Research on Data Trusted Encryption and Transport Technology for Intelligent Network Interaction Terminal

通过分析智能网荷互动特征,基于对称混合128比特位密钥AES-DES算法,研究互动终端数据可信加密传输技术,建立数据可信加密传输模型。首先使用混沌,修改S-box在AES中进行增强,使用混沌序列使得密钥空间无限大,并且使用密钥对静态S盒进行动态化;为了增加系统复杂性,AES集成在循环结构中,评估重点是加密-解密时间、吞吐速度和雪崩效应。仿真结果表明,传统AES算法和增强型AES算法性能评估几乎相同,但增强型具有更好的混沌性,可有效处理智能网荷互动过程中数据的复杂性问题并提高抗攻击能力。

Through analyzing the characteristic of intelligent network charge interaction,based on the symmetric hybrid key AES-128 bits and DES algorithm,this paper studies the interactive terminal credible data encryption transmission technology,a data encryption transmission trust model was set up.Specific for using chaos first,and then modify the S-box,enhanced in AES,using chaotic sequence makes key space infinite,and using the key to dynamic static S box.In order to increase the system complexity,AES is integrated in the loop structure,and the evaluation focuses on the encryption and decryption time,throughput rate and avalanche effect.The simulation results show that the traditional AES algorithm and the enhanced AES algorithm are almost the same in the performance evaluation,but the enhanced has better chaos,can enhance the system’s complexity and ability against the attack.
