英文摘要 The NTRU system, with its simple structure, fast decryption speed and natural multi-key processing, has attracted much attention in post-quantum cryptographic algorithms, so this paper reviewed the research related to the NTRU system. Firstly, it introduced the research and development of NTRU, system introduction, analyzed the reasons for decryption failure, and summarized the key technologies based on NTRU system. Secondly, it gave the analysis and comparison of five fully homomorphic encryption schemes based on NTRU system, and summarized several general optimization methods. Finally, it pointed out the key problems to be solved by NTRU-based encryption schemes, indicates the future research direction, and provides reference for those who study NTRU system.
英文关键词 NTRU system; homomorphic encryption; decryption failure
