摘要
移动互联网方便了信息的采集与传输,但从一定程度上也增加了网络用户个人隐私被泄露的风险。针对移动互联网条件下,传统信息采集安全加密技术信息处理耗时长、安全性不足的弊端,提出一种基于时空混沌的信息采集加密技术研究。对信息的加密层次进行分析,并研究了时空混沌加密技术的序列生成过程及密度分布情况;给出了时空混沌加密技术条件下的信息采集加密流程,基于流密码机制设计了信息采集的系统加密模型,最后使用流密码和双密钥算法,完成明文与密文之间的自由无损转换,实现了移动互联网条件下信息的安全采集和传输。实验数据表明,时空混沌加密技术在4种不同文件加密解密过程的耗时较少,密文转换输出效果更好,在相同的加密时间内受到的网络攻击次数较少、安全性更高。
Mobile Internet facilitates the collection and transmission of information, but to a certain extent, it also increases the risk of network users’ personal privacy being leaked. Under the conditions of mobile Internet, the traditional information acquisition security encryption technology has long time consuming and lack of security. This paper presents a research on information acquisition and encryption based on spatiotemporal chaos. The encryption level of information is analyzed, and the sequence generation process and density distribution of spatio-temporal chaotic encryption technology are studied. The information collection and encryption process under the condition of spatiotemporal chaotic encryption is given. Based on the stream cipher mechanism, the system encryption model is designed. Finally, the stream cipher and double key algorithm are used. It completes the conversion between plaintext and ciphertext, and realizes the secure collection and transmission of information under the condition of mobile Internet. The experimental data show that the time and space chaos encryption technology is less time-consuming in 4 different files, and the effect of the cipher translation is better, and the number of attacks on the network is less and the security is higher in the same encryption time.
