摘　　要：随着万物互联的程度不断加深,计算机计算能力的不断发展和进步,人们对数据的安全性的要求也在不断地提高,尽管AES算法具有接口简单、实现方便和安全性高等特点,然而,传统的AES算法已不能满足当下发展环境下的安全需求,急需探究如何在保证加密算法的安全性以及所占用的计算资源基本保持不变的前提下,使得加密算法的实现过程更加简洁高效。基于此,文章提出了一种改进的AES算法,实验表明,该算法具有很好的加密性能。As all things connected degree deepening, continuous development and progress of computer computing ability, people demand for the security of the data is in constant increase, despite the AES algorithm has a simple interface, easy to implement and the safety is high, however, traditional AES algorithm cannot satisfy the security requirements of the development environment, It is urgent to explore how to make the implementation process of encryption algorithm more concise and efficient on the premise of guaranteeing the security of encryption algorithm and the computing resources occupied basically unchanged. Based on this, an improved AES algorithm is proposed in this paper. Experiments show that the algorithm has good encryption performance.
