英文摘要：

Authenticated encryption scheme achieves both confidentiality and integrity, which brings a wide range of research and application scenarios. Its design involves block ciphers, hash functions, stream ciphers and other research. It covers all aspects of symmetric cryptography and has good theoretical study and practical value. The design and analysis methods of authenticated encryption are becoming maturer. In recent years, CAESAR competition set off a new round of research upsurge of authenticated encryption scheme. A large number of new design are springing up, providing some good study models to related fields. While there are still some unresolved issues and challenges for future research, worthy of further analysis and discussion. This paper discusses advances in authenticated encryption schemes, design patterns, related problems and challenges and future study trends and makes the corresponding overview and summary.
