摘　　要：为避免机房的数字化信息在传输过程中受到网络攻击,以Present分组密码算法为基础,提出一种安全传输方法。针对机房软硬件设备计算资源有限的前提条件,改进Present算法的框架结构与加密过程。在加解密过程中添加常数变换、密钥白化两步骤,设计基于对角线分区的P盒位置换策略,得到Present优化算法。将Present优化算法作为加解密手段,结合身份双向认证策略,完成数字化信息的安全传输。实验结果显示,所提方法的吞吐量较高,端-端平均时延较低,能量消耗与丢包量较少,且较好地抵御了多次恶意攻击,说明上述方法具有较强的攻击抵御能力,能够实现数字化信息完整、安全的传输。In order to avoid network attacks on the digital information in the computer room during transmission,a secure transmission method is proposed based on Present block cipher algorithm.Improve the framework structure and encryption process of the Present algorithm to address the premise of limited computing resources for software and hardware devices in the computer room.During the encryption and decryption process,two steps are added:constant transformation and key whitening.A P-box position exchange strategy based on diagonal partitioning is designed to obtain the Present optimization algorithm.Using the Present optimization algorithm as an encryption and decryption method,combined with a bidirectional identity authentication strategy,to achieve secure transmission of digital infor⁃mation.The experimental results show that the proposed method has higher throughput,lower end-to-end average la⁃tency,less energy consumption and packet loss,and better resistance to multiple malicious attacks,indicating that the method has strong attack resistance ability and can achieve complete and secure transmission of digital informa⁃tion.
