between NTRU and RSA. |
