摘　　要：相比其他种类的医疗信息,医院网络信息的安全问题常常被忽视,为了及时发现外部恶意入侵医院的行为,实现对医院网络信息安全加密,设计一种医院网络信息双混沌系统安全加密方法。通过结合多策略非阻塞页面爬取技术与Heritrix框架设计医院网络信息采集策略,采集医院网络信息。设计由信息预处理单元、初始化单元、信息重组单元等构成的数据动态压缩算法,对采集数据压缩处理。基于分数阶Fourier变换与双混沌系统设计数据安全加密算法,实现信息的加密处理。测试结果表明,该方法的密匙敏感性很高,加密后信息的信息熵值接近于8,抗统计攻击性良好。Compared with other kinds of medical information,the security of hospital network information is often ignored.In order to detect the malicious invasion of the hospital in time and realize the security encryption of hospital network information,a security encryption method of hospital network information double chaos system is designed.The hospital network information collection strategy is designed by combining multi-strategy non-blocking page crawling technology and the Hertrix framework to collect hospital network information.The data dynamic compression algorithm composed of information preprocessing unit,initialization unit,information reorganization unit,etc.is designed to compress the collected data.Data security encryption algorithm is designed based on fractional Fourier transform and double chaotic system to realize information encryption.The test results show that the key sensitivity of this method is very high,the information entropy value of the encrypted information is close to 8,and the statistical attack resistance is good.
