| Abstract: | It is an inevitable trend to provide authentication encryption modes of operation, which satisfy all kinds of requirements, and have good performance such as high-efficiency, high security, low-cost and simple structure. Authenticated encryption modes based on block ciphers provide both privacy and authenticity of users’ information. As they have many good properties： high-speed, easy standardization, high-efficiency in hardware and software implementation, they have been widely used in the field of information security. In this paper, we give a survey on authenticated encryption modes based on block ciphers, and discuss further research trend in the future. |
