摘要
为了有效地解决网络建设管理中的安全问题,需要进行网站管理地址泄露下网页信息快速加密。但是采用当前方法对网页信息进行加密时,无法获取网页信息密钥各态历经的安全容量,存在网页信息加密效率低的问题。现提出一种基于相位响应独立性的网站管理地址泄露下网页信息快速加密方法。上述方法先融合于反向导频估计原理得到合法用户的网页信息状态,给出网站管理地址泄露下的信道输入与输出关系,引入中间变量将网站管理地址泄露下的信道转化为不同的级联,利用小波理论形成明文信息小波序列,并对网页明文信息小波变换序列进行加密操作,引入归一化相似度衡量密文序列和明文序列间的相似程度,将粒子群思想理论和混沌理论相融合构建网页信息快速加密目标函数,通过对目标函数最小化促使网页信息的加密效果最优化。仿真证明,所提方法加密精度高,可以为网站的建设与管理提供有力的依据。
A fast eneryption method of webpage information under leakage of website management address is pro- posed based on independent of phase respond. Firstly, the webpage information status of legal user integrated with es- timation principle of inversion pilot frequency is obtained, and the relationship between import and export of channel under leakage of website management address is provided. Then the intermediate variable is introduced to transform the channel into different cascades. Moreover, the wavelet theory is used to generate wavelet sequence of plaintext, and the encryption operation for the wavelet conversion sequence carried out. The degree of similarity with normaliza- tion is introduced to measure similarity between cryptograph sequence and plaintext sequence, and the target function of fast encryption of webpage information is built integrating particle swarm theory with chaos theory. Finally, the en- cryption effect is prompted to be optimal through minimizing target function. Simulation shows that the method has high encryption precision. It can provide power gist for construction and management of website.
